8.4V 2A Lithium Charger

This ABLEGRID AC power supply delivers 8.4V DC at 2A for 2S lithium-ion and LiPo battery packs. It accepts worldwide AC input from 100-240V at 50-60Hz and uses a barrel tip connector. The unit includes over-voltage and over-heat protection and carries CE, FCC and RoHS certification.

Replaces Lost or Damaged OEM Adapters

The charger serves as a direct 101% compatible replacement when the original adapter is missing or faulty. The jump is worth it when the existing supply no longer regulates voltage correctly or the tip no longer seats securely. Verify the DC output and barrel tip dimensions match the device before ordering.

Fits Portable and UPS Battery Packs

The adapter plugs into any standard wall outlet and connects to the battery pack via its barrel tip. It frees the pack from reliance on proprietary docks or USB charging circuits that may not support the required voltage. Ensure adequate ventilation during extended charging sessions and discontinue use if abnormal heat occurs.

Questions about this item

What barrel-tip size does the 8.4 V charger need to fit my device?

The adapter uses a barrel tip; verify the exact inner and outer diameter against your equipment before ordering.

Which way round does the centre pin go when I plug the barrel tip in?

Match the polarity symbol on the charger label to the device socket — centre positive is typical but not guaranteed.

When should I replace the 8.4 V 2 A power supply?

Replace it if the housing cracks, the cable frays, the unit becomes unusually hot, or output voltage drifts from 8.4 V.
