Some power banks and many USB battery
Some power banks and many USB battery packs switch off (go into a sleep mode) if the current being drawn is too low. This means that your device works for a few minutes and then stops. Often just a few extra milliamps current draw will keep the battery pack alive.
There are various circuits on the web that give a pulsed load which works with some battery packs - but unfortunately SOTAbeams' tests have shown that such circuits don't work reliably with all battery packs.

Just plug one of these Keep-Alive Load Kits into your battery pack and increase the current until battery pack stays on reliably (usually between 6 - 150 mA). Depending on the current that your powered device takes it may be a little as a few milliamps. An on-board LED indicates if the battery pack is live. The load supports a standard USB data connection. USB plug and socket for easy in-line connection. A heat-shrink sleeve is provided to protect the unit in the field.
