Kastar 4-Pack EN-EL3e Battery and LTD2 USB Charger - Reliable Backup

In this review the Kastar 4-Pack EN-EL3e Battery and LTD2 USB Charger is evaluated for photographers who need dependable spare power for older Nikon bodies and grips. The bottom line: this kit is for users who want multiple full-capacity replacements and a compact dual charger that can top up two batteries at once from a USB source. The reviewer found the combination of 2650mAh lithium-ion cells and a flexible USB charger makes it a practical, portable solution for shoots where mains charging is inconvenient.

Key Features

• High capacity battery: Each 2650mAh lithium-ion cell provides extended shooting time compared with many original batteries, reducing interruptions for mid-day swaps.
• Dual charging: The LTD2 USB charger can charge two batteries simultaneously, so a pair of spares becomes ready much faster than single-slot options.
• Universal USB input: With Micro-USB and Type-C inputs and a supplied Micro USB cable, the charger works from power banks, laptops, or wall adapters for on-location flexibility.
• Adjustable plate: The charger allows the plate to be changed to fit different battery shapes, making it compatible with EN-EL3e family cells and similar chargers like MH-18 series.
• Intelligent LED display: Simple LED indicators show charging status and relative battery capacity so it is straightforward to monitor progress without guessing.

Who It's For

The kit is aimed at photographers who own Nikon models that use EN-EL3e family batteries - including D80, D90, D200 and related bodies - and who need multiple spares for extended shoots, travel, or fieldwork. It is particularly useful for portrait, wedding, or event photographers who run multiple batteries between sessions and want a compact charger that runs from USB power.

Photographers who require manufacturer-branded batteries for warranty or service reasons, or those using the very newest camera platforms that need higher-voltage cells, should look elsewhere. This kit is optimized for older Nikon DSLRs and compatible grips rather than modern mirrorless systems.

Pros & Cons

Pros

• Four 2650mAh lithium-ion batteries provide plentiful backup capacity for long shoots.
• Charger charges two batteries at once, saving time between sessions.
• USB input options and included Micro USB cable make it easy to charge from power banks or laptops.
• Interchangeable plate and LED indicators add convenience and clarity during charging.

Cons

• Designed for EN-EL3e family batteries and older Nikon models, so it is not suitable for cameras requiring different battery formats.
• The charger output is limited to the specified 800mA channels, so charging is not as fast as some high-power dedicated AC chargers.
