Kastar 3300mAh Battery and Dual USB Charger for Canon BP-820 - Single

In this review the Kastar 1-Pack battery and LTD2 USB dual charger is judged as a practical, no-frills power solution for Canon camcorder owners who need reliable spares. The bottom line: this combo is best for videographers who want a high-capacity replacement battery and a portable charger that can handle two batteries on the go. It stands out because the battery is a higher-capacity 3300mAh Lithium-Ion cell and the charger accepts both Micro-USB and Type-C inputs, making it easy to top up from common power banks and phone chargers.

Key Features

• High capacity battery: The 3300mAh Lithium-Ion battery provides extended recording time compared with many standard replacements, reducing the frequency of swaps during shoots.
• Dual charging capability: The charger can charge two batteries simultaneously, which is useful when you need a ready spare without waiting between charges.
• Changeable charging plate: The unit accepts a swap of the plate to fit different battery shapes, offering flexibility for compatible BP series cells.
• Multiple input options: With Micro-USB and Type-C inputs and a supplied Micro USB cable, the charger can be powered from common adapters and power banks while traveling.
• Intelligent LED display: The USB dual charger shows charging status and battery capacity via LEDs, helping avoid guesswork about remaining charge.
• Portable power draw: The charger runs on 5V 2-3A input and outputs 8.4V at 800mA per bay, balancing charge speed and battery longevity.

Who It's For

The Kastar 1-Pack is aimed at Canon XA and VIXIA owners who need a dependable replacement battery that matches BP-820 and BP-828 form factors and want a compact charger for field use. It suits event videographers, independent filmmakers, and hobbyists who value extra runtime and the convenience of USB-powered charging.

It is less suitable for users who require manufacturer-branded chargers for warranty reasons or those who need extremely fast rapid-charging beyond the specified 800mA per bay. Also, buyers requiring an AC-only desktop charger without USB inputs should consider other dedicated charging units.

Pros & Cons

Pros

• High 3300mAh capacity delivers longer runtime between swaps for extended shoots.
• Dual-bay USB charging lets users top up two batteries at once from portable power sources.
• Included Micro USB cable and support for Type-C input offer flexible charging options in the field.

Cons

• Charge current is moderate at 800mA per bay, so charging two batteries simultaneously takes several hours.

The Kastar 3300mAh battery and LTD2 USB dual charger is a sensible, value-oriented replacement for Canon BP-820/BP-828 users who need extra runtime and USB charging flexibility.
