We've revamped the classic, portable, rechargeable lithium ion battery pack for low current use. Unlike typical power banks that shut off at low currents, this one keeps running when your device draws as little as 20mA! Simply connect your device to the USB - A port on the battery pack. To recharge, use a USB micro - B cable (not included) and plug it into your computer or phone charger. This battery pack has a 2,500mAh capacity and can supply 1,000mA at 5VDC. Note: Due to the installed battery, this item may take longer to process and doesn't qualify for same - day shipping. Sorry for the inconvenience.


Using this battery pack is easy. First, find the USB - A port on the battery pack and connect your device to it. Your device will start getting power right away, even if it only needs a small amount of current. When it's time to recharge the battery pack, grab a USB micro - B cable (you'll need to get one yourself) and plug it into your computer or phone charger. Just remember, because there's a battery in this item, it might take a bit longer to get processed. So, it won't be shipped on the same day you order it. As for maintenance, keep it in a cool, dry place. Avoid dropping it or exposing it to extreme temperatures. This will help your battery pack last a long time and keep working well.
