Hello, as you may be aware by now, this tablet consumes a lot of power. The Intel Atom CPU can need up to 8W and the screen is big and draws power too. That’s why the charger that comes with the tablet is a 2.5A one, and the USB cable is short and thick.
You need a charger capable of providing at least 2.4A, there are a lot of those. And you need a USB cable capable of carrying that current without much resistance. And here we have to apply what we learned on school about Ohm’s law. The resistance is proportional to the length of the cable and inversely proportional to its thickness.
For a 2 meter (6 ft) cable you need it to be made with thick copper wires. The standard way of measuring that is AWG. The USB cables we have been using to connect and charge cell phones have thin copper wires inside, classified as AWG28.
To carry more current to greater distances you need cables with power wires classified as AWG22, AWG20 or AWG18. I have three 6ft cables that have those specs and they can charge the tablet while I’m using it (a 5% in the time it took me to write this).
