Lenovo Tab A7-40 Power Adapter
When purchasing a replacement AC charger, selecting the Lenovo OEM charger is the best one to choose. The Lenovo Tab A7-40 power adapter is needed for two reasons, to charge up the main battery while simultaneously providing power for the tablet. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. A universal power adapter is another possibility if yours is unavailable or backordered. Because Lenovo has been known to use a single AC adapter that is probably used on other similar units, be sure you choose the right one.
What warnings are present when my Lenovo power adapter is not working right?
- Your Lenovo battery refuses to charge completely
- The unit will not function without the battery installed
- The majority of Lenovo power chargers can get quite warm when plugged in for 10 minutes or more
