With the popularity of large screen mobile phones, and for more beautiful integrated design, more and more mobile phones choose the design of non replaceable batteries. In the case of limited battery power, more and more people choose to purchase mobile power supplies as backup power supplies, which can charge mobile phones and tablets anytime and anywhere. Before the revolutionary change of battery technology, the battery capacity and volume of mobile power supply were irreconcilable, which also gave manufacturers different choices: some chose to use large "bricks" for long life; Some choose small "lighter" for portability. Recently I received Love to play computer games The third-generation pocket treasure mobile power supply sent by us has won many people's favor by virtue of its compact and delicate shape and convenient portability. Today, the author will introduce this lovely pocket treasure to you.

The outer package of the iWALK pocket treasure is mainly white, and there is a hollow battery shape in the middle of the front. I thought it was just to show the color of the inner package, but immediately the author realized the error.

With the push and pull of the inner package, the battery color will change from red to white, which is similar to the charging effect of the battery. This is really a creative design, just like its slogan, "plug in the call".

The back of the package is the product information and function introduction of Pocket Treasure, and the lower part is the manufacturer information introduction, which is set in a more conventional way.

The product name on the side is "pocket treasure (3rd generation)".

There are three connector versions of Pocket Bag, namely Apple Lightning, Android Micro USB and Type-C connectors, which meet all smart phones on the market. Since the main machine of the author is the Micro USB interface Android machine, this time I got the Micro USB version of Pocket Treasure.

When the outer package is removed, it can be seen that the inner package is a large red arrow, which is matched with the charging logo of the lightning pack and the slogan of "plug in the call", indicating that this is a portable power bank.

The package of iWALK pocket treasure is small, and the pocket treasure inside is correspondingly smaller. Since Pocket Bag is charged in line, it is not equipped with a charging cable.

The unpacking list of iWALK pocketbook: one pocketbook, one manual, one after-sales guarantee card and one certificate of conformity. There are no other accessories, which is so simple.

The oval cylinder shape of the iWALK pocket treasure is quite personalized, which not only maintains a high face value, but also guarantees the battery capacity. The pocket treasure has four colors: black, white, pink and green, each with its own characteristics: black is quiet, white is elegant, pink is lovely, and green is lively. The green version received by the author, with dot pattern on the surface, has both decorative and anti-skid functions, and feels good. There is a LOGO of "iWALK" in the upper left corner.

There are three holes in the middle, and the LED indicator light in the hole is used to indicate the power of the pocket treasure. The display effect is very intuitive, so that users can see it at a glance.

Compared with the Meizu MX3 mobile phone, the iWALK pocket treasure is still small, and it is not a problem to carry or charge.

The upper part of the pocket bag has a flat and prominent shape, which is also to make the phone fit more closely with the phone when it is plugged in for charging. In the middle is Micro USB interface with protective sleeve. On both sides of the plug are printed the relevant information of pocket treasure.

The Micro USB interface is protected by a leather sleeve, which cannot be removed and can only be opened to one side. This will cause a problem. The writer looks down.

As the author uses Meizu mobile phones, the Micro USB interface is designed with the flat mouth upward, which leads to the case that the protective sleeve blocks the home key of the mobile phone when using Pocket Treasure to charge the mobile phone, affecting the operation. The charging port of Huawei's tablet is located at the lower right corner, which does not conflict with the key, so it has no impact on the operation. However, since the Lightning interface and Type-C interface can be charged both in front and back, no such phenomenon occurs. It is hoped that Pocket Treasure can find more perfect interface protection measures for micro USB interface power packs.

Demonstrate the influence of the interface protective sleeve on the mobile phone operation through the dynamic diagram.

On the other side of the pocket treasure is a series of equipment numbers, which are unknown at present. Why must they be printed on the back, so as not to be dull?

On the left and right sides of the pocket treasure are the Micro USB charging socket and the charging switch of the charging treasure. Since the pocket treasure can automatically recognize the insertion state and automatically charge, the charging switch only has the function of turning off the charging function, while the user can turn off the charging operation by pulling out the charging treasure directly, so the switch function is slightly weak.

Apart from the influence of pocket treasure on the home key, thanks to the compact body, pocket treasure has no significant impact on the weight or ease of use of the mobile phone, and it is easy to make calls and play games.

Due to its small size, the iWALK pocketbook has a battery capacity of 3300mAh, input and output power of 5V/1.5A, and a charge conversion rate of 62%. The author uses Meilan note3 for charging experience. The maximum input power of Meilan note3 supports 5V/2A, so it can support the charging of pocket treasure. The actual charging speed is acceptable. However, because Meilan note3 is a mobile phone with a large 4100mAh battery, the power of Meilan note3 cannot be fully charged once using Pocket Treasure, so Pocket Treasure can only be used as an emergency charge. However, the main feature of Pocket Treasure is small and easy to carry, plug and play, and it is forgivable to use less power.

In the process of charging Pok Pao, the author used Huawei's 5V/2A charging head and data line to charge Pok Pao. The measured input voltage was stable at about 5.15V, while the input current was only 1.13A, and the power was only about 5.82W. There was still a difference between the official 5V/1.5, and the total power of 7.5W. The author changed other charging heads and measured the data line, and the data was still similar, In the end, it took nearly two and a half hours for Pombo to rush from 0 to 100%, which is also far from the expected time. It is hoped that the official can improve the charging technology in the next step to make it worthy of its name.

In general, the iWALK pocket treasure has been positioned from the beginning as a delicate and portable rechargeable treasure that can be easily put into the pocket. At the same time, due to the design of direct plug-in charging, no additional data cable is required. As well as its rounded shape and ingenious color matching, it stands out from the stereotyped "brick" charging treasure and is a charging artifact worth having.
