Three-Battery Kit with Four-Bay USB Charger

This kit supplies three lithium-ion batteries rated at 11.8 Wh and 1650 mAh each, plus a compact charger that can fill four packs simultaneously. It targets photographers using compatible Sony mirrorless bodies, Cyber-shot RX10 series cameras or NEX models who need reliable spares for long shooting days. The charger accepts both Micro-USB and USB-C input, so it works with common power banks or wall adapters.

Thermals Noise and Power Draw

Each cell operates at 7.2 V and the charger delivers 8.4 V at up to 800 mA per bay when one or two batteries are inserted, dropping to 500 mA per bay with three or four cells. The unit draws a maximum of 15 W from a 5 V 2-3 A source and runs silently with no moving parts. An integrated LCD shows real-time capacity and charging status for every slot.

Sustained Load Behaviour

Under continuous multi-bay charging the current per bay reduces to 500 mA, extending the total cycle time but keeping temperatures low across all four positions. The intelligent controller balances the load so no single cell overheats during extended sessions. Photographers who need faster single-bay top-ups can charge one or two packs at the higher 800 mA rate instead.

Questions about this item

How do I power the Kastar NP-FW50 quad charger and what is the step users often miss?

Connect the charger via Micro-USB or USB Type-C to a 5V 2-3A 15W source; the included Type-C cable works, but users often forget to use a 15W adapter so all four slots can run at full speed.

When will the three 1650mAh 7.2V Li-Ion batteries in this kit need replacement?

Expect 300–500 full charge cycles before capacity drops to roughly 80% of the original 11.8Wh; after that point runtime shortens noticeably and the batteries should be swapped out.

What charging-current limit appears first when all four NP-FW50 batteries are docked simultaneously?

With four batteries inserted the charger drops each slot to 500mA at 8.4V, so the per-battery rate is the first bottleneck during sustained multi-bay charging.
