Panana Portable Power Station 166Wh (45,000mAh), 180W Pure Sine Wave Lithium Battery Backup, Solar Generator with AC/DC/USB, Emergency Power Supply for Camping, Caravan, Home Blackout, Off-Grid

I'm using the smaller power station to power a USB light in my garage. It takes a literal age to recharge but once it IS charged it works fine. I've no way to test it properly,but it seems to last a good long while, about twice as long as the 20,000nah power bank I was using previously so that's about right, I think It's well made and feels like it'll last. Nice item at a nice price Edit. I've since discovered that it's charge rate is 30W, which explains the long charge time. All is still good , it's working well. Still great value

Battery can't hold its power. Moment you turn it on without anything plugged into it it looses 1% per minute, contacted the seller who told me it needs to be used and recharged a few times due to product being sat unused in the starage. Used it for two weeks and it got slightly better but still barely was able to charge a phone to 100%. Few days ago realised that both of the us ports don't even work!! Seller unhelpful won't replace or refund money, stay away!!!

Surprisingly lightweight and fantastic sturdy quality. It already had 40% battery charged and took no time to get to 108% once plugged into the mains. Tried catching my phone and the performance was good so it is very versatile and look forward to try on days out.

On the whole this has turned out a good item. There are a couple of cons with it but I would say more pros as follows: Pros - battery life - this is good as long as you use it for low power items. It it's certainly shows the likelihood of it having 45 amp hour as it states. If charging anything large that works off AC such as a Chromebook like I have the best thing is to use Qualcomm (and is still reasonably fast charge for it) and not the mains plug socket. I bought it for a mains powered Roland go keys digital piano which outputs 11.4 Watts and hardly uses any power from the power station - as little as 2% an hour so I'm very happy for this particularly use whilst travelling. Additionally I have used the Qualcomm and it's very good and the standard USB ports could be useful too i guess. I can also see it at some point the DC output using a barrel connector could be quite useful in my van too. Size and weight: very sleek build and also quite light at 2 kilograms especially if you stand it on its end it takes very little space up. It's also unquestionably rugged by design and build - I'm sure it will take some rotten Tumble. Cons - Charging- yes as other people have stated it is very slow charging and if you are charging it right off from almost 0 to 100% it would take a good five hours plus I'd say. Also in terms of what comes with the device you can only charge it up by the mains or I guess as I do in my vehicle via a small inverter plugged into the cigar light while driving - so if you're a way on a trip and you want to charge high powered items it's going to be more limited because you'd have to have a mains supply to recharge it unless you buy the solar panel of course which is quite big for such a small item and pretty pointless really?. so again if you're travelling you can use an inverter with your vehicle cigar DC output. Of course as its fairly small you could likely easier negotiate a public mains charge up in a cafe or library say than a larger power station or leisure battery certainly Inherent flaws - Its AC plug socket is slightly off kilter as other people have stated so means when you plug your plug in it's a few millimetres off alignment and at least should aim to stand device up tall and let gravity secure your AC plug in more. This may put some people off, however if you're just using it for a low-powered items like I am it's worth taking the chance but it may obviously point out why you wouldn't want to spend much more than £60 as I did for it. I think the price is generally pretty spot on for what it offers especially if they fix the AC plug alignment issue. In summary I believe this is worth buying and I'm still giving it four stars and has been knocked down from five for the plug socket alignment more than anything and everything else are things you can accept even the charging speed.

Took this on an overnight camping fishing trip with my son! This powerbank managed to charge my phone 5 times and my son's Nintendo Switch 4 times and still had charge left! It takes a while to charge the powerbank from empty but overall it's worth it.

This is a fantastic bit of kit. It has allowed me to light up a dark end of my hallway, especially this time of year.

DO NOT BUY. Product arrived on time, the only 1 star I will give for this product. First time useing it, there was a very loud squeal and my plug in device that i was useing it for became very hot. I switched it off. My device now does not work. Husband opened my device up to see what had gone wrong and test it and found that this portable battery had fried something on the motherbord. Tested the battery again on another device and the same thing happened. Apparently this is non refundable. This is a fire hazard. DO NOT BUY. (We were very careful to buy somthing that had suitable power for our area)

I use this to run my motor controlled telescope. A full charge runs it for several hours with no issues. Recently had a power cut and discovered a great use to keep my wifi router going, which is only possible because with fibre broadband you still need an electrically operated router! Life saver!
