1700mAh 4-Pack Battery with LTD2 USB Dual Charger - Portable Power

Our review of this Kastar kit finds it aimed at travelers and casual photographers who need reliable spare power without bulk. The 1700mAh batteries are a direct replacement for Panasonic DMW-BCG10 series cells, and the included LTD2 USB dual charger handles two batteries at once or one at a time with a swappable plate. For anyone using the Lumix DMC-ZS19/ZS20/ZS25 cameras, this set delivers sensible capacity, multiple input options and a compact charger that stays useful on trips.

Key Features

• 1700mAh lithium-ion cells: provide a balanced mix of capacity and weight for extended shooting sessions without dramatic added bulk.
• Dual battery charging: the LTD2 charger can charge two batteries simultaneously to reduce downtime between shoots.
• Swappable charging plate: lets the charger accept different battery contacts so the same unit adapts to multiple battery styles.
• Multiple input options: Micro-USB and Type-C inputs allow charging from common power banks, wall adapters or laptop ports.
• Smart LED indicators: the charger shows charging status and relative battery capacity so you can see progress at a glance.
• Compact 5V input: the charger accepts 5V 2-3A input and runs on typical USB power sources for travel convenience.

Who It's For

This kit suits photographers who own Panasonic Lumix cameras that use DMW-BCG10 type batteries and who want multiple spares for day trips or vacations. The 1700mAh capacity is practical for casual to enthusiast use where extra runtime is needed but ultra-high capacity is not essential.

Power users who shoot all day on professional assignments and need the very highest capacity or fastest recharge times should look at specialty high-capacity batteries or faster dedicated chargers. Also, buyers who require a charger without any cables should note this kit includes a Micro USB cable, not a separate Type-C cable.

Pros & Cons

Pros

• Includes four replacement 1700mAh batteries to keep a camera running across long outings without searching for power.
• Dual charging capability reduces wait time by charging two batteries at once.
• Multiple inputs and a Micro-USB cable make the charger flexible for travel use with common power sources.

Cons

• Charger supplies modest 800mA per slot, so refill times are not as fast as higher-current dedicated chargers.
• The kit includes only a Micro-USB cable; users who prefer Type-C will need to supply their own cable for that input.
