Upgraded Battery Fast Charger Case for Nikon EN-EL15B Batteries - Dual

In this review the focus is on a compact, multi-function charger case for Nikon EN-EL15B batteries intended for photographers who travel or shoot extensively. The bottom line: this kit combines two genuine-feeling EN-EL15B batteries with a dual-channel charger case that displays charge status on a large LCD and stores a spare SD card, making it a practical replacement or backup for users of Nikon D7500, Z6, Z7, D850 and similar models. The reviewer found the charger reliable at restoring a dead battery and appreciated the padded magnetic cover and lanyard for on-the-go convenience.

Key Features

• Dual-channel charging: The charger supports charging two EN-EL15B batteries at the same time so you can keep two spares topped up between shoots.
• Large LCD display: A clear screen shows remaining power and charging status so you can see progress without guesswork.
• Integrated storage: An extra SD card slot built into the case provides secure storage for a spare card during travel.
• Protective magnetic cover: A strong magnetic lid keeps batteries protected inside the compact case to reduce risk of contact damage in a bag.
• Carry convenience: The included lanyard lets you hang the charger case from a bag for easy access when moving between locations.
• Safety protections: Circuit safeguards prevent over-charge, over-current, over-voltage, over-temperature and short-circuit for safer charging.

Who It's For

The kit is a good fit for enthusiast and pro photographers who use Nikon cameras compatible with EN-EL15B batteries, including D7500, D500, D850, Z6 and Z7 series cameras, and who want a compact way to store and charge two batteries together. It benefits travel shooters who value a small footprint, visual charge feedback via the LCD, and a place to carry an extra SD card.

Those who need a portable power bank to charge devices in the field should look elsewhere, as this unit is not designed to act as a portable USB power source. Also, owners of Nikon Z F or Z6III should verify compatibility since the product is not listed for those models.

Pros & Cons

Pros

• Includes two EN-EL15B batteries that users report match original performance for typical shooting needs.
• Dual-channel design with an LCD gives clear feedback and faster turnaround by charging two batteries simultaneously.

Cons

• Cannot be used as a portable charger, so it does not replace a power bank for charging phones or cameras via USB.
• Compatibility note excludes some newer models like Nikon Z6III and Z F, so check camera support before purchase.
