DrPhone KL1 – Powerbank 20000mAh 3.7V 74Wh – Qualcomm 3.0 – PD 3.0 (Power Delivery) – Smart LED Display – Black

Smart LED display: The digital display of the KL1 can show both the input and the output. These can be displayed with different options such as;
-DC fast charging display
-QC3.0 fast charging display
-PD fast charging display

Wide compatibility: The power bank has wide compatibility because it offers multiple options for both Qualcomm 3.0 and PD 3.0. It can support devices such as:
- USB PD Fast Charging Power Bank for iPhone 13,12,11 PRO/PRO MAX/Mini /XS Max XS XR 8 8 Plus and more.
-USB 3.0 Power Bank for Huawei Mate 40/30/20 20 Pro / P40/P30 and more.
P20 Lite Plus
- USB 3.0 Powerbank for Xiaomi Mix 3S Mi8 Redmi 6 Pro Note 5 Pro and more

The power bank supports not only Qualcomm 3.0 and PD 3.0, but also QC2.0, AFC, FCP, PE +, apple2.4, BC1.2 and other various fast charging protocols.

20000mAh high capacity: The large capacity of the 20000 mAh Powerbank allows you to charge your smartphones and tablets multiple times. Despite the large capacity, the compact power bank weighs only 368 grams. It easily fits in any pocket or bag, making it the perfect portable charger for travel, on a plane or anywhere your phone needs charging.

Charge three devices at the same time: Dual USB 3.0 + type-c PD three-port output meets all requirements and needs to charge 3 devices simultaneously.

Note that when multiple devices are charged simultaneously, this affects the charging speed and the fast charge function will not work.

What is the PD fast charge protocol?

PD fast charging is a new charging technology protocol, which has a stronger power transmission capacity (100W MAX) and faster transmission speed (10Gbps Max). It also supports the reversible function. It is the new way of charging for the future.

Qualcomm 3.0 & PD 3.0 Fast charge: The Powerbank with a PD 3.0 USB-C port and 2 x QC 3.0 ports for simultaneous charging of 3 devices with combined power. The calculation is as follows:

3 inputs (input) + 3 outputs (output)
Output:
USB 1:DC 5V /3A 9V / 2A 12V / 1.5A Max (Qualcomm 3.0)
USB 2: DC 5V /3A 9V / 2A 12V / 1.5A Max (Qualcomm 3.0)
Type C:DC 5V / 3A 9V / 2A 12V / 1.5AMax (USB PD Fast Charging Port)
USB 1 + 2 + Type C : DC 5V / 3A Max (simultaneously)
Input:
Micro USB:DC 5V / 2A 9V / 2AMax
Type C:DC 5V / 3A 9V / 2A
For Lightning: DC 5V / 2A Max

100% safe protection: The portable Powerbank uses high-quality Li-polymer batteries, together with multiple intelligent protection technologies, such as; temperature protection, output short circuit, reset protection, input voltage protection, output voltage protection, metal foreign object protection and more.

Explanation about mAh:
Difference between battery capacity and actual capacity
One third of the capacity is lost. The technical explanation is complicated, but the rule is simple: the actual capacity of a power bank is about two thirds of the stated capacity. The rest disappears during the conversion of the current or is lost during charging, especially as heat. Power banks with a battery of 10,000 mAh or 20,000 or 30,000 mAh therefore actually have only 6,660 mAh or 13,330 mAh or 17,500 mAh capacity.

The reason power banks have two thirds of the given capacity is largely because the current must be converted. For example, the voltage of the power bank battery is 3.7 amps, but to charge a smartphone or tablet the power bank must increase the voltage to 5 amps. By increasing that voltage, only 7,400 mAh remains from 10,000 mAh, a quarter less. This applies to every power bank, regardless of capacity or quality. During charging, about 10 percent of the remaining energy is lost. That 7,400 mAh is then only 7,400 x 0.9 = 6,660 mAh. Much of that energy is lost as heat: that is why your smartphone often gets warm during charging.
