The Ledlenser FLEX3 Power Bank PLUS is a 4-in-1 power management solution for Ledlenser torch owners — a power bank, 18650 battery charger, protective storage case and battery capacity tester in a single IP65-rated polycarbonate housing. The included 18650 battery is the same cell format used in a wide range of Ledlenser torches and head torches, meaning it can be charged in the FLEX3 and then physically swapped directly into a compatible Ledlenser product as a fresh replacement — no waiting for the torch itself to charge.
As a power bank the FLEX3 uses the 18650's 3,400mAh capacity to charge smartphones, earbuds and other USB devices via the output port. As a charger it tops up the 18650 up to 30% faster than charging the battery inside the torch itself. The polycarbonate casing acts as double protection against short circuits, making it compliant for carry-on air travel. Supplied with a 18650 Li-ion battery and USB cable.

Endless Benefits:
- 4-in-1 functionality — power bank for USB device charging, 18650 battery charger, protective storage and battery capacity indicator; four roles in a single IP65-rated unit.
- Swap batteries directly into compatible Ledlenser torches — the included 18650 cell is the same format used in compatible Ledlenser models; charge it in the Flex3, remove it, and slot it straight into your torch for an instant battery change without waiting for a full in-torch recharge cycle.
- Up to 30% faster charging than in-torch — charges the 18650 battery faster than leaving it inside a compatible torch to charge; keep the Flex3 charged and ready for rapid battery turnaround on long trips and extended shifts.
- Battery capacity indicator — check the remaining charge of any 18650 battery before committing it to your torch; useful for those with multiple 18650 cells across different devices.
- IP65 rated — fully dust-tight and water jet resistant; suitable for outdoor, site and all-weather carry.
- Double short-circuit protection — the polycarbonate case adds a second layer of protection beyond the battery's own built-in protection; approved for carry-on air travel.
- Battery and charge indicators — battery level, charge progress and low battery warning visible at a glance during charging.
