Once upon a time, the functions of mobile phones were only calls and text messages, and it was a common phenomenon to recharge every two days. However, with the development of digital technology, the functions of mobile phones became more and more, and people's demand for mobile phones continued to increase. More and more mobile phone products could not last for a day under the intensive use of users, so mobile power was born.

At the beginning, most of the mobile power supplies were large 3000mAh products. Later, the capacity became larger and larger, and the products became smaller and safer. Now 10000mAh mobile power is widely available, and people can also see everywhere holding a mobile phone and a huge mobile power supply, and even a 1m long data cable is connected in the middle. This user experience is very bad. As a result, there are products with charging connectors integrated into the power bank, such as Apple's Smart Battery Case, which sells for up to 848 yuan, and the battery behind it is very abrupt. However, it is clear that the manufacturer thinks Apple's is good, so it also learns from Apple and launches a similar clip on mobile power protection case, which is relatively cheap, but there are still problems specific to special computers, Cannot share with other devices.

Obviously, if the interface is to be integrated into the mobile power supply, either the mobile phone shell of the clip on mobile power supply is removed and made into a normal shape, or there is a lump of charging treasure right below the mobile phone interface. This time we will discuss whether the following form of mobile power supply is practical - take iWALK pocket treasure as an example.

The outer package of the iWALK pocket treasure is very simple, with only one battery logo. The logo of the big Made For iPhone also shows its noble authentication identity. After opening the drawer type package, you will see that the battery logo becomes an arrow with the text "Insert the incoming call". The interface information is written on the side, and the details are on the back.

The overall accessories are very simple, just the main body, instructions and warranty card. Of course, you can't ask it to give away the lightning data cable of mfi.

The shape of the iWALK pocket bag is like a cylindrical battery, and its external material should be plastic. However, metal materials should not be used for such products that are directly connected to the mobile phone through the interface, otherwise the product quality will be too high and the interface will not be able to carry this weight.

Its left side is the Lightning interface, and the right side is the power key. The basic information is marked on the top of the fuselage: the capacity is 3300mAh, the input and output are 5V=1.5A, the rated capacity is 2050 mAh, and the conversion rate is>62%. I felt that the information was very honest and told the user. The right side is the wake-up key.

IWALK pocketbook owns M F. I. (Made For iPhone) certification, so we are not afraid of Boom. There are three LED indicators on the front, representing 1%~50%, 51%~90% and 91%~100% respectively. The upper left corner is the sign of iWALK

It's great to turn it into Every Day Carry. The iWALK Pocket Bag weighs only 75g. After it is inserted into the iPhone 7, the overall weight reaches 213g, 25g heavier than the iPhone 7 Plus, and the weight is acceptable. At least the smart battery case with specific capacity of 1877mAh and weight of 100g is fine.

You can even easily put the iWALK pocket bag into your pocket, instead of holding a power pack, a wallet, an umbrella and a backpack. The mobile phone is out of power and can be charged directly from the pocket, which reduces the trouble of purchasing the Lightning data cable and the carrying of things. It is very convenient.

At the same time, the iWALK is equipped with the lighting interface, which can directly plug the iWALK into the mobile phone while using the original iPhone charger to charge the iWALK, so that you can harvest two fully charged devices the next morning.

However, the size of iWALK may not be suitable for iPhone 5/5s/5c/SE. It should have better sustainability on 4.7 inch iPhone and 5.5 inch iPhone.

In general, this customized product for iPhone is worth buying for the following reasons:

1. It is very convenient to carry, and the appearance is exquisite

2. Directly equipped with lighting interface, no need to purchase additional data cable

3. 3300mAh capacity is enough for more than one full charge of 4.7 inch iPhone

Of course, its capacity, appearance and details can be better, and we look forward to new products.
