Kastar 3-Pack Battery and USB Charger Replacement - Dual Charge Kit

In this review the Kastar 3-Pack Battery and LTD2 USB Charger is evaluated for camcorder owners who need reliable spare power and flexible charging. The bottom line: this kit is best for users of compatible JVC Everio camcorders who want a compact, portable solution that charges two batteries at once and reports status with LEDs. It replaces common JVC battery models and includes both Lithium-Ion 1650mAh cells and a USB dual charger that accepts Micro-USB and Type-C input, making it convenient for trips or extended shoots.

Key Features

• Battery Type: The included Lithium-Ion 1650mAh batteries provide a direct replacement for original JVC packs so you can resume shooting without compatibility worries.
• Dual Charging: The LTD2 charger can charge two batteries simultaneously, cutting downtime when multiple spares are in circulation.
• Interchangeable Plate: The charger allows changing the plate to accommodate different compatible battery plates, increasing flexibility across models.
• USB Power: With Micro-USB and Type-C input and a supplied Micro-USB cable, the charger runs from common 5V 2-3A power sources for travel-friendly charging.
• Smart LED Display: The intelligent LED indicators show charging status and relative battery capacity so you can see progress at a glance.
• Portable Output: The charger outputs 4.2V at 800mA per bay, which is appropriate for safe, steady charging of these replacement batteries.

Who It's For

The kit is targeted at owners of JVC Everio camcorders listed as compatible, or anyone who needs multiple spare batteries and a compact charger for field use. Photographers and videographers who shoot for extended periods will appreciate having two batteries charged at once and the ability to use USB power banks.

It is less appropriate for users who require OEM-branded batteries for warranty reasons or those who need extremely fast charging beyond the specified 800mA per bay. If you need very high-capacity or manufacturer-specific cells, consider official replacements.

Pros & Cons

• LED indicators provide clear charging status so users know when batteries are ready.

Cons

• Charging current is limited to 800mA per bay, so recharge times are moderate rather than rapid.
