  • Battery powered inverter ideal for many occasions
Style: No Battery For Dewalt 20V
This review is on the power inverter from VoLtTech. The photos show details of this inverter after removing it from the package and using for charging a variety of devices. The listing gives a good description of the features and specifications of this inverter. I found it to be a well made product with no visual flaws or operational issues. It uses Dewalt 20 volt batteries for a power source which is not included and you must supply. The inverter itself has two 110 outlets and two USB type A outlets while the Dewalt battery adapter has one USB A and one USB C outlets. All the USB outlets are powered when the battery is connected, the 110 outlets are powered when the switch is turned on. You can see in the photos I connected a multitude of devices for charging. It did an excellent job of charging them and I didn’t experience any overheating from the inverter. The devices all charged at the same rate as they do when I charge them individually. I don’t have a device or meter to test the maximum output, but in my opinion I think it’s safe to say that using something that draws as much wattage as this unit is capable of might possibly exceed the capacity of the inverter. At least I’ve found using devices that stay below the rated capacity of inverters will prevent problems. This inverter is perfect for what the the listing states, low power devices. It’s a great power source for travel, camping, outdoor activities, emergency situations, etc. This Dewalt 20 volt battery powered inverter from VoLtTech worked very well for me and I recommend it! ... show more

  • VoLtTech 300W Power Inverter: A Handy Solution with Some Quirks
Style: No Battery For Milwaukee 18V
The VoLtTech 300W Power Inverter caught my attention as a potential solution for powering devices in my 2006 sedan, which isn't exactly known for its electrical capabilities, especially when connecting modern accessories. The product listing was a bit confusing; it initially indicated compatibility with DeWalt batteries clearly pictured when I purchased it; but later displayed a picture and description for a Milwaukee item when it came time for review. After further reading, I learned that the inverter is designed to work with both brands, depending on the model selected. I'm curious whether the same model is used to accommodate both DeWalt and Milwaukee batteries, with only the color of the unit differing. Physically, the inverter feels sturdy and well-built. However, inserting the DeWalt 20V battery into the model I received (which was painted red) required more force than I expected, which was concerning at first. A quick tap on the counter helped seat the battery properly, and once connected, the inverter functioned as intended. It powered my laptop and charged my phone without any issues. So far, I find VoLtTech's inverter to be generally reliable and capable of handling various devices, making it useful for camping or as a backup power source. While the inverter can be a bit finicky with certain battery fits, this has aligned with my experience. The VoLtTech 300W Power Inverter serves its purpose well, especially for those needing a portable power solution compatible with DeWalt or Milwaukee batteries.

  • perfect for powering my miniature portable projector!
Style: No Battery For Milwaukee 18V
I recently added this 300W power inverter to my toolkit, designed specifically for Milwaukee M18 batteries, and it's been a game-changer. As someone who often works remotely or in areas without easy access to power outlets, this inverter provides a reliable solution to keep my devices charged and operational. The inverter features two AC outlets, allowing me to plug in tools or devices that require standard power, and two USB ports for charging phones, tablets, or other electronics. The setup is straightforward—just slide in the M18 battery, and you're ready to go. One of the standout features is its portability. The compact design makes it easy to carry around, and the build quality feels robust enough to withstand the rigors of daily use. Whether I'm on a job site or camping, this inverter ensures I have the power I need without being tethered to a wall outlet. Overall, I highly recommend this inverter to anyone who uses Milwaukee M18 batteries and needs a portable power solution. It's efficient, easy to use, and has become an indispensable part of my gear. ... show more

  • Doesn't put out consistent higher power as rated....
Style: No Battery For Dewalt 20V
Just arrived and I had high hopes for this. I wanted to see if it would provide reasonably high power based on its 300 Watt rating. I attempted to run a mid-sized fan on it. I initially tested the fan directly on a good outlet with a wattmeter. The fan draws 210 watts consistently. I connected a freshly charged 20V 5AH Dewalt battery to the device. I connected the fan and noticed it ran but sounded a little slow. I checked the output of the inverter with the same wattmeter and found the inverter was only supplying 170 Watts. I thought it might be the battery, so I changed it out. I connected a brand-new Dewalt 60/20V 10AH battery and retested it. The inverter still only provided 170 Watts again. It appears the device does not handle a moderate load very well at all. I am sure it will operate smaller loads just fine as I also tested a laptop charger of 65 Watts and it was fine. I would only recommend this device for use with smaller loads of about 100 Watts or less. Clearly nothing very substantial. I will keep this as a backup for camping for powering smaller loads only. ... show more

  • High Quality.
Style: No Battery For Dewalt 20V
I tested this out on several 110 devices and it's awesome. Better than a couple of Cheaper inverters that I've tried.

  • So handy!
Style: No Battery For Dewalt 20V
This inverter is incredibly handy for on-the-go power using Dewalt batteries. I used it to run a fan and charge my phone during a camping trip, and it worked flawlessly. The dual AC outlets and USB ports make it super versatile. Just remember, it doesn’t include the battery, but it’s a great companion if you already own Dewalt 20V tools. ... show more
