Application:
As we know, for iPhone XS and above models, when a third-party battery or a genuine replacement battery is replaced by a third-party repair shop that isn't one of Apple's authorized partners, the battery health menu will show a warning about being unable to verify this iPhone has a genuine iPhone battery. The solution for this kind issue is to swap the original battery protection board to the new battery. This spot welder can be used to solder the battery protection board to solve this problem.

Instructions:
1. Power on/off.
Press and hold the power button for two seconds in the shutdown state, the light goes on and the device turns on.

Automatic output: The spot welding pen is automatically detected and outputs once when both welding pens are detected to have touched the metal.

Note:
1. In cold weather conditions, battery performance may be reduced, warm up more than a dozen solder joints, and can restore performance. It is best to use in a warm room, charging to be timely, low-charge shutdown, can be recharged and reawakened.
2. If placed for a long time, the device needs to be fully charged and charged every two months. If the device has entered deep sleep mode, the voltage is reduced to no power, please contact customer service to learn how to wake up.

⭐⭐⭐⭐⭐ "Excellent value for money and very efficient charging!" I bought this pack of 2 MagSafe chargers from TNDAJI and I couldn't be more satisfied. I love that it includes USB-C to USB-A adapters. This allows you to use them with both modern and traditional charging cubes, which is a great detail. The magnet adheres perfectly to my iPhone and does not release easily, allowing me to continue using the phone while charging. The blue light ring gives it a modern and elegant touch, in addition to helping to locate the charger easily in the dark without being annoying. The 15W works wonderfully. Charge my AirPods and phone quite fast for a wireless connection, and I haven't noticed excessive heating. For the price of an original one, you get two high-quality chargers with their adapters. Super recommended to have one in the office and another on the bedside table!"

Great MagSafe charger set.
Great MagSafe charger set. The magnetic alignment is strong and keeps my iPhone securely in place without slipping. It charges quickly as described, especially with a proper PD adapter, and both my iPhone and AirPods work perfectly with it. I also like the soft LED light that doesn’t disturb sleep and the fact that it stays cool and feels safe during use. Having two chargers in the pack is very convenient. Overall, excellent value and very reliable—definitely 5 stars.

Great Value and Convenient Charging Set
I’m really happy with this MagSafe Charger 2 Pack! The chargers are lightweight, easy to use, and connect perfectly to my phone with a strong magnetic hold. Charging is fast and reliable, and having two chargers is super convenient for home and travel. The cables feel durable and the overall quality is great for the price. Definitely a good purchase if you want an affordable alternative to expensive brand-name chargers. Highly recommend!

Not fast but steady
Not a fast charger but that’s not what I wanted - no over hearing experienced and using for overnight is no issue. With proper power brick it is very serviceable for topping off my 17pro and getting 2 for so cheap makes it a win for me
