Whatever you do - More Hardware consumes more power. So you better look out for something with USB-C and Quickcharge/Turbocharge so you get more than 5W into your device (5Volt * 1Ampere). https://en.wikipedia.org/wiki/Quick_Charge I am using a Moto X4 (LineageOS) and i dont have any problems like this. (Using a QuickCharge cigarette lighter adapter) And you can do the math. Lenovo Tab 2 with a 30 Watt/hour battery is rated for average 10 hour operation. Thats most likely a very optimistic runtime, mostly idle, surfing the web. So in Idle the tablet consumes at least 3 Watt - Using OSMAnd, GPS etc will go above the 3 Watt. Without any more sophisticated power solution than standard USB you drain the battery although beeing connected. USB does 5 Volts at 1 Amp with standard chargers and devices - thats 5 Watt.
