Where can I get my external battery repaired if it breaks?

There are many circuits inside the power bank. Often the reason electronic products break down is because they are not properly maintained. Bumps and shocks will damage the internal parts of the power bank. If one thing is broken, the entire device will become unusable, and repairing a power bank is not a simple repair of a device. Just like damage inside a cell phone, many unprofessional people cannot repair it. so when you buy electronic products, you must buy good service. After-sales service is very important, at least good after-sales service will not make your equipment unable to find a place to repair it.

If the power bank is not used for a long time, it can be repaired.

The main cost of a power bank is the nbattery core (lithium battery). If the power bank with good power is broken, it still has repair value.

It is best to contact the original purchaser for repair issues. If that doesn't work for you, you can go to a local cell phone repair shop or find small online stores that sell power bank sets.

There is no usual brand, so I have to ask a cell phone repairer to check it. If the circuit solder joints fall off, it's very simple. If the battery core is broken or circuit board. the components are damaged, it will be more troublesome. So if you usually buy branded products, after-sales service will be somewhat guaranteed.

What material is the contact point of the fast charging port of the new energy vehicle made of?

If you want to adda charging port to the DIY flashlight for direct charging, this process involves circuit modification and soldering operations, which require some time knowledge and skills in electronic technology. Here are the general steps for your reference:

1. Prepare tools and materials: You will need the following tools and materials:

- Battery holder or battery holder

- Charging port

- Soldering iron

- Solder

- Wire

- Heat shrink tubing (optional)

- Insulating tape (optional)

- If an alternative battery is present, a safety circuit protection module may be required.

2. Open the flashlight: Depending on the model and construction of your flashlight, find a way to remove the flashlight shell and open the flashlight to expose the battery.

3. Wiring: Determine where to install the tank portge and use a soldering iron to connect the charging port to the positive and negative terminals of the battery. Typically, the positive terminal is connected to the center contact inside the flashlight and the negative terminal is connected to the outer metal container.

4. Attach the charging port: Attach the charging port to the battery holder or mount, making sure it is securely seated inside the flashlight.

5. Soldering and insulation: Use solder to connect the wires to the charging port, and use heat shrink tubing or insulating tape to protect the soldered part. Make sure the solder is tight and there are no shorts between the wires.

6. Return the flashlight to its original position: Install the battery holder or bracket with charging port and return the flashlight to its original position.

Please note that this is a compareason Complex DIY operations may involve differences in flashlight design and circuit structure. If you are unsure of your abilities, seek professional help. Additionally, before performing any DIY operations, be sure to disconnect the battery and confirm that your operations will not damage the flashlight or cause dangerous situations such as electric shock.

The contact point of the fast charging port of the new energy vehicle is made ofcopper alloy. The pins are not entirely plastic and the root of the charging port may be covered in plastic. Yes, the charger plug is a low voltage current insulator. In theory, fast charging of new energy vehicles will damage battery life to a certain extent, but this damage is relative to slow charging. If the user pIf you clearly feel that the battery is not working after too much fast charging time, it means there is a problem with the car's fast charging settings.

The difference between fast charging and slow charging

New energy vehicle batteries currently on the market are mainly lithium iron phosphate batteries and ternary lithium batteries, both of which are lithium batteries. The process of charging and discharging lithium batteries is the process by which lithium ions migrate through the electrolyte to the positive and negative electrodes. Regardless of charging or discharging, lithium ions move in one direction, so lithium ions can only receive or produce direct current. Slow charging current conversion depends on the rectifier installed in the car, but as the rectifier also generates heat lWhen it works, it will cause heat dissipation problems.

If the battery cells of two cars are identical and can guarantee a lifespan of 1,500 cycles in slow charging, one of the cars can set the fast charging mode to charge 80% in 15 minutes, but fast charging mode Charging life is only 500 weeks; while another car is set to charge to 80% in 30 minutes, and the fast charging lifespan may still be 1,200 weeks, then the car in front should use fast charging as little as possible; as possible, and the fast charging of the car behind even I don't feel the difference even if I use it regularly.
