The booming development of smart phones and tablet computers has also brought about the rise of another industry, namely mobile power, commonly known as "power bank". The author predicts that if no newer batteries with larger capacity are invented, the rechargeable treasure industry will continue to flourish. (It is said that graphene batteries have come into being, but it is still far from the market.) People have more and more requirements for mobile phone screens and functions. Large screens mean power consumption, while multiple functions also mean higher frequency of use. If there is a market, there will be competition. Although the Power Bank is just a simple battery cell+circuit board, its secret is very big and directly affects the use effect of the product. Of course, in addition to the internal competition, there is also the competition in the appearance design. Who has more personality, who is more practical, or small. In short, consumers are always picky. Today's experience of a power bank is a little different from the current one on the market. It is a pocket power bank produced by iWALK.

[Unpacking]

The packaging of the IVOC pocket power pack is not simple. A red battery logo can be seen on the front. The logo of iWALK is on the upper left corner and the corresponding charging port logo is on the upper right corner. At present, there are three versions of this power pack, namely, the Apple specific Lighting interface, the Android specific Micro interface and the Type-c interface. This time, I got the Apple version. On the back is the detailed information and production information of the product. After all, the market is uneven and the information signs are complete, which can also make users feel more confident in purchasing.

Open the box. In fact, the box is quite creative. When you open it, you can see the words "plug in the call" followed by an arrow direction, which clearly highlights the characteristics of the product. That is, this power pack is different from ordinary power packs. It does not need a charging line, but is a straight plug type. The pocket treasure on hand is a black version. According to the official website, there are four colors available, namely white, green and fans.

The configuration of Pocket Treasure is very simple. In addition to the certificate, manual and warranty card, and of course the product itself, there is no additional charging line. For the manufacturer, it may be enough that you already have the original mobile phone charging cable, but the more this cable is, the better. It would be better if you could add one more.

The pocket treasure is probably the smallest among the used charging treasure. It is only two fingers wide and can be easily held by one hand. The whole design is a little similar to a lady's purse, and the appearance is similar to a mesh woven design. You can see the indicator light of the remaining power. On the upper part, you can clearly see the capacity of the product, 3300mAh, which is almost the same as the lithium battery of a mobile phone on the market.

The difference between this pocket treasure and ordinary charging treasure is that it does not need to connect the charging cable, but directly charges the mobile phone or tablet. There is a cover at the charging port. If you peel it off, you can see the corresponding plug inside. However, to charge the pocket treasure, you need to use the original charging cable to charge it on the side.

I have used many different types of power packs. Of course, each has its own use. The large one has sufficient power. However, it is bulky. If it is not a long-term trip, commuting or something, the pocket bag is small and easy to carry. And the charging can be controlled through the switch.

I took the iPhone SE and tested it. It was found that it was very tight after being plugged in and charged. It was difficult to fall down even if I shook it a few times. The key is that even if you have pocket treasure in your pocket, you can also chat, brush Weibo and even play Glory of the King.

Try the small one. Try the large one. The iPad Mini can also be charged. The charging speed is also fast. If it is not for mobile phone or iPad games or use, you can obviously feel the recharging speed when the screen is off. But after all, the input voltage is 5v/1.5A, and the output voltage is 5v/1.5A. If you want to fast charge, you have to think a lot.

The pocket treasure is small and portable. Even if it is put in the pants pocket, it will not take up more space and weigh more. The power of about 3300mAh cannot be said to be very large. After all, the volume is there, and 1.5 times of charging is enough, and the charging speed is not fast. The most suitable feature is that it is usually used as a supplementary power supply to commute to and from work. Usually, it seems that there are too many kinds of equipment, and it is almost "light" to go out, but smart phones need to always maintain the power at about 50%, Otherwise, I always think that it will shut down at any time, and the pocket treasure must be the best choice.
