Check to see if it's charging
You should see a dim flashing LED when charging, and a solidly lit LED when fully charged.
Flip the Duet Flex when plugged in
This product can fit into a USB port facing either direction, but only one direction will charge it. There should be a light under the power button when it is plugged in correctly.
Check the USB port
Please try at least one other USB port on a different device or charging adapter.
Charge it overnight
Once the button light is pulsing, leave it to charge fully. When a rechargeable battery sits unused for a long period, it can slowly lose charge, and may take longer than normal to recharge. It can also lose its capacity entirely, so be sure to always recharge your products when you're done with them.
Check for Travel Mode
Press the power button to turn it on, then press and hold the power button for a slow count to ten. IT should stop (keep holding!) then pulse once. You are now in Travel Mode! Press and hold again to return to normal function.
