At the Grand Palace in Paris, HUAWEI officially announced the new generation of HUAWEI P20 series two months ago. The Huawei P series have always paid great importance to photographing, and this time Huawei P20 updated five new photography features.

Currently in all the Android smartphone brands, Huawei may be doing the best with digital zoom. At the same time, HUAWEI P20 has the three new advantages of its battery: 3400mAh large capacity, intelligent power-saving technology, and super-charging. When using the P20 original charger to charge the phone, the output voltage and current (charging model) is about 4.5V/ 5A.

Although HUAWEI P20 has smart energy-saving features and super-charge technology, there is no doubt a portable charger is essential for us who lead a rapid pace of life. When you want to buy a portable charger for HUAWEI P20, you may not know that the voltage and current “4.5V/ 5A” mentioned above matters. Why is it necessary to consider it? Read to understand the following questions first.

Q: Is a power bank universal? That is to say, could I use one whose model is not compatible with my mobile phone battery?

A: Certainly not. If the output power of the power bank exceeds your battery's acceptable range, although the battery can also be charged, the battery life will be damaged greatly, and even battery explosion could be caused.

Specifically, a power bank is equivalent to a power supply, which has its own output voltage and current. The power bank voltage is preferably matched with the output voltage of the cell phone charger. Distinct output power differs the length of charging. In general, the lower the power is, the slower the charging speed.

Q: Does a power bank affect the life of the battery, especially for phones which can be super charged like HUAWEI P20?

A: You may have heard this: do not use power bank regularly, otherwise it may affect the life of the mobile phone. If you can use the official standard charger, then use a power bank as little as possible.  In fact, many experts have said as to what affects mobile phone battery life most, "phone usage while charging" is the biggest culprit.

A bank power is smart. We all know that nowadays mobile phones, power banks and chargers are protected in various ways during the charging process: over-current protection, over-heat protection, over-voltage protection, etc. A power bank is not only the collection of batteries; the tiny chips can protect the circuits.

Which power bank that is compatible with HUAWEI P20?

To choose a power bank for HUAWEI P20, we need to consider that the output voltage and current of its official charger is about 4.5V/ 5A. Choosing a power bank whose model matches the mobile phone bears repeating, here is a recommendation.

Zenture A3TC USB-C    ——strikes the perfect balance between durability and style.

When a power bank and a mobile phone both support fast charging function, then the super charging can be achieved, otherwise it can only do the normal power bank charging speed. However, speeds as fast as quick charge can also be achieved by the fast and future-proof charging technology of Zendure A3TC. It can charge compatible devices at the highest speed with 5V 3A output. General power banks have a relatively large range of charging in order to adapt to most mobile phones. For example, HUAWEI P20 battery is within this range (the output voltage of Zendure A3TC could be 4.5V), which means it can be used.

With Zendure A3TC it you get a companion for your journeys on the road and it has the following distinctive features, which helps decrease your worries about battery life and enjoy the convenience produced by technology.

  1. Durability: Zendure batteries originated from one of the most successful external battery projects on Kickstarter. A-series batteries can survive being run over by a sedan. Crush-proof composite material, dual-injection molding and a shock-absorbing central belt make Zendure portable chargers some of the most durable external batteries available. In addition, this power bank can maintain up to 95% capacity after six months in standby (when USB disconnected), which is a great feature for your emergency backup.
  2. Lightweight & style: thanks to the use of top quality components, A3TC is one of the most compact and lightweight, yet high-power batteries on the market. Yet with 10,000 mAh capacity, this little thing can easily extend your phone usage 3-4 times. Stylish silver, black or red are available.

The selection of a genuine bank power is significant. If you choose a cheap, low-quality power bank, it may not reach the charging standard of the mobile phone battery in use. This would affect the charging nd even harms your mobile phone! And again, make sure the model of the power bank matches your mobile phone next time when you’re purchasing one.
