Faster recharges - thanks to per-slot rapid charging
A four-bay rapid charger controls charge current per slot and monitors each battery individually, allowing the stated charge times for AA and AAA cells. Charging switches to trickle mode when a cell reaches full capacity to prevent overcharge.
Get usable batteries quickly for remotes, toys and cameras; two AA reach charge in about 3.5 hours. Full sets of four AA or four AAA complete within the advertised times.
Clear status feedback - with multi-mode LED indicators
LEDs blink slowly while charging, show solid white when a battery is fully charged, and blink fast to indicate an error such as a defective or alkaline cell. All LEDs also run a quick power-up sequence each time the charger is connected.
Easily identify which slots are charging, finished or reporting an error without guessing. Quick visual feedback reduces wasted time and uncertainty.
Safe, travel-friendly design - with detection tech and wide input voltage
Latest battery detection recognises wrong polarity and non-rechargeables and triggers a cut-off; full batteries are switched to trickle charge to prevent overheating. An AC flip-down plug and switching power (100–240 V) make the unit suitable for international power systems, though a plug adapter may be required outside the UK.
Charge with confidence at home or while travelling, with safeguards against overcharge and incorrect battery insertion. The compact form factor makes storage and packing straightforward.
