    I have bought X98 Air 3G Dual boot with 64 GB eMMC. Everything is perfect except the charging. First it took me almost 16 hours to charge the tablet first time using original charger. The 2nd time, original charger stopped working at all. I am using now my phone charger with micro USB male – Low amp output but at least it charges. Again, it takes forever to charge the tablet. What is the solution please?

    A. Kapasi,
    I, too, recently bought the 64GB model and I am having a similar problem. I found that my charger was getting excessively hot while charging the tablet. At first I thought I had a defective charger, so I bought a different 2.5 amp charger on sale at Frys.
    My new charger is also getting excessively hot.
    This is generally an indication that the battery bank is drawing more power than is available. I was thinking about trying to find a higher amperage charger, but you don’t find too many rated above 2.5 amps.
    Your smaller charger probably has some protection circuit built in so a device can not draw more than the charger’s rated power.
    I will let you know what happens with a bigger charger.

    Hi,
    I am using Samsung galaxy 2.0A charger since beginning. I didn’t tried the teclast original charger. I have no problems till now regarding charging. However it took some 5 hrs to get fully charge. I read in some forums that the lipo battery takes some initial charging cycles to get into full potential. Please correct me if wrong.

    FYI.
    One other thing that I am noting is that I am constantly getting the following message in Android:

    Throttling brightness due to thermal event

    Anyone else getting this message ?

    Did anyone get an answer to this?
    I’ve had an X98 Air 3G (Dual boot 64Gb) that has recently developed a charging issue similar to the one mentioned above.
    I’ve been searching the web & found a number of references to tablet charging issues, but nothing so far with a proposed solution that exactly matches my symptoms.

    I’ve found that I can charge OK if I shut down Windows, or have Android running, so it’s got to be related in some way to the OS config, or the drivers. Android seems so well behaved (you can almost see the battery meter climb when charging with an active session & it hardly looses any power when in standby all day, so it cannot be the hardware (at least not just the HW).

    With Windows running in connected standby, it sometimes charges (slowly) & sometimes drains completely ending up discharged & hibernated.
    The sleep study utility suggests it tends to use about 1-1.5 watts constantly, with relatively little difference between active & standby periods, yet it does not clearly indicate (at least not to me) what is the issue. The main activity reported whilst in connected standby mode is (not surprisingly) the WiFi HW at up to 3%, but with very low packet counts, so I’m at a loss.

    Anyone solved this?

    Most if not all of these Chinese tablets come with garbage chargers, it’s highly recommended to get a good quality genuine OEM Samsung, Lenovo or 3rd Party Anker, Aukey or even Monoprice charger.

    The charger on tablets acts like a power supply on a computer if the power supply is not providing clean power to the device chances are it will eventually damage the device or internal components over time.

    Personally, I would not use a generic Chinese charger unless it’s for review purposes and only for a very short period of time.

    I also bought a 3A. 5V charger but the problem is still the same…

    My issue is that charging well under windows BUT charging as SLOW USB CHARGE when on Android… And a good charger 3Amp did not solve that issue….

    Maybe need 5.3 V charger ? Can you please anyway send the link where you bought your charger on photo please ?
