Kastar 4-Pack Battery and USB Dual Charger for Canon EOS Cameras

In this review the Kastar 4-Pack Battery and LTD2 USB Charger is assessed for photographers who need dependable spare power on shoots and trips. The pack pairs four 1450mAh lithium-ion batteries with an intelligent dual USB charger that can top up two batteries at once, and includes both Micro-USB and Type-C charging options. The single biggest reason to buy is straightforward: this kit extends shooting time with compact, swappable batteries plus a portable charger that works from common 5V USB power sources.

Key Features

• Battery Type: Lithium-ion cells provide a compact, lightweight replacement that fits Canon LP-E17 camera models for extended shooting sessions.
• Capacity and Voltage: 1450mAh at 7.2V gives a practical balance of runtime and size for mirrorless and DSLR bodies that accept LP-E17 type batteries.
• Dual Charging: The charger can charge two batteries simultaneously or one at a time by changing the plate, which speeds turnaround when multiple batteries are in rotation.
• USB Powered: With Micro-USB and Type-C input and a 5V 2-3A 15W input spec, the charger can be powered from power banks or USB wall adapters for field use.
• Intelligent LED Display: The LED indicators show charging status and relative battery capacity so the user can gauge readiness without guesswork.
• Portable Design: The compact charger and four spare batteries are easy to pack in a camera bag for travel or a long day of shooting.

Who It's For

This kit is aimed at hobbyist and enthusiast photographers who use Canon cameras that accept LP-E17 batteries and who need multiple spare batteries for day-long shoots, travel, or backup power. It is especially useful for users of Canon mirrorless and entry to mid-level DSLR models where original batteries are relatively small and drains are common during video or burst shooting.

Photographers who require manufacturer-branded charging with fully decoded battery communications may want to look elsewhere, since this is a third-party replacement pack and the product notes state it is not compatible with certain original Canon chargers. Studio professionals who demand OEM accessories for warranty or camera-menu compatibility should consider original batteries instead.
