A dead phone on the going journey may ruin everything in your schedule if you ever expect a pleasant and leisurely journey. Before things go awkward and frustrating, you still deserve to use a portable power bank to avoid such a crappy day. The best portable power banks for travel, in the first place, need to be portable in size, light in weight and powerful in output rating, so that these power banks can help charge your cellphone up easily. Putting a useful power bank in your handbag or pocket is really what you should do before your travel because it can keep your phone battery going no matter how many high drain apps are killing your battery in there.
A pocket-friendly power bank should be perfect. An ideal size should be almost the same as a frequently-seen smartphone, like a Samsung C7, or slightly bigger. It's always Okay to be somewhat thicker but no one expects it to be too heavy. A pocket-sized power bank is easy to store in handbag, backpack, even your pocket and a palm-sized one makes itself most portable to carry around. You would never expect something bigger than 6 inches for the length, 3 inches for the width and 1 inch for the thickness.
Of course, a powerful power bank with a quality high output battery inside has to be a little heavy holding in hand. Yet a compact size in the design with the inside battery well engineered will still make it light and handy. The ideal weight should be around 10 ounces.
2 USB ports are becoming more and more popular so 2 ports is a must in output design. The output amperage will decide how quickly a power bank can fully charge your cellphone. So, if you can get something like a 5V 3A output power bank on the market, it’s a great choice.
Speaking of prices, we need to evaluate something by defining whether or not it’s a worthwhile investment. The value of a power bank mainly depends on the quality of the battery inside because that will decide how long it will last fundamentally. Generally a power bank with a capacity 10,000mAh is worth $20 around.
