Ready-to-shoot power kit

This Kastar BP-70A bundle supplies four lithium-ion batteries and a single charger that powers up to four cells at once. It is built for photographers who use compatible Samsung compact cameras and want spare capacity in the bag. The pack covers models from the ST, PL, ES, SL, MV, TL, DV, AQ and MV series listed in the compatibility data. No other camera brands or battery types are supported.

Thermals and draw at idle

Each cell stores 5.2 Wh at 3.7 V with a 1400 mAh rating. The charger draws 15 W from a 5 V 2-3 A source and delivers 4.2 V at 800 mA for one or two batteries or 500 mA for three or four. Micro-USB and USB-C inputs are provided and a Type-C cable is included. The intelligent display shows charge status and remaining capacity without fan noise or heat concerns in normal indoor use.

Sustained charging behaviour

When all four slots are occupied the charger splits current to 500 mA per cell, extending total cycle time but keeping each battery within safe limits. The lithium-ion chemistry handles repeated top-ups without memory effect. Users who need faster turnaround for two batteries will see 800 mA per slot. The unit does not support simultaneous charging of different battery chemistries or form factors beyond the BP-70A plate.

Questions about this item

How do I install the BP-70A batteries and quad charger, and what step is often missed?

Insert each 3.7 V 1400 mAh BP-70A battery into a charger slot, connect the charger via Micro-USB or Type-C to a 5 V 2–3 A 15 W source, and ensure the correct charging plate is fitted for the BP-70A cells — the plate change is the step most users overlook.

What maintenance or replacement will the BP-70A batteries and charger need over time?

The four 5.2 Wh Li-Ion BP-70A packs will gradually lose capacity after repeated cycles; plan to replace them when run-time drops below usable levels. The quad charger itself has no user-serviceable parts, so it only needs occasional dust removal from the USB ports.

What limit appears first when the quad charger runs all four slots continuously?

With three or four BP-70A batteries inserted, the charger drops each output to 4.2 V 500 mA, so total charge current is capped at 2 A — that shared-current ceiling is the first bottleneck during sustained multi-bay charging.
