DrPhone PSO1 Solar Energy Solar Powerbank 50000mA with Torch - 4x USB A 5V/2.1A & Input 5V 2A (Micro USB & USB C)

Solar Charger Power Bank: 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 solar charging as a backup option when other power sources are unavailable. The solar charging function may not be efficient enough on cloudy days, rainy days, and on weak sunlight days. 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.

50000 mAh large capacity: the 50000 mAh power bank can charge an iPhone / Samsung and other brands several times on one charge.

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

4 output and 2 input ports: the solar charger is equipped with 4 output ports and 2 input ports, including 1 type C input port and 1 micro input port. The power bank for electronic devices can charge 4 devices simultaneously. It is compatible with most smartphones, earphones and other devices.

3 light modes LED torch Bright mode / low light mode / strobe lamp: the solar power bank is equipped with an LED torch. 3 light modes. Double press the on/off button to activate bright mode. Then press the button again to switch to low light mode and then press once more to go to strobe mode. Double press the button to turn off the light in all modes. A must-have for camping, hiking, long trips and home emergencies.

LED indicators during charging and remaining power recognition 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 the portable battery charger is charging via a cable.

Important notes:
1. Fully charge it the first time before use. Read further in the note what you should adhere to during charging.
2. Please do not charge it all day, nor overcharge.
3. The best operating temperature for a solar charger is -14°F-140°F. For safety reasons, do not place it in a parked car or other high-temperature environments.
4. It is not allowed to be taken on a plane.
5. 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 a maximum of 2A.
6. Do not charge the item with fast chargers. This will reduce battery capacity or cause it to stop working in the long term. Always use the correct amperage. For this power bank, the output is 5V 2A. Do not exceed this!
7. Not approved by airlines due to high capacity 185Wh/50000mAh 3.7V.
8. The portable charger weighs 877G. It is not lightweight but quite heavy. Keep this in mind as it is quite bulky.

Explanation about mAh:
Difference between battery capacity and actual capacity
One third of the capacity is lost. The technical explanation is complex, 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.

The reason power banks have two thirds of the stated capacity is largely because the power must be converted. For example, the battery voltage of the power bank is 3.7 volts, but to charge a smartphone or tablet the power bank must boost the voltage to 5 volts. By boosting that voltage, from 10,000 mAh only 7,400 mAh remains, a quarter less. This applies to every power bank, regardless of capacity or quality. During charging, about 10 percent more energy is lost. That 7,400 mAh then becomes 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.

F.A.Q (most frequently asked questions)
Question 1: Is the 50000 mAh at 5V or 50000 at 3.7V? Many power banks advertise themselves on this, but it is usually 3.7V. Is this the same here?
Answer: If you see mAh always divided by 1000 to get true Amp-hours, which is the actual unit you need to know. This charger has a stock of 50 Amp hours. (Which is very good for this type of charger) Each terminal port delivers 2 amps per hour, at 5 volts.
What this means is:
1. Do not connect camping gear that uses 12 volts, such as a fan, etc. Use it only with items rated at 5V, like your phone etc.
2. If your phone draws 2 amps per hour, you get a total of 25 hours of charging power in a crisis, BUT you only want to use 80% discharge capacity so you don’t wear out the battery. So 80% of 50 Amp hours is 40, so a 2 amp per hour charger gives you 20 hours charging time with ONE port.***If you use all 4 ports at once, you must divide the total by 4, that is 6.25 hours at maximum discharge, or 5 hours at 80% discharge.

Question 2 : Do you know how many charges it can give a GoPro9?
Answer: The GoPro10 battery has a capacity of 1720 mAh. Let’s round that to 2k, then the 50k mAh power bank would give you 25 charges. Actual performance may vary.

Question 3: Is the battery capacity divided with 25000mAh batteries in one casing? Do you have to charge both inputs separately or can you fully charge the device with just one?
Answer: The solar power bank has two inputs. Either the Android and type-c ports can charge the power bank. The built-in 4 USB ports can charge any iPhone and iPad.

Question 3: Does this work for the Samsung Galaxy Tab S3 tablet?
Answer: Yes it does!

Question 4: Will this charge an iPhone 10 and iPhone 11?
Answer: The solar power bank is a good device for charging your iPhone 10 and 11
