CEENR® USB-C Charger Adapter for Milwaukee M18 18V Batteries — 45W Power Bank

Milwaukee M18 5-cell lithium-ion slide batteries from 1.5Ah to 8.0Ah, OEM or CEENR — including the 48-11-1815, 48-11-1820, 48-11-1828, 48-11-1840, 48-11-1850, 48-11-1860. It isn't for LiFePO4 or 3- or 4-cell packs.

Phones, tablets, headlamps, GPS units and USB-C laptops. The 45W USB-C Power Delivery port (5/9/12/15V at 3A, 20V at 2.25A) and the 5V/2.2A USB-A port charge two devices at once, with PD, QC, AFC, FCP, SCP and Apple 2.4A fast-charge support. The bigger the pack you clip it on, the more charges you get.

Yes. The USB-C port is two-way: plug in a compatible USB-C PD phone or laptop charger — or a car adapter or power station with USB-C PD — and it recharges the pack it's clipped onto, so you don't need a tool charger on the road.

While it powers your devices, three LEDs mean 66–100%, two mean 33–66%, one means 1–33%, and a blinking first LED means the pack is low. While the pack recharges, the next LED blinks as it fills, and all three stay on at 100%. Press the button to turn the built-in LED work light on or off.

Unclip it when you're not using it, so it doesn't slowly drain the pack on standby, and let a pack cool after heavy high-current use before you recharge it.

No. CEENR is an independent brand. This adapter is engineered by CEENR to work with Milwaukee M18 batteries — it is not made by, sold by, or affiliated with Milwaukee. Milwaukee is a trademark of its owner, used here only to indicate compatibility.

Not automatically. Under the U.S. Magnuson–Moss Warranty Act, a tool maker generally can't make warranty coverage conditional on using its own brand of accessory, but it can decline a repair for damage a third-party product caused, and some tool warranties exclude damage from incompatible parts or accessories.
