Four NP-BX1 batteries and triple USB charger

This set includes four lithium-ion batteries rated at 3.7V and 1240mAh each, plus a charger that powers three cells simultaneously. It targets photographers and videographers who use compatible Sony Cyber-shot, RX, HX, WX, FDR or HDR-AS cameras and need spare power for long shoots.

LCD charger with triple simultaneous slots

The charger shows real-time status and capacity on an LCD panel while delivering 4.2V at 0.5A to each of its three bays. A micro-USB cable is supplied so the unit can draw 5V 2A from a wall adapter, car charger or computer USB port.

Simple USB installation, watch cable power

Plug the micro-USB cable into any 5V 2A source, insert up to three batteries and the LCD confirms charging progress. The only common issue is using a weak USB port or cable that cannot supply the required 10W input, which stalls the charge cycle.

Questions about this item

How long do the 1240mAh Li-Ion batteries last before they need replacing?

Lithium-ion cells typically deliver several hundred charge cycles; with four batteries in rotation you can spread wear and extend the time before any single pack drops below useful capacity.

What limits continuous charging when all three bays are active?

The charger outputs 4.2V at 0.5A per bay from a 5V 2A 10W USB input, so the 10W supply is the bottleneck when three batteries charge together.

How much heat or noise does the LCD triple charger produce during all-day use?

The unit has no fan; it relies on passive cooling from the 10W input, so it runs silently and stays only warm to the touch even during extended sessions.
