Kastar LP-EL 4-pack with dual USB charger

The set supplies four 7.2V 2600mAh lithium-ion batteries and a single charger that powers two cells at once. It is built for photographers using Canon Speedlite EL-5 or EL-1 flashes who need reliable spare power during long shoots.

Replaces single OEM batteries

Swapping to this kit makes sense when you regularly deplete one pack and want continuous flash operation without waiting for a single bay to finish. The 15W input and 8.4V 800mA dual output cut total recharge time compared with the stock one-at-a-time charger.

Verify your flash accepts the LP-EL form factor

Confirm the Speedlite model is listed as compatible before ordering. The charger requires a 5V 2-3A USB source via Micro-USB or Type-C; ensure you have a suitable adapter or power bank. The package includes a Micro-USB cable only.
