External battery for mobile phone guide

External rechargeable batteries, or even power banks or battery packs, are especially popular in this day and age, when the battery of a smart phone rarely lasts 24 hours a day. Thanks to an external battery for the mobileor SmartphoneIn the case of a very low battery level, you do not have to immediately search for the next power outlet or even switch off your smartphone. The accessibility is thus still given. Powerbanks can become true lifesavers.
The average life of an external battery is about 500 charging cycles. However, with good care and proper use, they can last longer. These include, for example, the correct charging – ideally always completely – as well as the correct storage. Especially hot or cold temperatures damage the energy cell. Leaving the external battery in the sun is therefore not a good idea. In addition, shocks and the like should be avoided.

The right external battery for the smartphone

With an external battery, mobile phones, smartphones but also tablets and Mp3 players can be charged up to four times; This is mainly dependent on the capacity of the battery pack.
When choosing the appropriate battery pack, the area of ​​application should be considered. If it serves only as an additional battery for emergencies, then a model with a smaller capacity is enough. For business trips or long flights, external batteries with a larger capacity are recommended.
The capacity of Power Bankshould be up to 20 percent larger than the cell phone battery. Charging causes an energy loss of 20 percent. Thus, it is still possible with a larger capacity to fully charge the smartphone. The capacity of a smartphone or cell phone battery is between 1,200 mAh and 2,000 mAh. It is therefore advisable to buy a battery pack with up to 5,000 mAh. We recommend models like the Powerbank RAVPower with 10,400 mAh, the Poweradd Slim 2 external battery with 5,000mAh or the Xcessory Slim 2 external battery with 5,000 mAh. The Powerbank RAV Power with 16,750 mAh is suitable for charging several or different devices. It has different interfaces and connection options.

Pay attention to quality

Especially with an external battery for the mobile phone or smartphone is to pay attention to the right quality. Inadequate technical features can damage the smartphone’s battery. Thus, for example, this could be severely damaged by a bad charge and lose power and stamina. The most important characteristics of external batteries are therefore their efficiency and their lifespan. In addition, they have sophisticated charging technologies that recognize the output voltage of the connected mobile device and take into account during the charging process. Especially the models of RAVPower, anchoror Easyacc are equipped with this technology.

External batteries for extreme applications

Most external batteries are not very robust. For climbing tours or outdoor activities, therefore, a battery pack should be chosen, which were designed for appropriate exertion. Models such as the RAVPower 10.050 mAh 3 or the EasyAcc® 15000mAh Solar, which can be charged via the solar cells in an emergency and a built-in flashlightincludes.

Are recommended here. Even waterproof models such as the EasyAcc 9,000 mAh Outdoor or the already mentioned RAVPower 10,050 mAh 3, which is dust, shock and waterproof, are especially useful for beach holidays or holidays on or on the water.

With an external battery, your own smartphone can always be charged in emergencies or on long trips. So you do not have to panic at the next outlet to go to a low battery level. It can be almost any smartphone, cell phone or tabletbe charged with this battery pack. Charging takes place via the charging cable of the mobile device, which has a USB interface. The external batteries of the popular manufacturers are therefore compatible with the popular smartphones.
