AC 100-240V universal input

The ABLEGRID charger accepts AC 100-240V at 50-60Hz for worldwide use and delivers DC 4.2V at 1A through a 3.5x1.35mm barrel tip. It is built for devices that require this exact voltage and connector size. Over-voltage and over-heat protection are integrated.

Replaces lost or faulty 4.2V 1A adapters

This unit replaces an original charger only when the device demands DC 4.2V, 1A and a 3.5x1.35mm barrel connector. The jump is worth it when the original supply is missing, damaged or no longer holds regulation. It is not for equipment needing a different voltage, current or tip diameter.

Fits into a build as a direct power source

The adapter plugs into any AC 100-240V outlet and connects directly to the device’s DC jack, freeing the system from reliance on USB power or proprietary docks. It needs no extra cables beyond the fixed barrel lead. Buyers who need a different connector or higher current cannot use this model.
