Digital Display Screen – Accurate display of power, keep the Battery Status at any time.

Function: power bank and rechargeable 18650 battery charger.

QD188-PD battery requirements: standard 18650 lithium battery (to use power battery), to use a new imported or domestic big-name battery (because the battery structure of the power box is 2 and 4 strings), so the battery consistency requirements are very high, The battery voltage must be the same before putting the battery into the battery. Otherwise, the battery will be uneven and various problems will occur.

Only use standard 18650 batteries;

The pointed battery is a modified size that is not completely standard for the 18650;

With the protection board battery, the size has also changed. The current protection board current is only about 2A. It is not enough. The minimum threshold for the power box is used. This battery is also used in flashlight lighting.

Because this power box is high-power; and it is a series relationship (2 and 4 strings), so the consistency requirements for the battery are relatively high; it is necessary to place 8 new A-type batteries of the same brand with the same model to work or not.

Input charging management interpretation; the optimal voltage for input to the power supply box is 18V-20V (PD protocol best 20V 2A) because the internal battery of the battery box is 2 and 4 strings (the series can increase the power output efficiently and the notebook is also the same as the high voltage charging year) Routine cost is high), unlike conventional mobile power, the battery voltage of the conventional mobile power supply is 4.2V full, so it is enough to use 5V; this is a 2 and 4 string battery arrangement, the internal battery voltage is 16.8V, then it needs to be higher than this voltage to charge it; if you charge it with 5V, then the power box should boost 5V to 19V and then charge the power box. First of all, the loss is very large, remove the loss. The remaining zero point A is barely throwing a current to recharge it (for example, the notebook is rarely useful for 5V charging), the larger the differential pressure is, the greater the loss, the low input power meter circuit is difficult to maintain normal. Full power operation status, display refresh is not timely, but the internal hardware charge management chip will automatically disconnect the current if it meets the charge saturation requirement and then the percentage will be changed to 100%. Also supports 5V to 16.8V or less convenient for everyone to compromise only compatible (if the phone now 18W quick charge will be much better than 5V).

Compatible For iPhone X 8 7 6 plus/6/5S,for ipad,for Sam-sung Ga-laxy S8 S7 S2/S3/S4, Note 2/3/4, HTC, for So-ny, Xiao-mi for Motorola and other cellphones or tablet

With a USB to Type C cable,you can charge the An-droid cellphones or tablet with Type C port.

Need to use the new 18650 battery of the same capacity and model, can not use different brands of batteries
