Charger Nitecore Newell TT-USB-C three-channel charger for Nikon EN-EL15 batteries

The Nitecore Newell TT-USB-C three-channel charger for Nikon EN-EL15 batteries is a compact multi-bay charging solution that accepts up to three EN-EL15 cells and charges them independently via a USB-C power input. Designed for photographers who carry multiple spare batteries, the charger provides simultaneous charging with individual channel monitoring and automatic detection of battery status, allowing effective management of camera power on location or in a studio setting.

Advantages

The charger supports three independent channels so each EN-EL15 battery can be charged or rested without affecting the other bays. USB-C power input enables use with common USB-C power adapters or power banks for greater portability. Built-in monitoring on each channel prevents overcharging and indicates charge status per cell, helping to preserve battery health and provide predictable charging times.

Suitable for

• Photographers who use Nikon cameras powered by EN-EL15 batteries and need to charge multiple spares.
• On-location shoots where USB-C power banks or USB-C adapters are used to recharge batteries away from mains power.
• Studio workflows requiring predictable, independent charging for several camera batteries at once.

When it may not be suitable

This charger is specific to EN-EL15-format batteries and is not suitable for battery types with different sizes, voltages, or contact arrangements. If you require a universal charger for many different battery chemistries or sizes, a model supporting additional formats would be more appropriate.

Key specifications

• Number of independent charging channels: 3
• Supported battery format: EN-EL15 series (Nikon)
• Power input: USB-C
• Individual channel monitoring and status indication
• Simultaneous charging capability
• Compact, transportable form factor

How to use

Insert EN-EL15 batteries into the charger bays following polarity markings. Connect a compatible USB-C power adapter or power bank to the USB-C input and switch on the power source. The charger will detect each battery, start charging independently per channel, and indicate the charge status. Once a battery reaches full charge the charger’s monitoring circuitry will stop charging that channel to avoid overcharge. Remove batteries after charging is complete and disconnect the USB-C power source when not in use.

What to consider before purchase

• Confirm compatibility with your battery model—this charger is made for EN-EL15 series batteries.
• Ensure you have or plan to use a USB-C power adapter or power bank with adequate output for multi-channel charging.
• Check physical dimensions if you need a compact charger for travel or small camera bags.

Usage recommendations

For reliable field use, pair the charger with a high-capacity USB-C power bank that supports sustained output; charge batteries individually or in groups as needed and store batteries at recommended storage charge levels when not in frequent use.
