I have a 1.8m cable ordered to tablet load and measured the power, as it takes longer than the original cable but that only uncomfortable 50cm long is this ... 1.8m cable allows a charging current of about 1,1Ampere , Short cables can be on the same adapter by over 1.7 amps. Thus, the tablet (Cube Talk 9x) is overnight (unless you sleep long * gg *) to this cable not fully charged, even when using a power loader. LG
