Kastar 4-Pack BP-828 Battery and LTD2 USB Charger - Dual Charge Kit

In this review the reviewer looks at the Kastar 4-Pack BP-828 replacement batteries and the LTD2 USB dual charger as a practical power kit for Canon camera owners. The bottom line: this bundle is aimed at videographers and content creators who need a reliable set of spare power and a compact, flexible charging solution; the single biggest reason to buy is the combination of high capacity 3300mAh lithium-ion cells and a USB-powered dual charger that can top up two batteries at once, making it easy to keep multiple cameras or spares ready when shooting on location with limited mains access.

Key Features

• High capacity: Each replacement cell is a 3300mAh, 7.4V lithium-ion battery that provides extended runtime compared with many stock cells for longer recording sessions.
• Dual charging: The LTD2 USB charger can charge two batteries simultaneously, reducing downtime when you have multiple spares to cycle.
• Flexible input: The charger accepts Micro-USB and Type-C input and ships with a Micro-USB cable, so it can be powered from power banks or USB chargers in the field.
• Interchangeable plate: The charger lets you change the plate to fit compatible Canon BP-820 and BP-828 battery models, increasing compatibility with several camera models.
• Intelligent LED display: The charger uses LED indicators to show charging status and relative battery capacity so users can monitor progress without guessing.

Who It's For

This kit is best for Canon camera owners who use models that accept BP-828 or BP-820 batteries and who need multiple spares for long shoots, event coverage, or travel. The combination of 3300mAh batteries and a USB-powered dual charger is particularly useful for run-and-gun shooters who rely on power banks or in-car USB charging instead of wall outlets.

Photographers or casual users who only shoot short clips or rarely swap batteries may find this 4-pack overkill; similarly, those who require official manufacturer warranties or branded chargers may prefer to source original batteries and chargers instead.
