Kastar 4 Pack Battery and LCD Triple USB Charger - Fast Triple

In this review of the Kastar 4 Pack Battery and LCD Triple USB Charger, the bottom line is clear: this bundle is for GoPro owners who want extra runtime and a compact way to recharge multiple batteries at once. The pack pairs four 1680mAh lithium-ion replacement batteries with a small LCD USB triple charger that can top up three cells simultaneously, making it a practical kit for day trips, multi-day shoots, or time away from mains power. The reviewer found the LCD readout and USB power options to be the single biggest convenience when juggling several camera batteries.

Key Features

• Battery Capacity: Each 1680mAh lithium-ion cell provides extended run time compared with smaller third-party cells, giving more usable recording time between swaps.
• Voltage Compatibility: The 3.85V nominal battery voltage matches the original GoPro replacements, helping maintain camera compatibility and reliable operation.
• Triple USB Charger: The Kastar LCD USB triple charger charges three batteries at once from a single USB source, reducing wait time when multiple spares are in use.
• LCD Status Display: The intelligent LCD shows charging status and battery capacity so you can see charge progress at a glance without guessing.
• USB Powered: The charger accepts 5V 2A input and runs from wall, car, or computer USB ports and ships with a Micro USB cable for flexibility in the field.
• Portable Design: The charger and four compact batteries are easy to carry in a camera bag or pocket, keeping weight and bulk low for travel.

Who It's For

The Kastar 4 Pack and triple charger is aimed at action camera users who regularly shoot long sessions or travel and need multiple spare batteries that can be recharged quickly. It is a sensible option for weekend adventurers, vloggers, and casual filmmakers who want a straightforward way to keep three batteries topped up from a USB power source.

This is not targeted at professional studios that require high-speed dedicated charging docks with proprietary smart charging networks, nor for users who need official OEM warranty coverage. If you need integrated camera-to-charger diagnostics or branded factory batteries, consider official replacements instead.
