The ADADP05 transforms any Makita 18V LXT battery into a portable USB charging station, solving a real problem contractors face daily — keeping phones and tablets charged at remote jobsites. At 0.4 lbs, it’s light enough to forget it’s clipped to your belt until you need it.
Worth it for crews working backcountry construction or anyone who burns through phone batteries coordinating jobs. Skip it if you’re always near truck power or already invested in dedicated power banks.
USB Power Output That Actually Matters
The dual USB-A ports deliver 2.1A each, or 4.2A total when both ports are connected. That’s enough juice to charge two phones simultaneously at decent speeds, though not the rapid charging you’d get from newer USB-C power delivery systems.
| Specification | Value |
|---|---|
| USB Output Per Port | 2.1A (5V) |
| Total USB Output | 4.2A (when both ports connected) |
| Port Type | USB-A |
| Number of Ports | 2 |
| Weight | 0.4 lbs |
The 2.1A per port lands in the sweet spot for most jobsite needs. It’ll charge an iPhone or Android in about 90 minutes, or keep a tablet topped off while you’re checking plans. Sure, modern fast-charging standards blow past these speeds, but those require USB-C ports and compatible devices. For the USB-A cables everyone still carries, this delivers solid performance.
Built for Montana Jobsites
Rubber port covers protect USB ports from dust and water — the kind of simple feature that matters when you’re framing in a dust storm or working through spring rain. The covers snap tight enough to keep sawdust out of the ports but pop open easily with gloved hands.
The Outdoor Adventure camo-green design isn’t just cosmetic. Provides 4.2A total output (2.1A per port), which may be higher than early versions of the standard ADP05. The real upgrade over the standard blue version is those rubber port covers for better protection against elements.
Built-in belt clip for attachment to belt or holster keeps it accessible without taking up pocket space. The clip holds tight — won’t pop off when you’re climbing scaffolding or squeezing through tight spaces.
LXT Battery Platform Integration
Compatible with all Makita 18V LXT Lithium-Ion batteries (from 1.5Ah to 6.0Ah). Not compatible with G-Series or CXT batteries. If you’re already running Makita tools, you’ve got power sources sitting in your truck right now.
The math on runtime is straightforward. A 5.0Ah battery theoretically provides about 90 watt-hours. At maximum 4.2A draw (21 watts), you’re looking at 4+ hours of continuous charging. Real-world usage where phones cycle between charging and maintaining gives you all-day power from a single battery.
Slide the Makita 18V LXT battery onto the bottom of the ADADP05 power source until it clicks. Toggle the on/off switch on the side to activate power output. Plug USB cables into the ports under the rubber covers. That’s it. No pairing, no apps, no complexity.
The Verdict
3-year limited warranty covering defects in materials and workmanship backs up Makita’s build quality claims. At 4.7 out of 5 stars (based on retailer listings), users consistently praise the portability and reliability.
The ADADP05 makes sense for contractors already invested in the LXT platform who need reliable USB power away from the truck. Those rubber port covers earn their keep on dusty jobsites. The 2.1A charging speed won’t win any races, but it’s fast enough for practical use.
The lack of USB-C limits future compatibility, and dedicated power banks offer more capacity per battery. But for turning idle batteries into charging stations, this adapter delivers exactly what it promises.
Frequently Asked Questions
Q: Can I leave the ADADP05 connected to a battery overnight?
On/Off switch for operator convenience means you control when it draws power. Turn it off when not in use to preserve battery life. The unit itself won’t overcharge your devices — that protection is built into modern phones and tablets.
Q: Will this work with my 12V CXT compact batteries?
No. Not compatible with G-Series or CXT batteries. This adapter only works with the 18V LXT slide-style batteries.
Q: How does the camo version compare to the standard blue ADP05?
ADADP05 features a camo-green color for outdoor styling. ADADP05 includes rubber port covers for better protection against elements. Provides 4.2A total output (2.1A per port), which may be higher than early versions of the standard ADP05. For jobsite use, those rubber covers make the camo version worth considering.
Q: Can this charge a laptop?
Not effectively. 2.1A output per USB-A port delivers about 10.5 watts — enough for phones and tablets but far short of what most laptops need. Even if your laptop accepts USB-A charging, it would charge extremely slowly if at all.
