Low Current 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.

The basics behind the batteries used in portable electronic devices: LiPo, NiMH, coin cells, and alkaline.

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.

  • There is a note on the datasheet

    Lowest Output <20

    Is there any limit the battery switchs off? A lot of deep sleep devices consume less than 1 mA! I'm searching for a USB chargeable battery pack that does not switch off on any current. Is this the case for this device?

    • Also would also like to know the answer to this--

      Can the battery supply do a short deep sleep if the wake up meets the 20mA ?

  • Can this provide power while it's charging? I use that setup for backup power for small devices (clocks and such), but not all USB battery packs can operate that way since designers often save money by sharing the power converter between the two functions.

  • You indicate that this is a 2.5 amp-hour pack but the pdf you point at sez 2200mA-hr. Did I miss something here? Thanks!
