Kastar 4-Pack EN-EL25 Dual LCD Fast Charger and Batteries - Long Life

In this review the Kastar 4-Pack battery and AC LCD dual fast charger is judged as a practical kit for Nikon Z series users who need reliable spare power. The package combines four replacement 7.6V lithium-ion batteries with a dual-slot LCD charger that supports AC 100V-240V and DC 12-24V input, so photographers who travel or shoot for extended periods get a straightforward power solution. The single biggest reason to consider it is the combination of capacity and the intelligent charging display, which makes managing two batteries at once easier than swapping blind into a mirrorless camera.

Key Features

• Battery Type: The 1320mAh lithium-ion cells provide a practical balance of runtime and size for Nikon EN-EL25 compatible cameras.
• Dual Fast Charger: The LCD dual charger charges two batteries simultaneously and reports charging status and capacity for better on-the-go battery management.
• Wide Input Range: AC 100V-240V and DC 12-24V compatibility means the charger works internationally and with in-vehicle power sources.
• Smart Control: An MCU identifies battery voltage and applies CC/CV charging with pre-charge and 0V activation to protect and extend cell life.
• Practical Outputs: The charger provides DC 8.4V at 1000mA per slot, offering relatively fast, reliable charging for two batteries at once.

Who It's For

This kit is best for Nikon Z series shooters who use EN-EL25 batteries and want multiple spares plus a compact, intelligent charger for trips or event coverage. The combination suits casual to semi-pro photographers who value an easy way to monitor charge status without carrying multiple OEM chargers.

Photographers who require official manufacturer batteries for warranty reasons, or those needing higher capacity professional batteries with certified lab testing, should compare alternatives. Also, expect basic plastic build and third-party branding rather than an OEM finish.

Pros & Cons

Pros

• Includes four replacement EN-EL25 batteries so users have extended runtime without pausing to recharge.
• The LCD dual fast charger clearly shows charging status and battery capacity for both slots simultaneously.
• Wide AC and DC input voltages make the charger versatile for international and in-vehicle use.

Cons

• These are third-party replacement batteries and not OEM units, so buyers should accept that distinction.
• The capacity is moderate at 1320mAh, which is useful but not a dramatic increase over some stock batteries.
