Product Information
Your job can be incredibly busy. When you’re running around town from meeting to meeting, the batteries
on your digital assistants can drain quickly. Stay charged while on the go with the PowerKeep™ PRO
backpack from Energizer®. We recommend charging your PK10K power bank before you leave home.
Then, when you are on the go, use the PowerKeep solar panels, a USB charging port or a wall outlet to
recharge the PK10K power bank that comes with your PowerKeep PRO.
How to charge the PK10K power bank
The PK10K can be charged three ways: by the PowerKeep portable solar panel, a USB charging port
or a wall outlet. No matter which way you choose, the steps are the same.
I). Use the micro-USB cable to connect the PK10K input port to a charging port, a wall outlet or to
the output port of the solar panel.
When charging the PK10K from the wall, you will use the same wall transformer that came with your
device (i.e. smartphone). We don’t include a wall transformer because most devices already come
with them.
II). During charging, the LED power indicators will blink. A blinking light indicates charging and a
solid light indicates fully charged.
III). Once charged, four (4) solid LED lights will indicate the PK10K
is fully charged.
How to charge your USB device, such as a smartphone, with the PK10K:
Use the charging cable for your smartphone or USB device and connect the device to either output
port on the PK10K.
How to charge your USB device, such as a smartphone, with the PowerKeep solar panel:
Use the charging cable for your smartphone or USB device and connect the device to the output
port on the back of the solar panel.
