Kastar 4-Pack EN-EL14 Battery and LTD2 USB Charger - Extra Power

In this review the focus is on photographers who need reliable spare power for Nikon cameras that use the EN-EL14 family. The Kastar 4-Pack EN-EL14 Battery and LTD2 USB Charger bundle is aimed at hobbyists and prosumers who shoot events, travel, or long sessions and want the convenience of charging multiple batteries from USB power. The single biggest reason to buy is the combination of four 1700mAh lithium-ion batteries and a dual USB charger that can handle two batteries at once, which minimizes downtime during shoots.

Key Features

• Battery Type and Capacity: 1700mAh lithium-ion batteries provide extended shooting time compared with a single stock cell and are suitable for long sessions away from mains power.
• Dual Battery Charging: The LTD2 USB charger can charge two batteries simultaneously, reducing wait time when multiple batteries need topping up between shoots.
• Flexible Input Options: The charger accepts both Micro-USB and Type-C inputs and includes a Micro-USB cable, so it can be powered from a power bank, laptop, or USB wall adapter.
• Interchangeable Plate: The charger can change the plate to charge different battery shapes, adding compatibility and practical flexibility for mixed battery kits.
• Intelligent LED Display: An LED indicator shows charging status and relative battery capacity, helping to plan which battery to use next.
• Compact, Travel-Friendly Design: With USB 5V input and a compact footprint, the charger is easy to carry in a camera bag for location work.

Who It's For

This pack is best for Nikon DSLR owners using EN-EL14, EN-EL14a or EN-EL14b batteries who need extra runtime without depending on proprietary mains chargers. Wedding photographers, travel shooters, and anyone who shoots for extended periods will appreciate having four spare cells and a charger that runs from common USB supplies.

It is less suited to users who require OEM-branded batteries for manufacturer warranty reasons or those who need extremely fast high-current charging from a dedicated AC charger; the LTD2 USB charger is designed for portability and convenience rather than rapid bulk charging from mains only.

Pros & Cons

Pros

• Includes four 1700mAh lithium-ion batteries, giving ample reserve power for long shoots.
• The dual USB charger can top up two batteries at once, which speeds turnaround between uses.
• Flexible Micro-USB and Type-C input and a supplied Micro-USB cable make in-field charging simple from power banks.

Cons

• Charging speed is limited by USB input and the charger output (8.4V 800mA per slot), so it is not as fast as some high-power AC chargers.
• This is a third-party replacement rather than a Nikon-branded pack, which some users may prefer to avoid for warranty concerns.
