Charge your Phone on the go in 2020
Your Phone is running out of power and there is no opportunity to charge it? No problem! In 2020 there are many ways you can Charge your phone without the need of a power socket. We present you the best mobile power sources for your Phone and Gadgets.
Powerbanks
Powerbanks have become very popular over the time and are used very often. When deciding what Powerbank to buy, it's important to know what you need.
There are three important factors: The Capacity, Output and Input current. Most phones have a capacity anywhere from 3.000mAh to 5.000mAh. A Powerbank with 10.000mAh should be enough to fully charge a phone one to three times. As mentioned above the Ouput and Input current are two more major aspects. They indicate how fast it can be (de-)charged. Here we recommend 2A for Input and Output
Solar Chargers
Solar chargers are rather new but they are perfect if you want to go hiking, camping or bicycling. The majority of solar chargers have a 5 volt output and can charge all your USB devices. Here just one number is important.
As with the Powerbanks the Ampere play an very important role. Down below you can see three of the best Solar cells we could find.

Charge your Phone on the go in 2020
Powerbanks up to 26.800mah
Powerbanks up to 10.000mah
USB Solar Chargers
The given capacity of a Powerbank is not the true capacity that can be used!
If you have a 10.000mAh Powerbank and Phone with 2.000mAh most people will think that you can charge your Phone 5 times. Thats wrong, but why?
--> Powerbank and Phone batteries have a voltage of 3.7V and not 5V. For transfer the voltage is transformed to 5V and then back to 3.7V. This leads to a loss about 15% and in addition the powerbank will stop charging with 15% left in it due to safety reasons.
The same thing goes for Solar Chargers. All Solar Panels have a given watt number. This amount is called Watt Peak (kWp) and was measured in optimal conditions so that's usually not the real amount of Watt.
Let's take the BigBlue 28W Solar Charger in our test it delivered a maximum of 3.7A at 5V that is 18.5W and not 28W as you might expect that it will deliver.
So in most cases the amount of watt that is given in the name of the Solar Panel is not going to be the real amount.
