Kastar 2-Pack DMW-BLB13 Battery and LTD2 USB Charger - Dual Charge Kit

In this review of the Kastar 2-Pack DMW-BLB13 Battery and LTD2 USB Charger, the bottom line is simple: this kit is aimed at photographers who need reliable spare power and a flexible way to charge two batteries on the go. The reviewer found the two 1650mAh lithium-ion batteries and the dual USB charger a practical match for older Panasonic Lumix mirrorless bodies, with straightforward USB power input options and an intelligent LED that makes monitoring charging status painless. It is best for users seeking cost-effective extra runtime without changing camera habits.

Key Features

• Battery Type: The included lithium-ion 1650mAh cells offer comparable runtime to OEM batteries for extended shooting sessions.
• Dual Charging: The LTD2 charger can charge two batteries simultaneously, which reduces downtime between shoots.
• Adjustable Plate: The charger allows changing the charging plate to accept different battery variants, increasing compatibility with several DMW-BLB13 family models.
• USB Power Input: With both Micro-USB and Type-C input options and a supplied Micro USB cable, the charger works from power banks, wall adapters, or laptops for flexible field charging.
• Smart LED Display: Intelligent LED indicators show charging status and relative battery capacity so users can confirm charge progress at a glance.
• Compact Design: The charger and spare batteries are easy to carry in a camera bag, making them convenient for travel and day trips.

Who It's For

This kit is ideal for owners of Panasonic Lumix models that use the DMW-BLB13 family batteries, such as the GF1 series and several G and GH models, who want a low-cost way to keep multiple batteries ready. It fits well for hobbyists, event shooters on a budget, and travelers who pair a power bank with the charger for remote charging.

Photographers who demand factory branded batteries for warranty reasons or those who need very fast high-current charging should look elsewhere; the charger outputs up to 800mA per slot and is designed for convenience and compatibility rather than rapid professional-level charging.

Pros & Cons

Pros

• Two batteries included provide immediate spares and extend shooting time without waiting to recharge a single cell.
• Charger supports simultaneous charging of two batteries and can switch plates for related battery variants, improving versatility.
• Micro-USB and Type-C inputs plus an included cable make it simple to power the charger from common USB sources.
• LED indicators provide clear, useful information on charging status and capacity.

Cons

• Charging speed is modest at 800mA per slot, so full recharge times are longer than some dedicated high-current chargers.
• Not a direct replacement for chargers requiring specialized high-power adapters used by some professional setups.

It is not aimed at those who require the fastest possible recharge, but for most hobbyists and travelers the dual-charge capability, compatibility with several DMW-BLB13 variants, and clear LED indicators make this kit a sensible purchase.
