Imagine what it would be like to travel a long distance without a mobile phone? I am afraid that many people would rather go home without hesitation and get their mobile phones. The most feared thing about traveling and business trips is that the mobile phone is out of power, so many people will have 1-2 super-capacity power banks in their suitcases, the purpose is to keep them online at all times. Today we introduce this magical power bank, not only magical on the new material "graphene", the editor is concerned about its fast charging performance. This graphene power bank with a capacity of 5400mAh can be fully charged in 15 minutes, while ordinary power banks need 3-6 hours.

    As we all know, graphene is a new type of nanomaterial with the best conductivity and heat dissipation performance known in the world. And this power bank, which uses graphene high-rate polymer batteries, is bound to be a bit higher in charge and discharge speed and battery performance than ordinary power banks.

    The advantage of owning this power bank is that I finally no longer worry about it. The next day, because I did not prepare enough energy for the power bank in advance, I was looking for a charging device in a strange place on the street. This power bank can be charged for 5 minutes, and it can talk 6 Hours, 3 hours of listening to music, 1 hour of video, 40 minutes of games.

    Compared with fast charging, it is not inferior to ordinary mobile power in fast release performance. Although mobile phone batteries still can't get beyond the limitation of small capacity, many mobile phone manufacturers are still full of justice in charging fast.

    Of course, the fast charging and discharging speed means that the current carried by the power bank will also increase, and the safety factor of the power bank will be lower if it is handled improperly. This power bank is still very good in terms of battery overcharge and overdischarge protection, short circuit protection, overvoltage and undervoltage protection, and overcurrent protection. At least there is no need to worry about a "time bomb" around you.
