Use the compact and convenient Portable Charging Case with 4-Pack AAA and 4-Pack AA Rechargeable Lithium-Ion Batteries from iVANKY to run power-hungry devices. This charging case outputs 1.5V to charge up to eight batteries and trickle charges when they are full. A light indicator for each battery shows you a blinking green light during charging and a steady green light when fully charged. When inserting a battery in a power loss state, the charging case automatically reactivates it by using a low current to recharge it.

They are also IP67 waterproof certified, ensuring no leakage from the splash-proof battery housing design. With a lifecycle of up to 1200 charge cycles, the included batteries are long-lasting and help to reduce battery waste over time.
