Earthwise GS70015 15-Amp Garden Corded Electric Chipper, Collection Bin

I was weary of purchasing this because of the bad reviews but I saw a cheaper version of this had quite good reviews so I figured this could be a price point expectation? I've only spent 1 day with it, but chipped for about 4 hours straight and my initial impression is that this thing is pretty capable. I jammed it up so that I needed to actually unscrew the unit 3 times -- once within the first 5 minutes because I didn't know what I was doing, once because I was trying to be way too greedy with the branch I was putting through, and once unexpectedly. In all cases, I probably could have cleared the jam by using some channel locks or pliars and just pulling the branch out from the top feed / hopper and this is preferable as a first step if only because it takes like 40 turns to unscrew the bolt that allows you to access the blades. To me, three jams, 2 of them definitely my fault, over 4 hours is totally acceptable. Also to be clear, I mostly chipped dryer softwood, but did do a fair amount of hardwood and fresher, greener, wetter stuff. But here lies a few tips. 1. Use safety protection!! Full eye protection is a must. Branches will whip side to side unexpectedly. Use ear protection! It's loud and you only have one set of ears. Even gloves are recommended because sometimes when the branch whips and it's big enough it can hit you pretty hard. 2. Do not be afraid to use some violence! Many "jams" were avoided by just smashing the branch through the hopper using the provided hopper tool. Also whatever you can fit through the feeder will chip! I was worried in the beginning about not feeding anything too big, but it's really about how well you can guide it through the feeder, not so much the size of the branch (at least with softer woods). And this guiding process is a bit of an art (see more below) 3. Use a 12AWG/20A extension cord. Otherwise the voltage drop when this thing pulls full amps chewing through a big stick will result in big power loss! At least I assume that's the case and is the recommendation in the manual! 4. Hardwood is definitely.. harder. So use some restraint in combo with my violence recommendation depending on the wood. Violence on soft wood works pretty well. Violence with hardwood will likely jam the machine. Thus -- 5. Have patience and do some prep. The biggest problem is with wood that has sharp bends or big knots that you can't turn through the hopper feeding guide. If you or whoever you are working with prep the pieces for success, you will definitely have more fun feeding the beast. 6. RTFM! "Read the ___ manual". It has advice on alternating easier feeding wood between harder feeds ones to help keep the chipper clear and recommends wet wood in between dry pieces. I personally didn't have any trouble with the limited wet / fresh wood but I chipped 95% older, dryer, soft wood (which it absolutely massacres). 7. You will definitely improve with time! The amount of violence I used definitely decreased over the day as I learned how to find the best rotation technique to get the branches to feed more smoothly into the chipper. My only "critique" is that it does chip into fairly small mulch (which is called out in the item description). This is totally fine and expected but I am kind of curious what the larger mulcher is like as I think I would probably prefer that end product, but not sure. I had pretty low expectation but it met them, definitely. And by the end of day 1 with the thing, I feel it has already paid itself off for the price. In the beginning of the day I thought okay maybe this is about a 4 star, but once *I* learned how to use the thing more properly, I feel it is probably a 5 star product. I mean for the price this thing is a beast!! I'm sure there are use cases where this thing just doesn't keep up but for me, this thing cleans up! Too bad it will soon cost 2.5x as much with tariffs as it's made in China. Thank you to our wise King for lowering the prices of products for those of us that actually work for a living. I don't know about the cheaper chippers on Amazon but (electrical) safety wise this thing is also ETL listed and has overload protection. It claims it is "built to last". We will see! Recommended!

This machine does a wonderful job of chipping limbs within it's size range, and when leaves and debris make it down the hopper throat, it mulches them well. Unfortunately, getting limbs fed to the blades is relatively easy, but the hopper does not feed leaf material to the blades very well. To be safe, I assume, the throat of the hopper is shaped like a pair of binoculars and only a few inches across, and material that is small and flexible, such as leaves or pine needs or even twigs have to be driven down the hopper throat with the provided plastic ram. while it's effective, it can be unbearably slow. The engine is strong and not terribly noisy, which is nice for large jobs. The material is ejected from the bottom of the machine through slot that has a plastic grate-like bar that spans the exit slot. If the material is damp, green, or sappy, it tends to grab the grate, and before long, creates a jam. Clearing the jam is not a difficult process but it is tedious and time consuming. This machine is sturdy and powerful enough to its intended purpose. It's also quite safe to operate by design. It would be a great suburban yard maintenance/garden supplement tool. It does its job well, but it's not designed to handle big jobs. I wouldn't even consider mulching the leaves in fall for a large yard. I suspect if the loading port was enlarged enough to make quicker work of larger amounts, it wouldn't be as safe, but the design does limit its use.

Update October 2019: I've used this thing on and off (I never throw away trimmed branches - it's free mulch!), finally the blades got dull. It was very easy to unscrew them, lazily drag it back and forth on a coarse sharpening stone for about 5 min, put them back, and the chipper works as good as new. I didn't realize it at first, but blades are double sided, so I could have simply flipped them and used the other side ... But I wanted to see how long my sharpening job will last)). When the blades were dull, it started jamming a bit due to last thick but short chunks getting caught in the blade, but not too much (with the cross "thingy" gone - see below - jamming isn't an issue at all, really. And that collection bin is still the best. Happy chipping!.. January 2016 original review: I have used this thing for a day, and so far I am extatic. I hope it’s going to be reliable; just in case I purchased a 2-year warranty. Honestly, I don't know why other two brands of wood chippers out there sell so much better than this one. They look awkward and don’t have a receiver container. I was a bit apprehensive to get it for the lack of reviews, but there were 2 things going for it: very similar “chinese wonder” had excellent reviews on youtube and seemed so easy to "unjam" (one knob), and the container to collect the output (which works out beautifully and is a good size). This chipper seemed very "logical" to me, it has all that a chipper needs to have in my mind, larger acceptable diameter than other brands on Amazon, and it seems to be well-made. I guess, the time will tell how well. In a few hours that I used it, the pile in the picture diminished by 2/3, and it jammed on me ONCE (my fault, I put a wedge-shaped chunk of wood in it, that was thin, but wider than recommended diameter), took me less than 1 minute to get it out and keep going. You gotta love that! I didn’t put sticks over 1 1/2” into it (as many people report that electric chippers don’t really live up to the max diameter promise. (I don’t have much of thick ones anyway). The chipper didn’t do all that well with thin brush, it processed it, but the length of the sticks coming out was 2-3”. Nor a major defect in my eyes. It didn’t do well with a clump of weeds either. It milled it into pulp, but I had to open it and clear the chamber. I don’t consider it a true jam (the blade was still spinning), because at that point the receiving container was full and might have prevented the stuff from coming out, I didn’t have another clump to give it a second shot. Either way, I’m fine with it. My main goal was wood chipping, and wood chipping it does. Also, I must say that it is rather quit. I have sensitive ears, and always put on ear muffs when using my table saw. With this chipper I was perfectly fine without ear protection. It looks like perfect gadjet for a weekend warrior. It definitely will not see much of heavy use with me. Some sticks and twigs from our trees (this load is an exception, we got rid of a large bush that was overtaking our patio). If I don’t have enough, now and then I might collect some branches in the surrounding woods to make more bedding for my bird cage (I find that grass or wood chips blend in bird you-know-what better than paper or newspaper:). This way I know for sure that it’s clean wood and it’s safe for my birds to chew on if they want to. I also had an idea to try this wood mulch for growing mushrooms. It appears that all “regular” straw that you get at feed stores is hosed with either herbicides, or pesticids or the conbination of the two. Mushrooms have a tendency to accumulate all kinds of junk, so I’d rather have something ecologically clean to grow them on. I am not sure how well this will work out, but I’ll see in a few weeks… Happy chipping!

I bought this item to clear a bunch of fallen branches from a cluster of maple trees on my property. I assembled it and tested it immediately. It began to rain and wet the wood, so I stopped without a more thorough test. Here’s what I found – Pros: 1. The chipper was securely packed and was received undamaged. Light weight – about 35 lbs. 2. Comes with two wrenches needed for assembly. 3. Safety features are adequate. 4. Nice looking once assembled. 5. Easy to maneuver. 6. It chips DRY branches under 1½ inches thick – sometimes! 7. The chips are just the right size to use for mulch or compost. Cons: 1. The chipper was received three days later than promised. Unusual for Amazon. 2. The carton was received in the manufacturer’s box, not an Amazon over-carton. Contents could easily be seen by anyone with devious intentions. 3. During unpacking the chipper body spilled some wood dust and a few small wood slivers, indicating that it had been previously used (or perhaps tested at the factory). 4. Assembly by someone not mechanically inclined would be troublesome. The directions are sparse, confusing and incorrect when assembling the axel and wheels to the unit’s legs. The directions call for the legs to be secured to the body first, then the axel and its cover are supposed to be inserted into mounting holes in the legs. This is impossible, as the axel cover diameter is larger than the leg’s mounting holes. I had to remove one leg, insert one end of the axel, cover and washers in the secured leg, the other axel end in the loose leg, then reattach the loose leg to the body. Also, a 2-inch spacer is provided to separate the wheel of your choosing from one chipper’s leg. I found the spacer to be unnecessary. The wheels turn OK without a spacer. 5. Assembling the hopper ring to the hopper was impossible. The ring was just too large and misshapen to fit. No matter how hard I tried, I could not get the ring to snap into every hole provided in the hopper. I wound up breaking 3 of the ring’s tabs trying and had to secure the unseated ring with super glue. I don’t know why the ring isn’t integrally molded to the hopper to begin with. A very poor design and most annoying to assemble. 6. I was able to feed the machine a dozen known dry branches, each just under1½ inches thick and about 3-feet long. The chipper jammed twice (not good). The clearing process was relatively easy. Both jams, however, tripped a 15-amp GFI circuit breaker in the house (hmmm, not good at all). 7. As a safety measure, the manufacturer specifies using a 12 AWG extension cord, no longer than 25 feet in length. This tethers the chipper to the house, requiring distant wood to be gathered & hauled to the chipper (a bummer if one has a lot of distant wood to chip). 8. This chipper is marginally OK for very light work within 25 feet of the house. A small industrial grade gas-powered chipper is far better and mobile for heavier work at any distance. In summary, since I voided the warranty by breaking the hopper ring tabs, the unit cannot be returned. Sooo, I reckon I will have to keep it and deal with its sporadic operation or try to sell it to someone else.

Item assembled fast and easy. First use amounted to about a half full discharge bin which required a lot of branches to create. The branches were 1/4” to around 1.5” in diameter, a few with small leaves attached. This item worked on anything I could fit into it in the sense that a nice size mulch is created. The work did not get done without issues however. There is a learning curve. As the branches go over around 3/4”, they need to be very straight. Larger very curved or those with bends would not pass through the small input hole because larger branches are too rigid to be pulled or push assisted through, but rather get jammed because of the geometry involved. The other thing I had to learn was you must be careful with larger branches that will start okay through the input hole, but have joints along the branch from side branches that were removed. The irregular shaped joints might exceed the size of the input hole across ihe joint’s widest dimension. Then the branch would wedge in the hole and stop feeding. Sometimes when a curved or bent or large joint filled branch jams in the input hole, it will also jam inside the machine at the cutter blade. A branch jammed generally cannot be pulled out from the top. It is necessary to unscrew the lock nut that secures the top of the unit, pivot the top open, and then the jammed branch can be dislodged. Sometimes a jammed branch in the cutters will stall the motor and pop a circuit breaker. In my initial half bin of mulch I experienced 10 jams. Two jams I remedied by pulling the branch back out from the top. Eight times I needed to open the top to free the jammed branch. Two of the ten jams popped a circuit breaker. As I gained experience, the frequency of jams decreased. In summary, this item works well when it does not jam, but it is very easy to jam and then it is a bit of a pain to work with. You must be very careful of the shape, irregularities, and size of branches you feed into it or your work will slow way down dealing with jams. It is not meant for fast, easy, high volume work, but rather patient, slow cleanuo of waste branches that occasionally accumulate in your yard. The machine is not fast even when not jamming, branches feed in slowly by necessity. As I said, it does make nice size and shape mulch, but requires a lot of branches to get significant volume of mulch. I would give it 3.5 stars because for the price it is okay if you are patient and careful with realistic expectations, but I would not go 4 and certainly not 5 stars because it is too fussy and slow to work with.

I bought this unit back in 2021, and it officially gave up the ghost today (3/31/26). Honestly, I can’t complain—it survived years of steady use and a fair amount of abuse. Respect where it’s due. Performance-wise, it does its job well once you learn its personality. It absolutely prefers dry wood. Fresh, green branches, leaves, and especially vines? Those are its sworn enemies and will clog it up in no time. After some trial and error, here’s what I learned to keep things running smoothly: Strip off as many leaves as possible before feeding branches in. Feed branches thick-end first—this makes a noticeable difference. The hopper sounds helpful in theory, but in practice it just gets in the way. Removing it actually improves usability. Also, plan on opening and clearing jams every 30–40 branches—it’s part of the process. In short: it’s a bit high-maintenance and occasionally feels like it’s working against you… but if you respect its limits, it will absolutely get the job done. Would I buy it again? Probably—now that I know how to work with it instead of against it.

Pretty solid little unit, chips wood, branches, twigs very effectively. The biggest problem with it were leaves - leaves totally jammed up the exit port and I found myself taking it apart to clean it out every 20 minutes or so. It's not hard to do, but slowed down things. I've used tow behind gas chippers, and this isn't that. But it is good for a homeowner electric chipper. Does a good job, chips wood very effectively, but struggles a bit with leaves and requires frequent cleaning. Overall, I'm happy with the purchase. But don't get it if you're planning in chipping up a tree.

About 20 hours of use now over the last month. I did not know this kind of thing existed until recently. I wish I had bought something like this over a decade ago. There is a good review going over some use advice and I'll give some more. I chose this chipper over the competing chippers because the design seemed better although I frankly am not entirely clear what the operating mechanism is on some of the other competitors (most clearly are doing essentially the same thing). What seemed most different was the use of the integrated box to collect the mulched material. The other products did not have as good a way to collect the mulched material. After using it... I still think this was the better product although like other reviewers, I have not use a competing machine. Also some others reviewed had pictures of the mulched material which did not look chopped up like I wanted it and the picture on this one looked better processed. Although I really think this is a great machine.... it is not a magic machine and has to be fed properly to operate. The negative reviews seemed to just not want to understand that If you are doing leaves... that could be impossible with this device without clogging. The feed material can only have so much moisture laden leaves go through without them turning into a clog. Even heavily leafed branches can be a problem and the best solution is to alternate dead old branches with a leafier one as stated in the directions. The box for the mulch can be a problem in that it can back up and clog up the machine. You need to check the box frequently, initially pushing the mulch towards the back as the material enters the box at the front part. Don't try to get too much in the collection box or you will get the machine backed up. I have experienced what I will call clog up jams and a jam into the cutting blades. Both cleared easily enough once you unscrew the knob to open access to the cutting blade and the area which empties into the hopper. As noted so helpfully in another review.... you will quickly experience when clearing clogs that a sensor gets some junk in it which prevents the machine from operating... so take a look when you experience this problem and clear out the stuff that has gone into this small rectangular area.... unfortunately it is easy to get material in this area when clearing out a clog. With experience in operation you will learn to prepare feed material better to keep the device operating better without problems. So I would suspect any of these small chippers require quite a bit of care to operate successfully. What you gain is a huge reduction in volume and you are producing some nice mulch you can use.... Not big chips like purchased mulch or as produced by big chippers.... but material closer to wood shavings used for pet rodents. Safety... don't kid yourself.... what this is doing can cause injury. Although the design keeps your fingers from getting into the cutting parts effectively and keeps the cutting effectively shielded, you will want to wear gloves, ear protection and eye protection. Versus safety glasses... a full face shield might be nice. When stuff can fly about with things like this and wood cutting tools, I personally use a helmet type PAPR which provides excellent protection. There is much less material kicked into the air from this than from a chainsaw, jig saw or circular saw but some does pop out. Also in feeding branches in they can seriously jerk about at times which can sting a bit. Any chipper will do this I would think. The key to feeding is figuring about what can be fed and then learning to rotate the larger feed material about while pushing it in. With all the work clearing bushes, trimming trees over the years.... this would have been so great to have then ... but I am enjoying using it and highly recommend.

Funciona muy bien no he tenido problema, es ideal para ramas de 3 a 4 cm de grueso. Si las ramas son muy delgadas se puede atascar y las ranas muy gruesas no entran. Recomendable para un jardín con árboles medianos.

Works like a hot damn, I've already put a tonne if branches through it ( even an old shovel handle )it can clog up if you put too wet of branches through it ( fresh willow bungs it up a bit ) but, it's easy to clean out and inspect. I don't use the collection bin it came with, I mounted it onto my yard trailer. That small bin filled up too quickly is all ( the bin is now used to hold empty beer cans in my shop )

If you let the machine do the work without trying to jam pieces through it fast as I seen some people do on You Tube, it works just fine. If you put in branches with lots of green leaves, it has a tendency to plug up over time but it is easy to clear up. Demo video show lady putting leaves through the top but it is way too time consuming I consider it useless for shredding leaves. I am quite happy how it chipped the branches and twigs. It is far less noisy than gas operated chippers. Collection bin is a definite plus. As noted, the reason I did not give it five stars is it should not be advertised as leaf shredder (misleading) and it's tendency to plug up with branches with lots of green leaves.

En terminos generales funciona bien, lo único es que me imagine el proceso mas rápido y no encontré la opción de ordenar unas cuchillas adicionales.

I received several notifications that my shipment date was changed and then when I went to track it, it said that my package may be lost but it did come in later that day. The product works very well with branches but it is VERY difficult to put leaves through.
