KHOI1971 USB cable data transfer charger for MATSUNICHI MARQUIS MP977 tablet 2-PIN DUAL CHANNELS 2X SUPER FAST CHARGING ( CUSTOM MADE like OEM cable ) I have some feedback that it need to use with a 5V 2A usb charger, if the battery is not charge for a long time it will go into a deep sleep freeze ( reset the table after 30 minute of charging might wakeup the deep sleep freeze ) IMPORT make sure to PRESS HOLD the CLIP RELEASE when insert or remove the connector Make sure the plug is not upside down or backward when plug into the port and the alignment to the port Make sure turn off the unit when charge
