1500W Pure Sine Wave Inverter 12V to 110V with Built-in 5V/2.1A USB Port,Hardwire Terminal, LCD Display,12V DC to 120V AC Converter for Home, RV, Truck (1500W)

UPDATED Review: For more than a year, I've used this ALFFAA 1500w (110v only) Pure Sine Wave inverter, with my [Insignia] 3.5cu Chest Freezer. Everything runs perfectly, with NO inverter fan noise. However; ALFFAA failed [at first] to start a [new Simzlife] 3.0cu freezer. I tried another inverter, the BELTTT, set at 120v. BELTTT ran the Simzlife freezer fine for a while, causing me to believe freezer needed 115v minimum (as user manual recommended twice). A few days later, the new Simzlife freezer started having problems with BELTTT too. Simzlife's manual clearly warns and states (on two different pages) that it requires 115v. Yet it failed to run consistently, even with 120v. Out of curiosity I purchased the "RCO410 3in1 Hard Start Capacitor" kit, to see if it would help. It did! Now the Simzlife runs consistently with BOTH inverters; ALFFAA and BELTTT. (ALFFAA is more quiet.) In summary; it was my new Simzlife freezer that was defective. This ALFFAA inverter CAN run both freezers simultaneously, and it definitely deserves 5 stars! --------------- Old Review: For more than a year, I've used this 1500w (110v only!) Pure Sine Wave inverter, with my 3.5cu Chest Freezer. Everything runs perfectly, with NO fan noise. (Some inverters run fan continuously, even during low energy usage.) However; this inverter failed to start/run a DIFFERENT 3.0cu freezer. This other freezer runs fine when used with another inverter, that produces 120v. Therefore my warning is this; be aware this ALFFAA inverter puts out 110v maximum! If you have any appliance that requires 115v or 120v, this ALFFAA might not work. I still give this inverter 5 stars.

Why did you pick this product vs others?: Awesome inverter, actually a quality inverter from a larger battery manufacture (Chins)! I ran this through the paces and it passed with flying colors in my review video (YT Chanel TackleThat if you want to see the whole video). Overall well built, good quality. THE ONE issue was there is a decimal place in the AMP output. Just ignore that.. it would read 5.5amp, but really that's around 55amps. Noise level: Very low noise level and I had to run it a long time for the fan to kick on. It has an oversized case which allows the heat to dissipate faster than the smaller units. Less fan speed needed. Build quality: Nice hi quality inviter with USB and digital gauges. Remember to IGNORE the "." in the Amp readout! Power: Great power, up to 1800w! I ran over 1500w with no issues! Value for money: Good value, good warranty, highly recommend!

Working great

works magic im able to run an air compressor from my truck battery safe mode does not heat up hot as other brand power consumption is great compatibility with all vehicles helps preserve battery life and not let it drains out completely.

It only worked for @ 60 days . Cheap product

works as it should but the fans kick on every 2 or 3 minutes and are loud. ridiculously loud. compared to a 1000 watt power simple inverter that runs the same refrigerator off the same battery bank. the fans on the power simple (which you cant find anymore unfortunately) kick in every so often and they are relatively quiet. this unit is only good for using in a shed or something since it's so loud. i don't recommend this inverter.

Test/Review Summary: From the time, I placed the order and received the item, was about 3-4 days. The item is packaged very well with nice thick box and thick foam protective material. In the box, I only received the inverter and a sheet of product information. You need to purchase your own cable/wire to connect from 12V battery terminals to the inverter terminals. Undersize cable will cause the inverter to not work properly (auto shutdown) and or fire hazard. This inverter is rated for 1,500W (110V about 12.6 Amp), meaning for the 12V battery system, the battery will need to supply minimum of 116 Amp continuous to the inverter. My recommendation is to get 2AWG or 1/0 cable and keep the distance short, such as max of 2 ft for positive and 2ft for negative. This is DC system, different from AC system. When you hook up directly to the inverter terminals from the battery, you will see spark. This can be dangerous. You need to use a pre-charge resistor to slowly bridge between inverter and battery (about 10-15 second). For details, just google it. If your battery has BMS (battery management system), you need to make sure its BMS limit is at least 120A; anything less, the battery won’t be able to support 1,500W @110V inverter load. During my test, I found out this inverter consumed between 2.20 Watt and 2.31 Watt of my 12V battery (at idle, inverter “ON” without pulling any load). For this type of inverter is acceptable; to save battery power, just turn it OFF when not in use. There is discrepancy of output Voltage reading between my Fluke meter and inverter display (ranging from 1.5V to 0.5V). First test, I used a portable heater rated for 1,500W @110V. My heater only pulled 11.6A @111V - equivalent to 1,288Watt (according to the inverter meter). My next test is adding more load to the existing load. Total load was about 14.1Amp at 110V - equivalent to 1,551Watt (according to the inverter meter). I had it run for about 10 minutes and worked fine. The product information states the inverter peak power is 1,700Watt. To obtain longer life of the inverter, it is recommended to run below rated (1,500Watt) for continuous usage. For appliance usage, you may need bigger inverter due to initial power surge, the initial surge can be 50%-60% more of the rated appliance. PS: I did test both USB ports, and they all worked fine. See pictures for details. It is recommended to add fuse between 12V battery and the inverter (at the positive side), the max fuse for 2AWG (or 1/0) wire is 150A, with max wire length 2 ft for each terminal (positive/negative). The fuse is to protect the wire/equipment. Hope this info helps.

It ran my 1500W-ish heater just fine.... At least for a couple minutes... It started my sho vac (6hp?) It did struggle to start my circular saw though.. It took a couple pulls of the trigger.. But it eventually started it up. Over all I'm pretty satisfied with it! Just make sure you have a battery that can supply the current needed at it's maximum rating. Standby current was under 2A (less than 24W) The display take a little while to catch up when a load is applied. From the display it looks like my heater was pulling ~1250W with a DC current of 126A!! That's 1450W from the battery. Now I didn't measure the accuracy of the meters on the unit. so these numbers might be a little off.
