(Note: the user guide may be bigger in new purchases.)

You should see a short 1ft. cable that is either black or white depending on the color of your PowerPack. This 1ft cable is stuffed in a small side compartment next to the PowerPack compartment. It should be inside a plastic sleeve or pouch. This short cable is used to recharge your PowerPack only. It is not intended to charge your iPhone or Android smartphone. However, there are a few compatible devices that the short cable will charge; please contact us ( for more information.

Plug the smaller end into your PowerPack's micro-USB port, the one closest to the lights. Plug the larger, rectangular end into a USB wall charger/power adapter. For more detailed instructions on recharging: read this guide that goes step-by-step with images.

Some customers may try to use their own micro-USB cable. However, this may produce some unintended results. The PowerPack may recharge much slower than normal and take more than 12 hours to fully recharge. If you are experiencing issues recharging, first make sure you are using the ZMI 1ft recharging cable/cord. This will help ensure that the battery pack gets recharged quickly.
