The weather has been really hot recently. I recall the Samsung Galaxy Z Fold3 5G / Z Flip3 5G conference that I attended last time in MIRROR. When something went wrong, I played the camera app because of overheating every day. It’s hard for MIRROR 12 Zizhong to wear a long-sleeved suit and dance. Don’t you need to relieve heat, you need a mobile phone, you can order it? I just opened the box recently called “Black Shark Ice Sealed Refrigeration Back Holder 2 Magnetic Suction Edition”, which claims to be applicable to any mobile phone. ? After the moderator finished the trial, he found that there will be exceptions, and an unexpected thing happened. For more details, see below!
Black Shark Frozen Refrigeration Back Clip 2 Magnetic Edition Unpacking
Out of the box, there are a bunch of physical pictures, but before you look at the pictures, I will share with you directly, I will use the host iPhone 11 Pro to try it out. I will separate the advantages from the disadvantages:
| advantage | shortcoming |
| 1. The cooling effect of the phone is indeed achieved, even if there is no need for any test (I don’t have any related tools to measure the temperature), you feel cold to the touch by yourself. 2. Almost most mobile phones and even tablets are used (but there are exceptions in everything, like the Samsung Z Flip3 folding machine, you may not need it if you want to fold it), because you only need to paste it on the phone with a magnetic sticker, and then Just stick the fan down, and it’s easy to disassemble. 3. The rotation speed is 7200 rpm, and the fan sound is not too loud. 4. The price is not expensive, Fortress sells it for $359. |
1. It’s still big and old, so it’s not convenient to take it out of the street. 2. The force of magnetic attraction is stronger than that of magnetic stickers on mobile phones. Although it is easy to disassemble, once I remove them, even the magnetic stickers are removed and buried. The problem that this brings is that Chengri is throwing and idiotic, and it is easy to get rid of idiotic power. 3. Obviously there are magnetic stickers that can be bought separately, but Hong Kong is not available. If you want to buy it, you have to go to the mainland Xiaomi store to buy it, or the great Taobao can help you. 4. It does not have a built-in battery, you must pull the USB cable to use it first, it is not convenient. 5. Although it helps the phone to cool down, the fan itself still has a certain amount of heat, especially when the fan is lowered, it will feel a little hot after a while when you pick it up, so you must lower the phone when the screen is down. |
▲ The product packaging box is as shown in the picture above, all of them will have a millet flavor as soon as they are viewed.
▲ When you open it, you will see the actual fan.
▲ There is a USB C to USB C charging cable.
▲ The fan supports the MagSafe of the iPhone 12 series, but for the convenience of other mobile phones, a magnet sticker will be sent at the opportunity. And if you have multiple devices, you can buy additional magnet stickers yourself, but Hong Kong does not matter, you have to go to the mainland Xiaomi store or the great Taobao to help you.
▲ I use the iPhone 11 Pro as the host computer, which is more suitable for bare machine use. First, remove the top layer of the magnetic sticker, and then you can put the magnetic sticker on the phone.
▲ Then you can align the fan with the magnetic sticker and put it down lightly.
▲ The post is crooked, nothing has happened, and the fan will come back, and then post again. I know that the magnetic attraction force is greater than that of the magnetic stickers that fascinates my iPhone 11 Pro. In a disguised form, even the magnetic stickers can be buried, which is really unexpected. If all the downloads are attached, it’s really good to quickly post the magnetic stickers, and then there will be no fascination in the end.
▲ After several hardships, I finally got the chance to return.
▲ However, there are all disadvantages. There is no built-in battery. You must cross a fan before you can use it. That is to say, you have to hang a urine bag to stop the fan first. An inconvenient place.
▲ Because the moderator has no tools to monitor the temperature, and there is almost no app on the iPhone to check the temperature of the phone, so I found a computer app iMazing to check the temperature of the battery, and I can see that the moderator has been If you live in a mantle and use a fan, the current cell phone battery temperature is 23 degrees.
▲ After turning off the fan, I continued to live there, and saw that the temperature began to rise gradually, and after about 6 minutes, it had risen to 28.1 degrees. In the case of the mobile phone being stationary and simply staying alone, the battery temperature will start to stop when it reaches 30.5 degrees. It can be seen that the fan can cool the phone by about 7.5 degrees without doing anything. Don’t underestimate the 7.5 degree, it’s just because the phone is not working, if you call on the phone, you will see a more obvious difference.
▲ Let me turn on the fan again, and use PUBG mobile to eat chicken. After eating a chicken, you can expect about half an hour. The temperature is only 27.1 degrees. It can be seen that the heat dissipation capacity of the channel is quite strong. Unexpected, unexpected.
