Description

Is this pure sine wave output really necessary? What's the advantage over a cheaper modified sine wave inverter? Yes, it's essential for sensitive electronics like laptops, medical devices (CPAP), phones. Pure sine wave provides clean, stable power like your home outlets, preventing damage and ensuring optimal performance. Modified sine wave can harm devices. I have several DeWalt 20V batteries. How does using two at once work, and how much extra runtime does it provide? Using two DeWalt 20V batteries simultaneously doubles your runtime. The inverter draws power from both, extending operation time significantly for long trips or outages. It also works perfectly with just one battery. Can it truly power all my devices at once with its 550W rating? Yes. The 550W output and multiple ports (2 AC, 1 USB-C, 2 USB-A) can power a laptop on AC, while fast-charging phones and tablets via USB. Perfect for running and charging multiple small devices at once. What safety features are built into the inverter to protect my expensive DeWalt batteries and my devices? It features full protection: High/Low Voltage Cutoff for your DeWalt batteries, plus Over-Current, Over-Load, Over-Temperature, and Short-Circuit Protection. This ensures complete safety for your batteries and connected devices. How portable is it, and how bright is the built-in LED light for emergency use? Extremely portable at only 2 lbs with a handy carry handle. The built-in 600-lumen LED is very bright, perfect for lighting up a campsite, emergency blackout, or roadside repair.

Worth the money.

Works better than expected. I used it for running a tabletop pellet grill, electric cooler, charge electric scooters.

Awesome product!
Size: 550W Color: Yellow
Works great. I use 2x 4AH batteries and it runs my phone charger and rope lights for hours! Works as good if not better than my small Jackery. I am going to buy a second one to use in my storage container.

Length of time
Size: 550W Color: Yellow
Doesn’t deliver voltage for extended time. Had two batteries in 8.5 and 4. Tested using a fan pulling 60 watts. Lasted 20 minutes.

just okay
Size: 550W Color: Yellow
This device is acceptable; it accepts Dewalt batteries and converts the stored energy into AC power. It is quite impressive, especially when immediate power is required while on the move. However, it is limited by the necessity of having a substantial number of Dewalt batteries.

Doesn't fit 12ah batteries
Size: 550W Color: Red
Seemed nice, but would not fit 2 forge 8ah, 12ah or HD12ah at the same time. Making it useless for me.

2/5 Stars. Buyers Beware – Great Idea, Poor Execution
Size: 550W Color: Red
I was genuinely excited to get this inverter and turn my Milwaukee M18 batteries into a portable power station—but unfortunately, it didn’t live up to expectations. First off, I’m not even sure if this seller is the original manufacturer. There are multiple listings on Amazon with what appears to be the exact same unit, just rebranded. That already made me a bit skeptical, and after using it, I can see why. The biggest issue is the battery compatibility and design. I specifically wanted to run dual Forge batteries (like 12Ah or 8Ah), and it simply doesn’t work. The frustrating part is that it’s so close to working—it honestly feels like if they had spent an extra 10–15 minutes refining the spacing and slot positioning, it could have supported larger batteries without issue. Even trying to compromise didn’t help: - It won’t fit 2x Forge batteries (12Ah or 8Ah) - It won’t even fit 2x 8Ah Forge batteries For the price, that’s a huge letdown. On top of that: - The weight distribution feels off - The unit is noticeably loud during operation - Overall build feels like it missed some basic real-world testing At this price point, I expected a lot more flexibility and refinement. Right now, I’m honestly debating returning it. If they offered a full refund, I might keep it for light or occasional use—but as it stands, it’s hard to justify the cost. Battery Compatibility (Tested): Does NOT Fit 👎🏼 - 12Ah Forge + any Forge battery - 8Ah Forge + any Forge battery Fits 👍🏼 - 12Ah Forge + 5Ah battery - 8Ah Forge + 5Ah battery - 6Ah or 8Ah High Output + 5Ah battery - 2x 6Ah/8Ah High Output batteries - 2x 5Ah batteries Final Thoughts: This could have been an awesome product, but poor design choices really hold it back. If you’re planning to use larger Forge batteries, look elsewhere ... show more
