Wide support for 18650 Li-ion Batteries (Applies to TOMO and Epilot)

Quality terminals were designed to ensure compatibility for both 18650 flat-top and button-top cells.


You may also mix and match different cells. It will charge them separately with no issues even they each has different voltages. It will also fit the longer protected cell shown in the leftmost slot. When the cells are fully charged, you may easily remove them to power your Flashlight, Portable Fan or other devices. On the other hand, if you are rushing to go outside, simply slide to close the lid cover and it immediately transformed into a power bank. The total capacity of the power bank can be calculated by adding up the capacity of the individual cells. It will be ready to charge your mobile devices while you are on the move. How convenient it is !!! In terms of function, it is basically buying a charger and get a power bank at no extra cost!

Quality electronics with safety

A: Four SS32 Schottky diodes ensure that the batteries keep similar voltage during discharge to prevent damage to the cells due to currents flowing among them caused by dissimilar voltages. It also protects against damaging the device and battery when the battery is reversely inserted.
B: Highly efficient tantalum filter capacitors filter Direct currents to produce smoother and more stable output to charge or power your USB devices.
C: Highly efficient inductor is used in the filter circuit.
D: Four dedicated TP4057 charge management IC for each slot to charge the inserted batteries independently to ensure maximum safety.
E: 9926A MOSFET to regulate and provide a stable combined total output of 5V/3A for the two output USB ports.
F: PIC16F1933 micro-controller to drive the LCD and manage the whole system.
G: MT5032A Synchronous Boost Converter to boost 3V-4.2V to 5V for USB output ports.
