Kastar 4 Pack Battery Compatible with Canon LP-E6 / LP-E6N - USB

In this review the Kastar 4 Pack Battery is assessed for photographers and videographers who rely on Canon LP-E6 style power. The bottom line: these batteries stand out because they add convenient Micro USB charging alongside standard compatibility with Canon LC-E6 chargers, which makes them useful on shoots without access to a dedicated charger. The review focuses on real-world runtime, charging convenience and camera compatibility to help readers decide if this high-capacity, portable solution fits their kit.

Key Features

• USB Charging: Micro USB input lets users top up batteries from a 5V 2A adapter or power bank when a camera charger is unavailable, making on-the-go charging simple.
• High Capacity: Each battery is rated at 2300mAh which aims to provide longer runtime than many stock LP-E6 cells for all-day shooting in compatible cameras.
• Wide Camera Compatibility: Works with a long list of Canon DSLR and cinema models as well as third-party monitors and cameras, reducing the need for multiple battery types in a mixed kit.
• LED Charge Indicator: Built-in LED shows red while charging and green when full, giving a clear visual cue so users know when a cell is ready.
• Charger Compatibility: Can be charged in standard Canon LC-E6 and LC-E6E chargers as well as via USB, offering flexibility depending on the shoot environment.

Who It's For

This 4 pack is a practical choice for freelance photographers, indie filmmakers and content creators who use Canon LP-E6 compatible cameras such as EOS 5D series, 6D, 7D family and newer models like the 80D and 90D, or users of Blackmagic Pocket Cinema cameras and Z CAM E2C that accept LP-E6 form factor. The extra capacity and USB charging make it appealing for long days on location or travel when carrying fewer accessories matters.

It is less suitable for users who require guaranteed factory OEM warranty expectations or those who expect identical long-term lifespan to original manufacturer cells; a few users have reported mixed capacity and lifespan over time, so professionals with critical uptime requirements may prefer OEM batteries or carry backups and replacement planning.

Pros & Cons

Pros

• USB charging adds real convenience for fast top-ups from wall adapters or power banks.
• Higher stated capacity at 2300mAh aims to extend shooting time between swaps.
• Broad compatibility with Canon cameras, grips and several cinema monitors reduces accessory clutter.
• LED indicator provides an easy-to-read charge state without a charger.

Cons

• Customer reports show mixed real-world capacity and some long-term degradation after about a year, so longevity may vary.
• One report of partial charging to 60% suggests occasional inconsistency in individual cells.
