This article will combine the hot content of the entire network in the past 10 days to provide you with detailed disassembly steps and precautions, as well as relevant data comparisons.
1. Preparation work before disassembly
Before disassembling the LeTV charging head, you need to prepare the following tools and materials:
| Tools/Materials | Purpose |
|---|---|
| Screwdriver (slotted and Phillips) | Remove housing screws |
| Spry bar or plastic card | Separate shell |
| Multimeter | Detect whether the circuit is live |
| Insulating tape | Protect exposed circuits |
2. Disassembly steps
1.Power outage check: Make sure the charging head has been unplugged from the power socket, and use a multimeter to check that there is no residual current.
2.Remove the casing: LeTV charging heads usually adopt a snap-on design. Use a spudger or plastic card to gently pry it open along the edge. Be careful not to use excessive force to avoid damaging internal components.
3.Separate the internal circuit board: With the case open, you'll see the circuit board inside. Most LeTV charging heads use screws to secure the circuit board. Use a screwdriver to remove the screws to remove the circuit board.
4.Check components: After the disassembly is completed, you can check whether the capacitors, resistors and other components on the circuit board are damaged or burned.
3. Comparison of popular models
The following are the LeTV charging head models and their features that have been discussed a lot on the Internet in the past 10 days:
| Model | Power | Difficulty of disassembly | FAQ |
|---|---|---|---|
| LeTV QC3.0 | 18W | medium | The buckle is tight and requires patience to pry open. |
| LeTV PD fast charge | 30W | higher | The internal structure is complex and requires professional tools |
| LeTV USB-C | 15W | simple | Fixed with screws, easy to disassemble |
4. Precautions
1.Safety first: During the disassembly process, make sure the device is completely powered off to avoid the risk of electric shock.
