Four-battery kit for Panasonic Lumix TZ/ZS cameras

This Kastar set includes four lithium-ion DMW-BCM13 batteries and a single charger that powers all four at once. It is aimed at photographers who need extended shooting time for travel or events without swapping cells mid-session. The bundle suits owners of compatible Lumix TZ60, TZ61, TZ70, ZS27 and ZS30 models.

1800 mAh capacity per cell

Each battery delivers 3.7 V and 1800 mAh for a total energy of 6.66 Wh. That single figure determines whether the pack matches the runtime you expect from the original Panasonic cell. If your workflow demands a different capacity, this kit will not meet it.

Quad USB charger with dual-input ports

The charger accepts power through Micro-USB or USB-C and ships with a USB-C cable. It can charge one or two batteries at 800 mA each, or three to four at 500 mA each, while an on-board display shows status and remaining capacity. The unit also supports interchangeable plates for other battery types.

Questions about this item

How long will the 1800mAh capacity last in a Panasonic Lumix DMC-TZ70?

The 1800mAh rating delivers 6.66 Wh of energy; actual shooting time varies with screen brightness, zoom use and video recording but typically covers several hundred stills per charge.

What does the 5V 2-3A USB input limit when charging four batteries?

With all four slots occupied the charger splits its 15 W input to 500 mA per battery, so a full cycle takes longer than charging one or two cells at 800 mA.

Will the 3.5 by 2 by 2.5 inch charger block adjacent outlets on a power strip?

The compact footprint fits most strips without covering neighbouring sockets, and the supplied Type-C cable reaches the strip easily.
