FirstPower EN-EL14/EN-EL14a Battery 3-Pack with Triple Charger

In this review the focus is on photographers who need reliable backup power for long shoots or travel. The FirstPower 3-pack delivers three 1500mAh EN-EL14/EN-EL14a batteries and a triple-slot charger, and the single biggest reason to consider it is straightforward: it replaces multiple single batteries and charges them simultaneously from USB-C or Micro USB, so you rarely run out of power during a day of shooting. The kit is presented as a practical power solution rather than a premium OEM alternative, and the reviewer found it most useful where convenience and extended runtime matter.

Key Features

• Extended Shooting Power: Each 1500mAh battery increases available runtime so photographers can shoot longer without swapping to the camera charger.
• Triple Charging Convenience: The included three-slot charger charges all batteries at once via USB-C or Micro USB to cut downtime between sessions.
• Wide Nikon Compatibility: Works with Nikon bodies that accept EN-EL14/EN-EL14a batteries, covering many entry and mid-level DSLR models and select Coolpix cameras.
• Flexible USB Input: The charger accepts power from a wall adapter, car charger, or power bank, which is useful when mains power is not available.
• Built-in Safety Protections: Overcharge, overvoltage, overcurrent, short circuit, and overheating protections reduce risk during repeated charging cycles.

Who It's For

This kit is best for amateur and enthusiast photographers who use Nikon cameras that accept EN-EL14 series batteries and who need extended shooting time for events, travel, or long days in the field. It is also a sensible purchase for videographers who shoot long clips and want multiple charged spares ready to go.

It is less suitable for users who require strict OEM battery validation for professional service plans or for those whose camera shows known compatibility limitations; a few users report that some bodies may not accept third-party cells, so double-check acceptance on your exact model before relying on these as your only power source.
