12.6V 1A power adapter for 3-string lithium packs

This Dell-branded supply delivers 12.6V at 1A through a 5.5mm by 2.5mm barrel plug. It accepts 100-240V AC input at 50 or 60Hz and is intended for 11.1V or 12.6V lithium battery packs. The unit weighs .068 kilograms and includes a 92cm cord.

Verify device socket, polarity

Confirm the equipment uses a 5.5mm outer by 2.5mm inner barrel jack with centre-positive wiring. The adapter also fits 5.5mm by 2.1mm sockets. Ensure the device draws no more than 80% of the 1A rating to avoid triggering over-current protection. Check that the required voltage matches the 12.6V DC output.

Black plastic housing with LED status indicator

The corded electric design uses a black plastic jacket and male barrel connectors at both ends. A built-in LED shows green at no load, red during constant-current charging and green again once the pack reaches 90-95% capacity. Flashing red signals a protection event such as short circuit or overload; unplug immediately if this occurs.

Questions about this item

What comes in the package and do I need any extra cables?

The box contains one power adapter with a 92 cm AC cord and a 5.5 mm × 2.5 mm DC plug; no additional cables are required.

Should I choose the 5.5 mm × 2.5 mm plug or the 5.5 mm × 2.1 mm option?

The adapter ships with a 5.5 mm × 2.5 mm barrel connector that also fits 5.5 mm × 2.1 mm sockets, so a single version covers both sizes.

What does the 12.6 V 1 A rating mean when I connect it to my device?

It delivers up to 12.6 V DC at 1 A maximum; the maker recommends staying below 80 % of that load and the LED shows green at no load, red during constant-current charging, then green again above 90 % battery.
