Something You Don’t Know About Portable Power bank------a Necessity In Life Nov 15, 2017

When our smart phones are about to run out of power, portable powerbank is often the ultimate savior, so it's important to buy a great mobile power.

If your smart phone battery have low power, and you cannot see a sock at sight, at this moment the portable powerbank can act as a savior. It can not only charge for smart phones, but also for Bluetooth devices, MP3 players and digital cameras. Of course, the price of power bank is not cheap, but we can not always measure the product by price. Expensive is not equal to good quality.

First, let's talk about its capacity: it can be calculated in milli-amps / hour (mAh) like a smart phone battery, or it can be measured in watts / hour (Wh). The battery pack with a maximum capacity of 3000 mAh can easily and perfectly charge one smart phone. A portable powerbank pack with a maximum capacity of 6000 mAh can charge for two smart phones. Power bank also comes in a variety of sizes and is suitable to be put in trousers or jacket pockets, and they generally have less weight. While the battery pack with the capacity of 10,000 mAh is heavy, it would be troublesome if you are trying to put them in trousers or jackets. They can charge for a number of mobile phones, while they have to store the power for a full week.

However, some of the manufacturer's instructions are wrong because not all electricity in the  battery packs are charged into the smart phone. Rated capacity is not equal to the actual available capacity, in the process of electricity storage, there would be part of electricity lose. For example, if a battery pack has a capacity of 5000 mAh, and now a smartphone with the capacity of 2500 mAh needs to be charged, then the battery pack can not fill two smartphones. As a reference: generally we should cut down about 30% of the power in the manufacturer's manual to get the actual power storage capacity of this portable powerbank.

In addition, the capacity does not represent everything. The current is equally important to the capacity, which was represent by amperes (A). The higher the input and output values, the faster the current will flow. As for some older and cheaper portable powerbanks, the current for smart phone chargers are typically 1A, and that for fast chargers would be as high as 2.1A. Therefore, the power bank should ensure the stability of the charging current. Important notice: To charge the tablet, the current must be sufficient, 1A is far from enough. So we prefer to buy device with current above 1.5A. The faster the current is, the easier it would protect your smart phone.

You would find many product problems not long after. I have gotten a recommendation for portable powerbank from Shenzhen Wanshuntong Science & Technology CO., Ltd. It is a phone battery and power bank manufacturer for almost 20 years. As a manufacturer having its own design patent, it has gained vast consumers around the world. We should anyway choose the ones we needs.
