Three-battery kit with LCD triple charger

This set supplies three lithium-ion batteries rated at 3.6 volts and 1200 milliampere-hours each, plus a charger that powers all three simultaneously from a single USB source. It targets owners of compatible Sony Cyber-shot and Bloggie cameras who want spare cells and a compact way to replenish them without a wall wart.

4.32 watt-hour cells and triple charging headroom

Each cell stores 4.32 watt-hours, giving a day of typical shooting per battery; the charger delivers 0.5 amps per slot so three flat packs reach full capacity in parallel. The arrangement suits travel kits where outlets are scarce, but it cannot fast-charge a single cell beyond the fixed 0.5-amp rate.

USB 5-volt input and Micro USB tether

The charger draws 5 volts at up to 2 amps from any standard USB port, computer or car adapter, and ships with a Micro USB cable for that link. It lacks USB-C or Power Delivery negotiation, so it will not pull higher voltages from newer bricks, and the fixed Micro USB connector cannot be replaced with a shorter or angled lead.
