DeWalt replaced my power tool battery with a USB-C . given the power of

Your leaf blower battery should be able to charge the laptop. Your drill battery should charge your phone. And while we’re at it, why shouldn’t our ever-more-powerful USB-C power adapter be able to charge those power tool batteries, too?

Basically, there’s not much difference between the battery bank you buy from Anker and the power tool battery from DeWalt – they both generally have identical 18650 lithium-ion cells. But to do it all, your power tool batteries will need a powerful USB-C port.

And that hasn’t really been a thing until now.

The $100 DeWalt DCB094 USB Charging Kit lets you connect that port to any DeWalt 20V power tool battery in a literal snap. Slide this quarter-pound adapter onto your battery pack, and you’ll get a bi-directional 100W USB-C PD port. This means that not only can you charge a MacBook Pro-sized laptop with a larger DeWalt pack, you can also charge those DeWalt packs with your laptop or phone’s USB-C charger.

The adapter supports everything from cheap 1.3Ah packs to the massive 15Ah FlexVolt packs with your Los-Leader combo kit that you’ll probably only stick with in stationary devices. It’s the biggest gadget charging battery you’re liable to find outside dedicated power stations.

As someone with a garage drawer full of DeWalt batteries, I couldn’t wait to put it to the test. but it is not Fully The experience I’ve been dreaming of.

How we evaluate and review equipment

I’ve been testing the DeWalt DCB094 on and off for months, and this is the good news: it works perfectly.

I converted DeWalt’s monster 15Ah pack to a USB-C external battery that was able to charge my wife’s 14-inch MacBook Pro (69.6Wh) three times and still had gas in the tank. My Steam Deck? I charged its 40.04Wh pack a full five times – that’s 10 extra hours elden ring right there. When I filmed a timelapse Lego build of about three hours with my iPhone, I plugged it into the 6Ah DeWalt pack knowing there was off course not My juice will run out.

You get a 100W USB-C PD port and a 12W USB-A port. The USB-A port will do passthrough charging, even when you’re charging the DeWalt battery.

Every DeWalt 20V battery I tried, new or old, big or small, worked with the adapter as well. This includes my two 1.5Ah packs, one 1.7Ah pack, two 5Ah packs that came with my lawnmower, and two 6Ah packs I bought about a year ago and rarely use. I’ve seen them all charge up to 100W in both directions over that USB-C port, which is enough to keep most of today’s (but not tomorrow’s) biggest USB-C PD laptops running just like they’re plugged into the wall. were done.

When it came time to recharge those power tool batteries, the 100W USB-C port sometimes let me do it faster than DeWalt’s AC adapter. While DeWalt unfortunately only ships the DCB094 with a 65W USB-C charger, even that should offer a faster charging rate than the company’s cheaper AC adapters that come with drills or driver kits. And when I added my separately purchased 100W USB-C charger, I was able to get more time out of my 4A (80W) DeWalt AC adapter when charging the largest pack.

Here’s how fast these batteries can be charged and roughly how much of them I got:

* It may be more efficient to charge a larger battery for a longer period of time. With a 15Ah DeWalt battery, I saw a 69.6Wh MacBook Pro charging closer to 224Wh, and charging a 100Wh USB-C battery bank closer to 240Wh.

The only issue I had was if I completely drained the battery, and I mean Completely Drained it – ran it all the way down into a leaf blower or drilled repeatedly until it spun no more – sometimes when I popped it the devolt adapter wouldn’t light up for charging. Sometimes I had to dodge it by plugging it into a different battery or charger first. Oh, and you can’t charge one DeWalt battery with another DeWalt battery using two adapters. I tried.

So if it works beautifully to an extent, why am I giving it a 6 to this product? partly because ledge The review score has just been moved to a full 10-point scale to avoid score inflation – a 6 is still good! — but also partly because the benefits of the DeWalt adapter start to diminish when you No Pairing this with a 15Ah battery that costs $389.

Every battery I’ve tried works – even a Chinese knockoff – but not all batteries are created equal. I wouldn’t bother using a smaller 1.5Ah battery. Nor knock, because the seller lied about his ability.

With smaller batteries like my 1.5A, 1.7A and even 4Ah packs, they didn’t charge needy devices long enough to justify reaching for them on a traditional battery bank or charger.

Part of this may be due to transfer losses, which are not unique to DeWalt. You can’t fully charge a 100Wh laptop battery with a 100Wh battery pack like DeWalt’s DCB205 because some of that energy doesn’t get past it. (Some gets spent as heat, and I can attest that charging my 100Wh HyperJuice with a DeWalt adapter leaves the HyperJuice uncomfortably hot to the touch.) In general, I’ve used my gadgets. saw losses of between 20 percent to 33 percent with – for example, the 6Ah (120Wh) DCB206 only gave me 80Wh worth of Steam Deck battery life.

But the 6Ah battery is also a 2.5-pound brick when you add the DeWalt adapter—twice the weight of my HyperJuice, even if we’re assuming I don’t need to buy a DeWalt battery because I already have my tools. is one for. The DeWalt’s 5Ah battery is only slightly lighter, but then I’m only looking at 66Wh of power for my gadgets, and so on.

When you consider the fact that DeWalt batteries are quite expensive and heavy for the capacity they typically offer, I can’t really recommend anyone buying into the DeWalt ecosystem for this feature , unless you really need to bumpy Batteries that can charge your devices And Power tools on the go.

but if you already Do you have a garage full of large amounts of DeWalt batteries that don’t get a lot of use? I could see myself spending $100 if I didn’t already have one or two capable power banks. Between the 5A charging speed and 100W output for the gadgets, there’s a lot to like.

The A port does 5 volts at 2.4 amps, the C port does 5 to 15 volts at 3A, or 20V at 5A.

Zoom in for charging specs.

Now, though, I really want to take the obvious next step for DeWalt and company: stick the USB-C port on the battery itself, so we don’t have to mess with the adapter. In January, DeWalt product manager Sean Fitzgibbons told me that the DCB094 could be a test balloon: “If we get the interest I expect we’re going to get, I think it’s worth adding to the potential.” That will open the door for the battery directly down the road.”

I think DeWalt should be doing just that. Many people will buy a USB-C native power tool battery, never considering the $100 adapter you’ll have to turn on and off every time.
