As a peripheral product of smart handheld devices, Power Bank has been rapidly popularized with the rapid development of smart phones. Its development from the barbaric growth at the beginning to the blooming of a hundred flowers, until the recent birth of the shared power pack with the upsurge of the sharing economy, shows that this product or industry is developing rapidly. I don't know whether the shared charging bank can succeed, at least I am not willing to try it for the time being. I prefer to have a more practical, more personalized, smaller and lighter power pack. Maybe there are really many people who have the same idea as me, and more distinctive power bank devices are gradually born. Today, let's take a look at one of my favorite products - iWALK pocket treasure. Thank you all here@ Computer trial And@ iWALK Provide this trial opportunity.

First, look at the outer package. The front of the package box is hollowed out in the shape of a battery, with a red background inside. In the upper left corner is a large iWALK LOGO.

There is a lot of information on the back of the packaging box. The main information includes the name, specification and model of the product. The name is Pocket Treasure Generation 3, which indicates that it has been improved twice and should be a relatively complete and mature product.

Pulling out the internal packaging box from the side, I found that the red background of the battery on the shell was actually part of a large red arrow. Under the arrow, with the product slogan, I plugged in the call.

Open the internal box to see the iWALK pocket treasure. This is a light green product, the color looks very pleasing.

The power pack is very small, almost the same size as a woman's lipstick. It is estimated that there is an 18650 battery cell inside.

The accessory box is also very exquisite, with a "skylight" on it, which should be easy to access.

The parts are very simple, with certificates, after-sales service cards and instructions.

Let's focus on the body of pocket treasure. The surface adopts small Tudian to form a frosty effect, which is not only easy to prevent slipping, but also has a good feel. There are three indicators above the middle.

From the above, we can see some nameplate information. The capacity is 3300mAh, and the input and output are 5V/1A.

One side of Pocket Bag is the charging input interface, which is Type-C version.

There is a button on the other side. Press this button to display the current power at the three indicators on the front.

Pull out the cap on the pocket bag to see the charging output interface.

Like the input interface, the charging output interface is a Type C interface. The cap can't be taken down. It has the function of preventing loss.

Press the button on the side, you can see that only one light of Pocket Treasure is on. At present, the power is low.

It's still beautiful to have a look at the cover.

Pocket Treasure products cover the current mainstream Apple, Type C and Micro USB three interfaces, each of which has four colors of white, green, pink and black.

Next, let's take a look at the charging effect of pocket treasure. The biggest feature of Pocket Treasure is that it does not need a charging cable when charging mobile phones and other devices. It can be directly inserted into the charging interface of mobile phones, eliminating the trouble of carrying a charging cable when going out.

The nominal input and output power of pocket treasure is 5W (5V/1A). The actual test current is 0.65A when charging pocket treasure, which is more than 3W. I don't know why.

When Pombo charges the mobile phone, its output power is close to the nominal 5W power.

To sum up, it is not easy for Pocket Treasure to realize the function of power bank in such a small size. In addition, it also realizes data cable free charging, so you can take one less charging cable when you go out. The workmanship is very exquisite. The cover cap of the interface is designed to prevent loss. The product is well considered in terms of interface and compatible with common interfaces in the market. In terms of shortcomings, the capacity is one of them. Of course, 3300mAh is a relatively high capacity before the 18650 cell's energy density has been improved. In addition, the nominal input and output power of Pocket Treasure is 5W, and the measured value does not reach the nominal value at the time of input. I wonder if the charging power can reach 5W only after the Pocket Treasure is completely out of power. However, the flaws do not hide the merits. Such a sophisticated power bank is really worth having.
