Kastar 2-Pack BP-828 Replacement Batteries and LTD2 USB Charger - Dual

In this review the focus is a straightforward replacement power solution for Canon users who need extra runtime without carrying multiple single chargers. The Kastar 2-Pack BP-828 kit includes two 7.4V 3300mAh lithium-ion batteries and an LTD2 USB dual charger that can top two cells at once, and our review found it best for videographers and camera owners who value battery capacity and flexible USB charging. The single biggest reason to buy is the convenience of charging two compatible BP-828 style batteries simultaneously from a USB power source while retaining an intelligent LED status display.

Key Features

• High capacity batteries: Each 3300mAh lithium-ion battery gives extended run time for longer shoots and reduces interruption for recharging.
• Dual battery charger: The LTD2 USB charger accepts Micro-USB and Type-C input and can charge two batteries at the same time for faster turnaround between sessions.
• Flexible input options: With a 5V 2-3A 15W input specification the charger can be powered from a power bank or USB wall adapter for on-the-go charging.
• LED status indicators: Intelligent LED display shows charging status and relative battery capacity so users can know when a pack is ready.
• Interchangeable plate: The charger can change the plate to fit different battery shapes, adding compatibility and usability for similar Canon battery models.

Who It's For

The Kastar 2-Pack is ideal for solo shooters, small production crews, and event videographers using Canon XF and VIXIA models who need more runtime and the ability to charge two packs simultaneously. It is especially useful for field work where access to mains power is limited and a USB power bank or vehicle USB outlet is the primary charging method.

Users who require manufacturer-authorized batteries for warranty reasons or those who need in-camera charging features built into a proprietary charger may want to consider original equipment alternatives. Also, those who never use USB charging or only need one spare battery may find a single battery solution more compact.

Pros & Cons
