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.
Press and hold the power button for two seconds in the power-on state, the light goes off and the device shuts down.

Automatic output: The spot welding pen is automatically detected and outputs once when both welding pens are detected to have touched the metal.
Manual mode: press manual spot welding button for one second, the spot welding pen will be output once.

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.

Convenient set with charging stand and light
Color: 2-Speed Silver, Size: Rechargeable
Recommend for anyone who cooks and wants fresh seasoning with less hassle. The built-in light on the bottom was a pleasant surprise and ends up being genuinely useful. It helps you see exactly where the seasoning is going and how much you’re dispensing, especially when you’re cooking in the evening or working over darker foods. That small detail makes the set feel more practical than a basic grinder.

Great Little Gadget
Color: C-Black, Size: Model C Rechargeable
What a fun and easy to use gadget! I use it to foam Zero Sugar Coffeemate creamer for my iced coffee and it works perfectly. I thought the on/off button was on the top but it's on the side. I was concerned that I would unintentionally bump it but I don't. Easy to use, easy to clean and price is reasonable.

Good speed
Color: C-Black, Size: Model C Rechargeable
Love the rechargeable feature, works great as a frother, however, I have to get use to the on/off feature instead of the press to froth like the older unit.
