ABLEGRID 4S Lithium Charger

This ABLEGRID charger is built for 4S lithium-ion or lithium-polymer packs with nominal voltages of 14.4V or 14.8V and a full-charge target of 16.8V. It suits anyone who needs a direct wall-plug replacement for the original adapter supplied with a UPS or similar backup unit.

Sustained load behaviour

The unit accepts worldwide AC input from 100V to 240V at 50Hz or 60Hz and delivers a steady 1A DC output through a barrel tip. Built-in over-voltage and over-heat protection engage automatically during extended charging sessions, preventing damage to both the charger and the connected battery pack.

Pre-order checklist

Verify that your device requires exactly 16.8V DC at 1A and uses the same barrel connector dimensions before ordering. Ensure the charging location provides adequate ventilation and avoid placing the adapter on heat-sensitive surfaces during long charge cycles.

Questions about this item

Does the charger run hot or make noise when left plugged in all day?

It includes over-heat protection and operates from a 100-240 V AC supply at 50-60 Hz, so it stays cool and silent during continuous use.

What battery packs can I charge with this unit?

It is designed for 4S lithium-ion or LiPo packs with nominal voltages of 14.4 V or 14.8 V and a full-charge voltage of 16.8 V or 17 V, using the barrel-tip connector.

Will it work with my older 3S lithium packs?

No, the output is fixed for 4S chemistries at 14.4 V, 14.8 V, 16.8 V or 17 V and will not suit 3S packs.
