Kastar 4-Pack LP-E6 Battery and LTD2 USB Charger - Reliable Power

In this review the Kastar 4-Pack LP-E6 battery kit with LTD2 USB charger is assessed for photographers who need dependable spare power on shoots. The bottom line: this kit is for Canon users who want multiple high-capacity replacements and a flexible USB charger that can top up two batteries at once. The reviewer found the set especially useful for long sessions and travel because the 2950mAh lithium-ion cells and dual USB inputs reduce downtime without requiring camera-specific mains chargers.

Key Features

• High capacity cells: Each battery is rated at 2950mAh, which gives longer run time between swaps compared with lower capacity replacements.
• Dual-bay USB charger: The LTD2 charger can charge two batteries simultaneously so photographers can keep spares ready without waiting for sequential charging.
• Multiple input options: The charger accepts both Micro-USB and Type-C input and includes a Micro USB cable, making it convenient to power from power banks or USB adapters.
• Smart LED indicators: The intelligent LED display shows charge status and battery capacity so users can see progress at a glance and avoid guessing which cell is topped up.
• Portable power design: With a 5V 2-3A 15W input and compact form factor, the charger is easy to carry for location shoots and fits in camera bags.

Who It's For

This kit is aimed at Canon DSLR and mirrorless shooters who use LP-E6 series batteries, especially those who shoot long weddings, events, or extended wildlife sessions where swapping batteries quickly matters. Owners of models such as the EOS 6D series, 5D series, 7D series, 70D/80D, and compatible cinema cameras will find the batteries match native LP-E6 specifications and the extra capacity useful.

Casual users who rarely change batteries or those who want OEM chargers integrated with camera bodies may prefer original-brand batteries and chargers. Also, users who require bundled AC adapters or regional plugs should verify their charging setup, since this kit is centered on USB charging.
