Your leaf blower battery ought to have the ability to cost a laptop computer. Your drill battery ought to cost your cellphone. And whereas we’re at it, why shouldn’t our ever-more highly effective USB-C energy adapters have the ability to cost these energy instrument batteries as nicely?

Essentially, there’s not a lot distinction between a battery financial institution you purchase from Anker and an influence instrument battery from DeWalt — each typically comprise the identical 18650 lithium-ion cells. However to do all that, your energy instrument batteries would wish a robust USB-C port.

And that hasn’t actually been a factor… until now.

The $100 DeWalt DCB094 USB Charging Package allows you to add that port to any DeWalt 20V energy instrument battery in a literal snap. Slide this quarter-pound adapter onto your battery pack, and also you get a bi-directional 100W USB-C PD port. Meaning not solely are you able to cost as much as a MacBook Professional-sized laptop computer with a sufficiently big DeWalt pack, you may cost these DeWalt packs along with your laptop computer or cellphone’s USB-C charger as nicely.

The adapter helps the whole lot from a budget 1.3Ah packs that got here along with your loss-leader combo package to the huge 15Ah FlexVolt packs you’d in all probability solely stick in stationary instruments. It’s the largest gadget charging battery you’re liable to seek out exterior of devoted energy stations.

As somebody with a storage drawer filled with DeWalt batteries, I couldn’t wait to place it to the take a look at. But it surely’s additionally not fairly the expertise I used to be dreaming of.

How we fee and evaluation units

I’ve been testing the DeWalt DCB094 on and off for months, and right here’s the excellent news: it completely works.

I turned DeWalt’s monster 15Ah pack right into a USB-C exterior battery that was capable of cost my spouse’s 14-inch MacBook Professional (69.6Wh) three full instances and nonetheless had fuel within the tank. My Steam Deck? I charged up its 40.04Wh pack 5 full instances — that’s 10 additional hours of Elden Ring proper there. After I filmed a virtually three-hour timelapse Lego construct with my iPhone, I plugged it right into a 6Ah DeWalt pack figuring out there was no method I’d run out of juice.

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

Each DeWalt 20V battery I attempted, new or previous, giant or small, labored with the adapter, too. That features my two 1.5Ah packs, one 1.7Ah pack, the 2 5Ah packs that got here with my lawnmower, and the 2 6Ah packs I purchased a few yr in the past and infrequently use. I clocked all of them charging as much as 100W in each instructions over that USB-C port, sufficient to maintain at this time’s (however not tomorrow’s) greatest USB-C PD laptops working similar to they had been plugged into the wall.

When it got here time to recharge these energy instrument batteries, the 100W USB-C port generally let me do it quicker than DeWalt’s AC adapters, too. Whereas DeWalt sadly solely ships the DCB094 with a 65W USB-C charger, even that ought to supply a quicker charging fee than the corporate’s cheaper AC adapters that include drill or driver kits. And after I added my very own individually bought 100W USB-C charger, I used to be capable of shave off time over my 4A (80W) DeWalt AC adapter when charging the very greatest packs.

Right here’s how briskly I obtained these batteries to cost and roughly how a lot I obtained out of them:

Cost instances and capacities

DeWalt battery Battery situation 65W USB-C charger + adapter 100W USB-C charger + adapter 4A DeWalt wall charger (DCB115) Steam Deck cost from DeWalt battery*
DeWalt battery Battery situation 65W USB-C charger + adapter 100W USB-C charger + adapter 4A DeWalt wall charger (DCB115) Steam Deck cost from DeWalt battery*
1.5Ah (30Wh) Reasonably used 26 minutes 27 minutes 22 minutes 21Wh (half cost)
1.7Ah (34Wh) Model new half-hour 26 minutes 26 minutes 22.8Wh (half cost)
4.0Ah (80Wh) Closely used 55 minutes 51 minutes 47 minutes 48Wh (1 cost)
5Ah (100Wh) Reasonably used 1h, 29m 1h, 5m 1h, 14m 66Wh (1.5 costs)
6Ah (120Wh) Evenly used 1h, 47m 1h, 24m 1h, 29m 84Wh (2 costs)
15Ah (300Wh) Model new 4h, 33m 3h, 14m 4h, 6m 206Wh (5 costs)

*Charging bigger batteries for longer could also be extra environment friendly. With 15Ah DeWalt battery, I noticed nearer to 224Wh charging a 69.6Wh MacBook Professional, and nearer to 240Wh charging a 100Wh USB-C battery financial institution.

The one subject I had was that if I totally drained a battery, and I imply totally drained it — ran all of it the best way down in a leaf blower or drill repeatedly till it might spin no extra — generally the DeWalt adapter wouldn’t mild as much as cost after I popped it on. Generally I needed to trick it by plugging it into a special battery or charger first.

So if all of it works so fantastically, why am I giving it this product a 6? Partly as a result of The Verge simply moved to a full 10-point scale for evaluation scores to keep away from rating inflation — a 6 remains to be good! — but additionally partly as a result of the DeWalt adapter’s benefits start to recede if you’re not pairing it with a 15Ah battery that prices $389 all by itself.

Each battery I attempted works — even a Chinese language knockoff — however not all batteries are equal. I wouldn’t trouble utilizing a tiny 1.5Ah battery. Nor the knockoff, as a result of the vendor lied about its capability.

With smaller batteries like my 1.5A, 1.7A and even 4Ah packs, they merely didn’t cost needy units lengthy sufficient to justify reaching for them over a standard battery financial institution or charger.

A part of that’s seemingly resulting from switch losses, which aren’t distinctive to DeWalt. You possibly can’t totally cost a 100Wh laptop computer battery with a 100Wh battery pack like DeWalt’s DCB205 as a result of a few of that vitality doesn’t make it throughout. (Some will get expended as warmth, and I can attest that charging my 100Wh HyperJuice with the DeWalt adapter made the HyperJuice get uncomfortably sizzling to the contact.) Basically, I noticed losses of between 20 % and 33 % with my devices – for instance, the 6Ah (120Wh) DCB206 solely gave me 80Wh value of Steam Deck battery life.

You possibly can even cost your DeWalt batteries tremendous slowly with a 5V USB-A adapter in a pinch. It took 28.5 hours to prime up this 6Ah DeWalt battery.

However that 6Ah battery can also be a 2.5-pound brick when you add the DeWalt adapter — twice the load of my HyperJuice, even when we’re assuming I don’t have to purchase the DeWalt battery as a result of I have already got one for my instruments. DeWalt’s 5Ah battery is simply just a little lighter, however then I would solely be taking a look at 66Wh of energy for my devices, and so forth.

When you think about the truth that DeWalt’s batteries are fairly expensive and heavy for the capability they sometimes supply, I can’t actually advocate somebody purchase into the DeWalt ecosystem only for this function, except you actually need rugged batteries that may cost your units and energy instruments on the go.

However for those who already have a storage filled with sizeable DeWalt batteries that don’t get quite a lot of use? I may completely see myself spending $100 if I didn’t have already got a succesful energy financial institution or two. Between the 5A charging speeds and the 100W output for devices, there’s so much to love.

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 the charging specs.

Now, although, what I really need is for DeWalt and firm to take the plain subsequent step: stick the USB-C port on the battery itself, so we don’t have to mess with adapters in any respect. In January, DeWalt product supervisor Sean Fitzgibbons advised me the DCB094 might be a little bit of a take a look at balloon: “If we get the curiosity that I anticipate we’re going to get, I believe that might open the door much more to doubtlessly including that on to batteries down the highway.”

I believe DeWalt ought to simply do it. Lots of people would purchase a USB-C native energy instrument battery who’d by no means think about a $100 adapter you’ve gotta tackle and off each time.
