Power Tool Battery Becomes Powerbank

A $100 adapter turns a DeWalt power tool battery into a powerbank for charging most devices. An early review suggests it works well, though is clearly a very niche use scenario.

The USB-C adapter clips on to any 20V power tool battery and then offers two-way charging at 100w: in other words, you can plug a device in to the battery to charge or plug the battery into an outlet with a USB power cable. The device also has passthrough charging. The concept makes sense, though it’s really limited to a specific scenario: you already have a DeWalt battery available and you’re looking for an extremely high capacity portable powerbank.

The Verge’s Sean Hollister has tested it extensively and says it works as advertised, with the 15Ah DeWalt able to charge a MacBook Pro three times and still have spare capacity. He also noted it worked with some off-brand batteries that advertise DeWalt compatibility.

However, he did find the 15Ah battery was the only capacity where the benefits outweighed both the financial cost and the added weight compared to a traditional powerbank.

DeWalt says it will study interest in the adapter and decide whether to build a USB port directly into its batteries in future.

Editor’s note: You can get a 30,000 mAh battery for about $30 to $50 on Amazon nowadays, so I’m not sure why someone would pay $100 for an adapter that goes on separate battery.

Real Engineering and SpinLaunch: Can We Throw Satellites to Space?

From Real Engineering:

This has been in the works for about 3 months now. Our first full documentary shoot. There is a lot of negativity in the comments from people who have not even watched the video yet. This channel is about being positive about engineering. Encouraging and inspiring the next generation of engineers. If you are looking for a channel that focuses on being negative and adds nothing to world, you have come to the wrong place. It’s so much easier to point out what’s hard, than using your brain to think of solutions. That’s not what engineers do. We find problems, and then we find solutions. If you don’t think a company that’s trying to throw satellites into space, and has already built a 1/3rd prototype, isn’t insanely cool. I don’t know what to do for ye. That’s badass. Whether they succeed or not is irrelevant. It’s not your investment money they are using, chill out.
