FirstPower EN-EL25 Camera Battery 2-Pack - USB-C Fast Charging

In this review the FirstPower EN-EL25 2-pack is evaluated as a practical replacement battery set for Nikon ZFC, Z30 and Z50 shooters who want longer outings without carrying a bulky charger. The single biggest reason to consider these cells is the built-in USB-C portable fast charging that lets you top up both batteries from a USB power source in roughly 2.5 hours using the included 2-in-1 cable, removing the need to carry the original MH-32 charger for short trips.

Key Features

• USB-C charging: A Type-C port on the batteries allows direct charging from power banks or wall adapters so you can recharge without a separate dock.
• Fast dual charge: High-current 5V/1.5A input charges two batteries simultaneously in about 2.5 hours, useful between shoots.
• Sufficient capacity: Each 1600mAh (7.6V, 12.16Wh) cell gives a reliable power reserve to extend shooting time when carrying a pair.
• Full camera compatibility: The batteries are fully decoded to work with Nikon Z30, Z50 and ZFC cameras without compatibility warnings.
• Safety protections: Built-in intelligent chip provides over-voltage, over-current, short circuit, high temperature and over-charge protection for safe use.
• Charging indicator: An LED shows red while charging and green when full, making it easy to confirm status at a glance.

Who It's For

The FirstPower EN-EL25 2-pack is aimed at casual and enthusiast photographers who use Nikon ZFC, Z30 or Z50 cameras and want a compact, travel-friendly way to extend shooting time without carrying an additional charger. Its portable fast charging and compatibility with USB power banks make it well suited for day trips, vlogging, or run-and-gun work where wall power is limited.

Photographers who rely on heavy, continuous professional shooting or need manufacturer support contracts may prefer original Nikon batteries and chargers. Also, those who want the longest possible single-charge runtime should note these are replacement cells of 1600mAh capacity rather than higher-capacity aftermarket options.

Pros & Cons

Pros

• Direct USB-C charging removes the need for a separate charger and simplifies travel.
• Comes as a two-pack so users can swap batteries and significantly extend shoot time.
• Fully decoded compatibility prevents camera warnings and ensures normal operation.
• Built-in safety protections and CE/FCC/RoHS compliance increase peace of mind.

Cons

• Capacity is the same as standard EN-EL25 at 1600mAh, so it does not extend per-battery runtime beyond OEM levels.
• Serious pros who want the longest runtime per charge may prefer higher-capacity third-party cells or multiple spares.
