Review on Beffkkip Discharge Integrated Charging Boosting by Paul Dye

Using a 18650 battery in the battery port and a 5V inductive charger (or any 5V source here) in the charge port it charges 18650. 4 LEDs is good . Each represents 25%. When your low battery starts to charge, the first LED (25%) will flash until the battery is over 25% charged, then it will light up and the next LED representing 50% will flash, after 50% charge it will light up. you have the idea As soon as all LEDs light up, the battery is fully charged. Auto on/off is ideal as long as your load is above 50mA. With no load, zero is drawn from the battery. If you connect a load over 50mA to the output pattern, all the status LEDs will light up to show you the battery level and you'll get a good 5V output. Works great for wirelessly charging an RGB lightsaber, a 18650 battery and an inductive charger from Adafruit https://www.amazon.com/gp/product/B00SLYAIG8/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
