I follow Gahrling recommendation if nothing else then its a easy, cheap fix.
The stock USB cord for the Paewang isn’t that well made anyways.
When trouble shooting you always want to go in order from the most easy and simple, and cheap Fixes first and work your way down to harder, more complex repairs/causes.
Like on your car, got engine trouble. Check the oil first, if the engine oil level low, fill the oil up. If the issue gone then it was just the oil level.
If their a puddle under your car afterwards, then your oil is leaking. If you do not have issues with the oil, check the mileage you might be due for a oil change or a tune up.
And you work your way from there.
