I had my speaker and charger in my lunch bag…a bottle of milk spilled on the power adapter and shorted it and is no longer working…. When I charge my speaker without the original power adapter…it takes 10 times longer to fully charge….why?
Check the wattage of original charger. Just because it fits doesn’t mean it will work correctly. For example some old iPhone usb adapters are only 5 watt. Or half an amp. Most likely you need a 2 charger for your tablet. Most larger phones even take 2amp now.
Usually the power adapter you are using has a low wattage. A 10.5 W connection (2.1A) may seem too low. A 15.5 W connection (3.1A) may be more helpful and upgrading to an 18 W (3.6 A) or 20 W (4A) connection may help with charging speed.
It takes so long because the original charger is a very high-power charger. It’s much more powerful than any other charger you’re likely to have or find.
