What to do if my POWERWIN BT5120 cannot be charged?
If the POWERWIN Battery Pack isn't charging, first ensure the charger output plug is firmly connected to the battery. Also, verify you're using the correct charger. If the battery is already fully charged, it's ready for normal use.
Why does my POWERWIN BT5120 Battery Pack have no output?
If your POWERWIN Battery Pack has no output, make sure the output cable is properly connected according to the specifications. If that's not the issue, the battery pack might be dead, and you should charge it.
Why is the charger indicator off when charging my POWERWIN BT5120 Battery Pack?
