Lithium Ion Battery Pack - 2.5Ah (USB)

We've taken the classic, portable, rechargeable lithium ion battery pack and tweaked the design to make it amenable to low current applications. While similar power banks are typically designed to power off automatically at lower currents, this battery pack will continue to operate if your device is drawing a mere 20mA and over! Just connect your device to the USB-A port on the battery pack and you're good to go! To recharge the battery pack, just plug it into your computer or phone charger using a USB micro-B cable (not included).

This particular battery pack has a 2,500mAh capacity and can source 1,000mA at 5VDC.

Note: This item may take longer to process due to battery installed in the equipment and therefore does not qualify for same-day shipping policy. Sorry for any inconvenience this may cause.

Shuts down at lower currents despite description

My devices run at 22ma and these battery packs (bought a bunch of them) shut down after 16 seconds.

Sigh. I'll be giving these away as gifts for friends and family with less precise needs.

Otherwise seems to function well, just not as advertised or as needed.
