Kastar EN-EL14a 4-Pack Battery & LTD2 USB Charger - Dual Charge, Fast

In this review the Kastar 4-Pack EN-EL14a Battery & LTD2 USB Charger is assessed for photographers who need reliable spare power for Nikon cameras. The reviewer finds it most useful for travel shooters and hobbyists because it bundles four 1700mAh lithium-ion batteries with a compact dual USB charger that can charge two batteries simultaneously and shows charge status with intelligent LEDs. The kit is notable for offering multiple input options and a small 5V USB power draw, which makes keeping cameras powered away from a mains outlet straightforward and predictable.

Key Features

• Battery Capacity: Each 1700mAh lithium-ion cell provides extended shooting time compared with typical single-pack spares, reducing interruptions on location shoots.
• Dual Charging: The LTD2 charger can charge two batteries at once, so shooters can rotate batteries faster between sessions and minimize downtime.
• USB Power Input: With 5V input and support for both Micro-USB and Type-C, the charger works from power banks, car chargers, or laptop ports for versatile field charging.
• LED Status Display: Intelligent LED indicators show charging status and give a quick visual read on remaining battery condition during charging cycles.
• Interchangeable Plate: The charger plate can be changed to accept different battery shapes, adding flexibility for users who own multiple battery types.
• Compact Design: Lightweight and easy to carry, the kit fits into camera bags without adding significant bulk for travel photography.

Who It's For

This kit is aimed at hobbyist and enthusiast photographers who shoot with Nikon models that accept EN-EL14/14a/14b batteries, including D3x00 and D5x00 series and many Coolpix models. It is ideal for weekend shooters, travel photographers, and anyone who prefers carrying multiple spares rather than relying on a single OEM battery.

It is less appropriate for professional users who demand manufacturer-branded batteries for warranty or prolonged heavy-duty use, or for photographers who need ultra-rapid professional charging times; this kit favors convenience and portability over the fastest possible recharge.

Pros & Cons
