Kastar Ultra Fast Charger Kit and 3-Pack Battery for LP-E17 - Faster

In this review of the Kastar Ultra Fast Charger Kit and 3-Pack Battery for LP-E17 cameras, the bottom line is simple: photographers who need quick turnaround and extra runtime will appreciate the speed and capacity offered here. The kit pairs an intelligent ultra-fast dual-voltage charger with three high-capacity replacement batteries, delivering charge rates advertised as over three times faster than a normal charger and providing the convenience of USB output for powering phones or accessories. For anyone shooting full days, travel, or time-lapse sequences, the combination of faster charging and multiple batteries cuts downtime between shoots.

Key Features

• Ultra-fast charging: The charger outputs 4.2V/8.4V at 1.0A so batteries reach usable charge much sooner than standard chargers, reducing wait time between sessions.
• Worldwide compatibility: With 110-240V input and a 12V car option, the charger works for travel photographers and in-vehicle charging on location.
• High-capacity batteries: The included batteries use quality Japanese cells for longer cycle life and reduced memory effect compared with generic cells.
• Informative LCD: The charger LCD displays charging status, battery capacity, charging voltage, and USB output voltage so users can monitor progress at a glance.
• USB output and wake function: The charger provides a 0.6A USB output to top up phones or accessories and a wake-up function to recover over-discharged cells before charging begins.

Who It's For

This kit is aimed at DSLR and mirrorless shooters who use cameras compatible with the LP-E17 battery, including EOS M3, EOS Rebel T6i/T6s, EOS 750D/760D/8000D and similar bodies; it suits travel shooters, event photographers, and hobbyists who benefit from multiple spare batteries and faster charging cycles. The USB output also makes it handy for creators who carry fewer chargers and want to power small devices from the same unit.

Photographers who require camera-level battery decoding on the camera display should look elsewhere, because these replacement batteries are not decoded and will not show remaining time on compatible Canon bodies. Also, if you rely on a manufacturer's original charger for charging replacement batteries, be aware these cells must be charged with the supplied Kastar charger.

Pros & Cons

Cons

• Batteries are not decoded and will not display remaining time in-camera, which may be inconvenient for some users.
