Kit contents and target user

This Kastar kit supplies four SLB-10A lithium-ion batteries and one LTD2 dual-slot USB charger. It is built for owners of compatible Samsung, JVC, Zoom or Toshiba cameras who need spare power for long shoots or travel. Photographers using cameras that take a different battery form factor cannot use these cells.

Deciding specification

Each battery delivers 3.7 V and 1400 mAh for a total of 5.18 Wh. The charger accepts 5 V 2-3 A input via Micro-USB or Type-C and outputs 4.2 V at 800 mA per slot, charging two batteries simultaneously. If your camera requires a higher capacity or a different voltage, this pack will not match.

Thermals, noise and power draw

The charger draws up to 15 W from a standard USB power source and runs silently with no moving parts. An LCD panel shows real-time charging status and remaining capacity for each bay. Batteries stay at normal temperature during typical charge cycles.

Questions about this item

What does the 1400 mAh capacity mean for shooting time in a Samsung WB750?

The 3.7 V, 1400 mAh lithium-ion cell stores 5.18 Wh, giving roughly the same runtime as the original Samsung SLB-10A in compatible cameras such as the WB750.

How does the USB charger’s 5 V 2-3 A input limit charging speed?

The charger draws up to 15 W from a USB-A or Type-C port and delivers 4.2 V at 800 mA per slot, so two batteries charge simultaneously at that fixed rate.

Will the 5 × 3 × 3 inch charger fit in a compact camera bag?

The unit measures about 5 by 3 by 3 inches, making it small enough for most camera pouches while still holding two batteries side by side.
