High temperatures may cause it to explode or spontaneously combust. Generally, power banks contain lithium batteries, which are highly prone to explosion when exposed to sunlight in a confined car environment where temperatures can exceed 80 degrees Celsius. Therefore, it is best not to leave a power bank in the car, especially for extended periods, as it poses significant safety risks. Below is relevant information about power banks: 1. Power Bank Introduction: A power bank is a device that can directly charge mobile devices and has its own energy storage unit. The main types available in the market are multifunctional power banks, most of which come with standard USB outputs. They can generally meet the needs of various digital products such as mobile phones, MP3 players, MP4 players, PDAs, PSPs, Bluetooth headsets, and digital cameras. Essentially, a power bank is a convenient, portable, high-capacity power source. It is a portable device that integrates energy storage, voltage boosting, and charging management. 2. Power Bank Functions: A power bank has its own charging plug that can directly charge mobile devices via an AC power source while also serving as an energy storage device. It is equivalent to a hybrid of a charger and a backup battery. Compared to a backup power source, it simplifies the need for a charging plug. Unlike a charger, it has its own energy storage unit, providing a backup power source for digital products when there is no direct power supply or when traveling.

How Many Centimeters Do Wheels with -12 Offset Extend Outward?

Wheels with a -12 offset extend the tires outward by 1.2 centimeters. Below is an extended introduction: Introduction: The wheel hub is the rotating part of the wheel that connects the tire's inner rim to the wheel core via spokes, i.e., the metal part that supports the center of the tire and mounts onto the axle. It is also known as the rim, steel ring, wheel, or tire bell. Wheel hubs come in many types based on diameter, width, forming method, and material. Types of Wheel Hubs: The wheel hub is also called the wheel rim. Depending on the characteristics and requirements of different vehicle models, the surface treatment processes for wheel hubs vary, generally categorized into painting and electroplating. For ordinary vehicles, wheel appearance is less of a consideration, with good heat dissipation being a basic requirement. The process typically involves painting—spraying followed by baking—which is cost-effective, aesthetically pleasing, and long-lasting. Even when the vehicle is scrapped, the wheel's color remains unchanged.

How many hours should an overhauled engine idle for break-in?

An overhauled engine requires approximately one hour of idling for break-in. Below are precautions for vehicle break-in after an overhaul: RPM: Engine speed should not be excessively high; it is recommended not to exceed 3,000 RPM. Warm-up: It is advisable to warm up the engine for a period (typically 3-5 minutes) when starting a cold engine, and normal driving can commence once the coolant temperature reaches the normal range. Avoid sudden acceleration or braking: Long-distance driving is not recommended immediately after an overhaul. Avoid sudden acceleration or braking as it can cause significant impact damage to the engine, hinder the break-in of internal components, and result in excessive clearance between parts, thereby affecting long-term service life. Maintain steady speed and shift gears frequently: Try to maintain a steady speed, preferably between 50-80 km/h. Avoid prolonged low-speed driving and shift gears frequently to ensure even break-in of all gears.

Can someone other than the car owner handle vehicle inspection in another city?

Vehicle inspection in another city can be handled by someone other than the car owner. Here are the relevant details: Power of attorney is required: The car owner needs to obtain a Notice of Entrusted Inspection from the original vehicle registration authority, authorizing another city's vehicle management office to conduct the annual inspection of the vehicle. When applying for the power of attorney for cross-city vehicle inspection, the car owner does not necessarily have to go in person. Relatives or friends can handle it at the original registration location and then mail it back to the inspection city. Important notes: It should be noted that the power of attorney for vehicle annual inspection must be obtained from the original registration authority. Without this power of attorney, vehicles registered in other locations cannot undergo normal annual inspections elsewhere. Currently, the only documents required for vehicle inspection in another city are the original vehicle license, copy of compulsory insurance policy, and a photocopy of ID card.

What are the effects of a broken rear trailing arm in a car?

If the rear trailing arm of a car is broken, it can have the following effects: 1. It can cause a decrease in body stability and produce various noises. 2. The handling and comfort will decrease, and the safety factor may be reduced. 3. The alignment parameters will be inaccurate, leading to drifting. 4. Other components may experience abnormal wear or damage, and the steering function may even fail. The functions of the rear trailing arm are as follows: 1. The rear trailing arm is a mechanical tool, referring to the multi-link suspension. The multi-link suspension uses different link configurations to automatically adjust the camber angle, toe angle, and provide the rear wheels with a certain steering angle when the suspension is compressed. 2. The rear trailing arm is a crucial component of the chassis suspension system, elastically connecting the body and the wheels. When the car is in motion, it can mitigate the impact forces from the road surface, ensuring passenger comfort. 3. It also improves the handling of the car tires, providing the driver with a better driving experience.
