Also i have some tips for you:

If you have the habit of carrying too many devices while on travel, a high capacity power bank may be onto you; Of course, a low capacity portable charger would also be sufficient. Here are a few tips based on the major points:

Capacity: while choosing a right power bank, capacity is the foremost point you should consider. Power bank capacity refers to how much power is inside a power bank battery. Normally, it is measured in mAh or milliamps per hour. Noted that when charging a smart phone or tablet through a power bank, here will cause some power loss. So the real capacity of a power bank is about 70-75 percent of the battery capacity listed on the power bank. For example, a power bank with battery capacity at 10000mAh, while its real capacity may be in the range 7000mAh to 7500mAh. And this is for quality battery. If for downgraded battery, the loss of power is even more.

To meet ever-growing charging needs, many higher mAh units are available on the market now. But, keep your own usage in mind while wanna buy a power bank.

Connectors (or output ports): the number of connectors and the type of connectors matter. Regarding the type of connectors, Smart Charge and Quick Charge boost.

If you always forget to take along a charging cable, it would be more advisable to go for a power bank with built-in cable.

Smart Charge Features

Price: power banks with higher capacity while with a substantially lower price may not be genuine (Price of Best 20000mAh Power Bank). Pay attention, please. Most of them use refurbished battery which may not last long.
