350W Inverter for Milwaukee 18V Li-ion Battery, 4-Port 20V to 120V Pure Sine Wave Inverter with LED Light, 3 USB-A Port, 1 USB-C Port, 1 DC Port, Power Station for Outdoor Camping(No Battery)

Can use any combo of 1 to 4 batteries. If it doesnt detect all batteries it is because the unit will wait until voltages match across the packs. Batteries are hot swappable. AH do not need to match. Powering my tmobile home internet box... only 45 watts fyi. Unit can handle 350 watts

Yep, Sure does!!! I hooked up one of my dewalt 60 Volt 9 AH batteries and fired it up. Ran for over an hour and still had 3 out of 3 power bars remaining on the battery. Peak draw of around 150watts for roughly a minute than sustained draw of 10-40 watts for over an hour before i turned it off. (NOTE: It only ran at 20 volts not 60 volts as designed by battery manufacturer). Next day I put 4 batteries on it that were rated at 20 volt 3 AH each and ran it for around 8 hours before it drained them down to where the inverter quit! I'm quite impressed as the weight if the inverter and the batteries combined is about half of the weight of another power inverter with the same 300 watt rating I also tried, that couldn't handle the startup load. Also at 1/3 of the cost but I do need to mention I already had the batteries so not a real comparison as those cost more than the inverter as you already know if your buying this tool. welp lets try something else!

Very good, can hot swap batteries and can is pure sine. Good value, compared to the 500$ Milwaukee one.

this will not charge your batteries only works with charged batteries . it works but have not used it much . but so far so good

So now you have an electric lawn mower. Suddenly your electricity goes out, and you’re sitting in the dark. Hey you have plenty of electricity sitting on your mower. Where do you plug in your phone? Well that’s where this inverter comes in handy. Phone and small device charging works very well. There’s a 350 watt AC inverter here for light duty AC use. You can’t run a 1500 watt hair dryer, sorry to disappoint, but a low wattage power brick works great. Portability is nice as long as you even the load with your batteries plugged in on both sides of unit. I give it Five stars!

Works for its purpose, but it cannot charge batteries. This kind of makes it useless because you have to make sure all the batteries are charged before it’s functional. It would make more sense to be able to simultaneously charge batteries and use as a power bank. I returned it, but if it would have charged batteries, I wouldn’t have.

Love this thing. Haven't had any problems with it. I used it to run a stereo as a receiver at the drive in It also runs a TV in my shop. If I have a power outage, we will see if it can run a fridge

Finally got a chance to try it. It failed. It would not even run a small tv.
