My VIZIO Tablet 1008 micro USB charging port is looseand charging indicator comes on some times when I move the wires around. ow do I get to charge the Vtab?

Does it have a micro USB charger/charging port? This was the universal charging adapter most manufacturers other than Apple moved to around 5 years ago. In my experience, the charging port to charger connection can become loose and prevent charging....especially if you use the tablet or phone during charging. The best method I have found to troubleshoot the issue is to try a charger that successfully charges another device and plug it into the tablet or phone. If your device still does not charge, and especially if the connection is loose, it is most likely that your charging port is damaged. Another possible issue would be the battery itself but the charger or charging port is the most likely culprit for your issue.

Most common cause of this is faulty charger, the metal connector at end of wire won't connect properly to device charging port.
Test it by putting plug back in Tablet charger port and very very gently wiggle it around very slowly, see if the charging light comes on or flickers. They usually make a beeping noise when successfully charging or the screen lights up. If you get intermittent charging then it's the charger and time to get a new one. Very common, most are USB connectors or small pin types.
If it's still under warranty then send it back to the place you bought it before you try testing it.

Linda, if it is the charge port, mini USB, yes they can be fixed or replaced by cell phone/computer repair shop.
Check the attached links videos showing port replacement. Good luck.

Battery replacement is possible. The battery is a flat component encased in a shiny silvery sheath behind the speaker area inside the back cover. It's mounted with double-sided (very) sticky-tape. A replacemnent battery should be sourced, having the same power specifications as well as physical dimensions. (see detailed close-up photo attached.) Replacement involves desoldering the 2 terminal wires (1 red and 1 black) which attach it to the main board, and replacing the battery with a new(er) unit.
The above having been said,I'd only replace the tablet battery if I was sure that it's the battery at fault. Here's what I'd suggest.
First, check that you're using a charger with the proper 5 Volt / 2Amp (2000milliamp) output. Also I'd suggest you use a charger designed to be plugged intothe G2 7" Dual-Core tablet's dedicated charging port. (See sample tablet charger in attached photo) The G2 tablets WILL typically accept charging output via the micro USB port, for example, from a typical cell phone charger. However typical phone chargers which will happily attach to the Trio or other similar tablets, via the micro-USB port do NOT often have the same output power specifications. This I think may cause difficulty with the tablet battery not reaching the fully-charged status. Also, the use of the USB port for charging may cause access problems if the battery power is low during some operations (eg data transfer in slave mode), as the charging port can not multitask as the USB port can. If power to the main boad is lost during such operations the tablet may become "bricked". Bottom line for me would be to use the dedicated appropriately rated charger whenever possible: it's the reccommended charging method.

Try a different Micro-USB cable. It is usually caused by the cable's micro-USB end being loose and not the tablet's charging port. Most smartphones these days use Micro-USB so you can usually try using one of those if you have one.

The charging on the tablet depends on the model.
Most including the Kocaso 776 charge via the micro USB port, and this is a standard USB port.
So all you do is purchase a micro USB to standard USB cable and plug it into the standard USB port on the charger or a PC.

Yes it will :)

If you are using a USB port on a PC or Laptop think of trying a different USB port - sometimes they put out low power;
If your laptop or PC is more than 3 years old it probably can not put out enough power on the USB to charge a tablet (any tablet).

Check to see if any of your existing wall adaptors for (say) your phones have the same micro USB connection - use it to charge your Kindle - it's totally fine.

Go to any shop in the high street and buy a Micro USB wall adaptor, they start at about 5gbp. You can get them on Amazon too.

Remember it takes about 6 hours to charge from the wall and 16 hours (yes, 16) to charge from a computer usb.

Good luck
