Tablet does not work anymore (in the store already)?

A few days ago, the battery of my tablet ran empty and when I plugged it to recharge, the charging process is constantly interrupted. Thought it would be a loose contact in the cable, so I bought a new one today. Because I wanted to make sure it was really on the cable, I let it hook up in the store and it loaded my tablet properly without breaking off. At home, however, it did not work again and the charging process stopped, even though I changed adapters and connected to the laptop.

So why was it in the store and not at my home? Other problem sources? On the adapter it's probably not synonymous.

On the laptop maybe. Try another power source.

I had written that I have tried on various adapters (ie for the socket), which work for the phone, as well as on the PC. The cable I bought today went in the store.

Was the laptop permanently on during charging? And was this also hanging on the charger?

If not, then it may well be that the USB ports are also switched off. This would of course interrupt the charging process.

Try it with another USB port on another device. Or buy yourself a USB power supply, which is suitable for tablet PCs, so has a higher charging current.

The laptop was of course switched on lol, but yes, he is himself "wired" because the battery is removed. The charging process stops after 1 second and restarts - regardless of whether it is connected to the laptop (USB 1 or 2) or to the adapters (1 + 2).

Ok, it was just a possibility that I wanted to exclude.

And with "adapter" I suppose, you mean a normal USB cable, or do you have something special.

There are also Y-cables, which then draw the power from 2 USB (2.0) ports. In the past, they were also used with external 2.5 "Pata USB hard disks.

USB 1.0 and USB 2.0 deliver a maximum current of 500mA. Can it be that the tablet may need more? USB 3.x delivers 4A.

It may also be that your laptop does not provide the necessary ampere power to the USB ports… It would be at least possible.

There are therefore special 220V USB chargers that deliver significantly more than 500mA:

What does this actually mean in the technical descriptions of the tablet?
