DeWalt 10,000mAh 2 Port Powerbank

I tossed this DeWalt power bank into my bag for a couple of weeks of jobsite visits and travel to see if a rugged, IP-rated bank really adds value beyond the usual slim pocket bricks. Short answer: it does—provided you know what you’re buying and how you’ll use it.

Design and durability

This is very clearly built for rough environments. The exterior has a grippy, rubberized shell with enough structure to shrug off dings and scrapes. The integrated utility loop is not a gimmick; I clipped it to a tool bag and harness and didn’t think about it again. The port cover is the star: snap it shut and you get IP67 protection, meaning dust-tight and water-resistant to 1 meter for 30 minutes. That’s confidence you don’t get from most 10,000 mAh banks.

A couple of practical notes:
- The cover needs to be fully and firmly seated to maintain the seal. If you’re in the habit of half-closing flaps, retrain that habit here.
- At 0.79 lb, this isn’t ultralight. It’s still portable, but it’s more “bag” than “jeans pocket.”
- The footprint is larger than many 10k banks. On a narrow ladder top or crowded bench, it takes up space.

DeWalt includes a Kevlar-reinforced USB-C to USB-A cable. It’s tough and resisted kinks, which I appreciate. Just know that if you want the fastest recharge into the bank from a USB-C PD wall charger, you’ll want a USB-C to USB-C cable (not included).

Ports and charging performance

You get two outputs:
- USB-C with Power Delivery (PD)
- USB-A with Quick Charge (QC)

Both ports can be used at the same time. In practice, that meant I could fast-charge a phone on USB-C while topping off a headlamp or earbuds on USB-A without tripping any protection or watching speeds crater. With a modern smartphone, the USB-C PD port delivered the familiar fast-charge ramp from low battery up to around 70–80%, then tapered off as expected. I routinely saw my phone jump from roughly 20% to 80% in around 35–45 minutes, which is on par for 18–20W-class PD.

On the USB-A QC port, older devices that speak QC handshake charged briskly, and generic 5V devices charged normally. If your world is entirely USB-C now, you’ll still appreciate having the A port for legacy gear on the job.

Thermally, the bank gets warm under sustained high load, especially when running both ports at once, but never hit a level that concerned me. I kept it on a hard surface or clipped off a bag while charging, which is good practice with any lithium pack.

Battery life and recharge time

DeWalt lists 10,000 mAh (40 Wh). Real-world output is always lower than the label because of conversion losses. In my testing:
- Modern phones with 4,000–5,000 mAh batteries got roughly 1.5–2 full charges.
- Smaller phones and compact devices stretched closer to two-plus.

That lines up with expectations for a 10k pack. The LED charge indicators are basic but accurate enough: four bars, no percentage readout. After a few cycles, I had a good sense of how far each bar gets me.

Recharging the bank took about four hours from near empty using a capable USB-C PD wall charger. Using a weaker 5V/2A USB-A brick pushed that beyond five hours. If you’re turning this over daily, invest in a proper USB-C charger and a C-to-C cable to keep turnaround times reasonable.

Day-to-day usability

A few things stood out after carrying it through sawdust, a light rain, and a couple of flights:
- The port area has a bit of flex when plugging in, likely due to the sealed design and cover assembly. It never failed me, but I learned to support the body and insert cables straight on.
- The loop is genuinely useful. I clipped it out of harm’s way to avoid it getting buried under gear while charging.
- The matte exterior holds onto grime less than I expected and wipes down easily.
- The lack of an OLED percentage readout or extra ports keeps things simple. If you like lots of ports and screens, this isn’t that product.

As for travel, at 40 Wh it’s well below airline limits for carry-on lithium batteries. I had no issues through security.

Safety, heat, and IP67 realities

IP67 is a perk, but it only applies with the port cover fully closed and intact. If you work in rain or dust, treat the cover latch like a critical component: inspect it, keep the sealing surface clean, and don’t leave cables dangling with the flap open in messy conditions.

On thermal behavior, the pack warmed up during fast charging and when recharging itself—normal for lithium-ion. A few best practices I followed and recommend:
- Don’t charge the bank under bedding, inside a tool pile, or on soft, insulating surfaces.
- Use quality cables that aren’t frayed, with straight insertion and no excessive strain on the ports.
- If the pack is hot to the touch, give it airflow and let it cool before stowing.

These are general lithium safety habits, not unique to this model, but they matter on a jobsite where conditions are less controlled.

Value and who it’s for

There are plenty of 10,000 mAh PD banks in the $25–$35 range. This DeWalt typically costs more, and you’re paying for ruggedness, the IP67 rating, and a jobsite-first design with a tough cable and carry loop. If you’re rough on gear, work in dusty or wet environments, or want a power bank that can live in a tool bag without babying it, the premium makes sense.

If you’re a commuter or student who wants the slimmest, lightest pack with a digital display and more ports, you’ll find better value elsewhere. Likewise, if you need to fast-charge tablets at higher wattage or trickle a laptop, step up to a higher-capacity, higher-output bank.

What I’d change

• A firmer-feeling port frame would inspire more confidence when plugging and unplugging frequently.
• A USB-C to USB-C cable in the box would better match how most people will recharge the bank and use the PD port.
• A small percentage readout would be a nice quality-of-life upgrade for planning power on longer days.

None of these are deal-breakers, but they’d round out the experience.

The bottom line

The DeWalt 10k is a purpose-built power bank that trades pocketable sleekness for durability and environmental protection. In my use, it delivered reliable PD and QC charging, ran two devices without drama, shrugged off grime and a light soak, and recharged in about four hours with a proper wall charger. It’s heavier and bulkier than the typical 10,000 mAh brick, and the sealed port design introduces a bit of flex you’ll notice, but the overall package feels ready for real-world abuse.

Recommendation: I recommend this power bank for tradespeople, outdoor users, and anyone who needs a tough, IP67-rated charger that can live in a tool bag and keep phones, headlamps, earbuds, and small devices topped up. If your priorities are ultra-compact size, the lowest price, or laptop-level output, look to a slimmer consumer bank or a higher-capacity model instead. For its intended use—rugged, no-nonsense charging in challenging environments—it earns a spot in my kit.
