DrPhone PSO2 Solar Energy Solar Powerbank 20000mA with Multifunctional Torch & Wireless Qi Charger – Universal – Black/Green

Solar Energy Charger Solar: the solar panel on the power bank can collect solar energy all day in direct sunlight. Please note that solar charging is an additional feature and consider the solar charging option as a backup solution when other power sources are not available. The solar charging function may not be efficient enough on cloudy days, rainy days, and on a weak Sunday. Make sure the solar power bank is fully charged before you travel. This could be on holiday, going to work, or sitting at home where there is no nearby power outlet.

20000 mAh capacity: the 20000 mAh power bank can charge an iPhone / Samsung and other brands several times with one charge.

Note: This is for indication only. Actual capacity may be less. It is tested based on all present elements and specific situations. Because it is a 5V power bank, it takes almost a whole day to fully charge the power bank.

3 output and 2 input ports: the solar charger is equipped with 3 output ports and 2 input ports, including 1 type C input port and 1 micro input port (cannot be used simultaneously). The power bank for electronic devices can charge 3 devices at the same time. It is compatible with most smartphones.

Note: The power bank must be fully charged to use all 3 ports for simultaneous charging

5W Qi Wireless Charger: On the back of the power bank you also have an option to charge wirelessly. Place your smartphone that supports wireless charging on it and your phone will start charging spontaneously with a wireless connection. Please note that this is a stable charge and not a fast one. The Qi supports max 5V 1A.

3 light modes LED flashlight Normal mode / SOS / Warning mode: the solar power bank is equipped with an LED flashlight. 3 modes. Press the on/off button twice to activate normal mode. Then press the button once more to switch to warning mode and press once more for the last time to go to SOS mode. A must-have for camping, hiking, long trips and emergencies at home.

LED indicators during charging and to recognise the remaining power of the Powerbank:

-1 LED indicator: 1% -25%
-2 LED indicators: 26% -50%
-3 LED indicators: 51% -75%
-4 LED indicators: 76% -100%

The LED indicator lights up when you turn on the power bank via the power button on the side.

IP54 waterproof and portable design: The waterproof rating is IP54, splash-proof and dustproof. The casing of the solar charger is made of ABS material for environmental protection, strong and durable.

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 is lost during power conversion or charging, especially as heat. Power banks with a battery of 10,000 mAh or 20,000 or 30,000 mAh actually have only 6,660 mAh or 13,330 mAh or 17,500 mAh capacity.

That power banks have two thirds of the stated capacity is largely because the power must be converted. The voltage of the power bank battery is for example 3.7 ampere, but to charge a smartphone or tablet the power bank must increase the voltage to 5 ampere. 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 of the remaining energy, about 10 percent is lost during charging. 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.

Important notes:
1. Charge it properly the first time before use. Read further in the manual notes about what you must adhere to during charging.
2. It is not allowed to take this in the car during strong sun. The heat that can build up in the car can damage the battery.
3. Do not use solar energy as the primary charging source. Solar charging is intended for emergencies. In daily life we strongly recommend charging it via a charger with max 2A.
4. Do not charge the item with fast chargers. This causes the battery capacity to decrease or to stop working in the long term. Always use the correct ampere. For this power bank the output is 5V 2A. Do not exceed this!
