Extended Power for Nikon EN-EL15c Users

This kit integrates a 7.27V 6800mAh power bank into a dual-slot charger case built specifically for Nikon EN-EL15c batteries. It accepts both original and third-party cells, making it a flexible solution for photographers who need reliable energy away from wall outlets. The internal bank can also top up smartphones or other USB-C devices while you shoot.

Thermal Range and Charging Speed

Operation is rated from 0°C to 45°C during charging and from -18°C to 60°C when discharging, so the unit remains functional in cold mornings or warm afternoons. The USB-C port delivers up to 36W and supports PD3.0 and QC2.0 protocols for rapid replenishment. Two depleted batteries reach full capacity in roughly 2.5 hours, while refilling the power bank itself takes about 3.5 hours.

Built-In Cable and Real-Time Display

A fixed USB-C cable is stored inside the case, removing the need to carry a separate cord for input or output. The high-definition screen shows the charge level of each battery slot and the power bank itself, even when the unit is unplugged. When any cell drops critically low, its icon flashes to give an immediate visual warning during a session.

Questions about this item

How do I insert the two Nikon EN-EL15c batteries into the dual slots and what is the step users often miss?

Slide each battery into its labelled channel until it clicks; the step often missed is pressing the power button to start charging, otherwise the display stays dark and nothing charges.

What maintenance will the internal 13,600mAh power bank need over time?

Recharge the power bank at least every three months during storage to prevent deep discharge, and keep the USB-C port and built-in cable free of dust for reliable contact.

What thermal limit stops charging first during sustained use in hot conditions?

Charging halts when the case reaches 45°C, while discharging continues up to 60°C; the 0–45°C charge window is the first limit hit under heavy load.
