Awesome Product

You will not regret buying one of these. I’m working on a portable entertainment system and I needed an inverter that is reliable and this did not disappoint. It’s super reliable, especially when the power went out in my area for a few hours while I was at work - it’s so easy to understand my wife was able to use it until the power came back on. Definitely felt the need to buy the 1000W after that!

This inverter rocks.. very underrated..

We are running our Coffee maker running off of this every morning for our remote job site crews. AMP meter shows the c-maker is pulling a consistent 663 watts and and the cooling fans do not even engage. We are using two 9amp/hr flexvolt batteries and this setup is very efficient. GREAT product!!!!

That is great to hear, Tim! I love to hear about these devices being used by tradesmen on job sites. Great way to get even more use out of your batteries.

Well Built Inverter

This thing is great for a weekend camping trip. Built like a tank. I've got two 10ah and one 5ah DeWalt 20v batteries and was able to run two small fans to sleep with over two nights with battery left to spare. The safety margin for the batteries is more than I thought, which is good for the batteries but they did run down quicker than I thought they would based off the calculator I used. I also wish I could turn off the alarm, might try to open it up and remove the speaker if possible.


Live it! Works as advertised.

Great 3rd party tool for Dewalt batteries

I've been using this unit on and off for the past 6 or so months to charge laptops and power other devices out on my property without having to use an extension cord. I purchased it for power outage use, but fortunately haven't had to use it yet.

The device itself is great, showing you the current frequency and battery voltage, which you can roughly equate to remaining runtime if you have some electrical knowledge. It's beefy enough to run my refrigerator even during startup with 2x 6Ah flexvolt batteries. The hot swappable nature of using 2 batteries in parallel is awesome so there's no electrical disconnection if you're powering a TV, modem, or other device that would be annoying to disconnect momentarily.

Kudos to Miller Tech for bringing this product to market, a great use for Dewalt (and other) batteries.
