According to criminal psychology analysis, generally speaking, it will hide in two places.
One is the common area, because the most dangerous place is the safest place. And even if the things that were taken are discovered, it is not easy to locate the specific person and time, which is conducive to the perpetrator to clear the suspicion.
The other is the most private place, such as the bottom of his cabinet, inside the locked suitcase, so that you are not easy to find, because once you find him, it will inevitably have nothing to do with him.
Good luck finding it soon.

The workmanship and quality are not bad. As for other standard 20,000 mAh and other power banks, as long as they are seventy or eighty, they are copycats, which are prone to problems. So, I personally still hope that you go to a certain treasure to take a look at those brands.

This one is different according to the capacity and style, the price is also different, to give you some advice, you see what kind of suitable one to buy.
What capacity is it appropriate to choose a power bank?
With the intellectualization and large-screen of mobile phones and tablets, the demand for power is increasing, and ordinary batteries can no longer meet the needs of normal life. The capacity of the power bank is also getting larger and larger, and now there are more 5000,,6600,7500,8000,10000,10400,11000,12000,13000,20000,22000,26000... There are many merchants who are claiming that their mobile charging treasure has a large capacity of 30,000,5000,If you take a look, the most popular long-tail word is 20,000,30,000,50,000 large-capacity mobile charging treasure, and **only a few dozen yuan, for such you must not buy, don't be greedy for cheap, a penny is worth the goods, merchants will not do loss-making transactions; As for why such a large capacity is only a few dozen yuan, I have introduced it in detail in other articles, let's take a look at how much capacity the charging treasure is the most suitable?
Mobile power bank capacity selection.
A large capacity is not necessarily suitable.
If the capacity is too large, the time to charge the power bank will definitely increase, and if it is not used up for a long time, the power will be lost; If you don't use it for a long time, too much power will damage the power bank, in addition, the larger the capacity, the larger the virtual standard, so don't choose the largest, choose the most suitable.
How to choose the size of the capacity?
1. Choose according to the number of charges
Let's look at a formula: the number of charges = the capacity of the power bank x the effective rate of conversion of the capacity of the mobile phone battery.
If you don't go out often and often have a rechargeable power supply, it is recommended to choose 2-3 times; Choose the appropriate one with a small capacity; If you go out often, you need to choose about 4-5 times of charging, and choose the one with a larger capacity;
Second, choose according to the battery capacity of the mobile phone.
Generally, the capacity of the power bank is several times or slightly larger than the charging capacity of the mobile phone, or it can be appropriately larger, and it can be selected according to the demand;
3. Choose according to the ease of carrying.
The mobile charging treasure is generally selected in 5000-10000 capacity is more appropriate, and the larger one is more expensive, the weight and volume are also large, and it is not very convenient to carry.
Don't use power banks! The power bank is to forcibly charge the mobile phone, which is not good for the mobile phone battery and will shorten the battery life.
