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.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

  • Looks like a great little device except for the shutdown while charging: 7.1.4 The output will be shut down automatically under charging status. (from the data sheet)

    • Yeah, that would be unfortunate. The other power banks like this that I've seen (even the much cheaper ones) all allow simultaneous power input/output.

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.
