All our products are sold directly from the factory, ensuring new electronic raw materials, a short production cycle, strict control of the production process, and stable high-quality products.

2

Please note that when communicating product or packaging dimensions, there may be a slight error of approximately 2 mm due to manual measurement. Therefore, please allow enough room for reordering.

3

Generally, we provide black and white as the standard colors of the product, but other colors can also be customized. If customized colors are required, the purchase quantity must be at least 3,000 pieces.

4

Our ordinary power supplies, adapters, and chargers are usually packed in white boxes, with 50 pieces per layer and a total of 4 layers, making about 200 pieces per box. The packing quantity of each product model may vary, and details are subject to communication at the time.

5

All product quotations do not include tax and shipping costs. If the freight forwarder is in Guangdong Province, we will provide free shipping, and if the freight forwarder is in Shenzhen, we will deliver the goods to your door. All our ex-factory prices are EXW.

6

Regarding delivery, if the item is in stock when you order, we will ship it on the same day or the next day. If there is insufficient inventory or no inventory, we need to place an order for production, and delivery usually takes 7 working days. If the quantity you order is large or the purchase of certain electronic raw materials takes a long time, the production cycle may be extended to about 15-30 days, subject to communication at the time.

7

For transportation of goods, because most customers transport goods across borders, we tie the goods with bundles after packing them to ensure their safety. You also need to engage a high-quality and responsible freight forwarder to transport the goods and provide their contact information. If you choose international express logistics (DHL/UPS/FedEx/TNT), please provide your express account number and opt for cash on delivery. If you don't have a freight forwarder and need us to transport your goods, our company also has long-term high-quality freight forwarders who will help you deliver your goods safely to your home.

FAQ

 

Q: What is the difference between an adapter and a battery charger?

A: 1. Different definitions: The power adapter is an electronic appliance for small portable electronic equipment and power conversion equipment. The charger uses high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology; 
2.Different uses: the power adapter is a type of power switch, which mainly supplies power to equipment, such as audio adapters, computer adapters, and projectors. Instrument adapters, etc., while the charger is used for battery charging. It performs segmented charging according to battery capacity and charging characteristics, such as electric vehicle chargers; 
3.Different structural compositions: the power adapter has a shell, a control chip, and a printed circuit Board, capacitor, inductor, transformer, etc., while the charger is composed of a stable power supply (mainly stable working electrical appliances, power supply and sufficient current) and necessary control circuits such as voltage limiting, constant current, time limiting, etc.; 
4.Current mode Difference: The power adapter converts AC into DC output, while the charger uses a constant current and voltage limiting charging system. It can be seen from the above points that there are many differences between power adapters and chargers. It is worth noting that power adapters and chargers have different input and output powers, so they cannot be mixed at will to avoid explosion accidents;

Q: 12v2A charger charges an 80Ah battery. How long does it take to fully charge it?

A: Normally, it takes about 14 hours to charge an 80Ah battery using a 12V 2A charger. However, charging time may vary due to factors such as ambient temperature and battery status. 12V battery: According to material classification, it can be divided into: 12V lithium battery, 12V lead-acid battery, 12V nickel metal hydride nickel cadmium battery, 12V alkaline battery. 12 lithium batteries are composed of three 3.7V lithium batteries connected in series. The voltage of a single lithium battery when fully charged is 4.2V, usually also called 4V. The voltages of the series connected batteries are added together, that is: 4V/battery*3 Each battery = 12V, 3 batteries each with 2A equals 6A, 6A*14H equals 84Ah.

Q: What is overvoltage and overcurrent protection?

A: When the power supply is working, voltage and current surges may damage equipment and cause fires. A shutdown circuit designed to deal with surges can help minimize this risk. This is overvoltage and overcurrent protection.

Q: What is short circuit protection?

A: short circuit occurs when the resistance of a portion of a circuit is reduced due to misconfiguration and damage, causing current to deviate from its intended path, often resulting in circuit damage or equipment failure. Short circuit protection may include a hardwired current limit or an automatically triggered reset in response to heat.

Q: How to check the polarity of AC/DC adapter?

A: Polarity refers to the direction in which current flows, usually from positive to negative. When choosing an adapter, make sure it is compatible with the device. Polarity is an important factor to consider. If the adapter has a negative plug, it should not be connected to avoid connecting to the positive jack. Generally, the polarity of the AC/DC adapter will be displayed on the casing. We can connect the positive and negative poles according to the label on the power supply.

Q: What is the difference between AC adapter and DC adapter?

A: AC adapter refers to an adapter whose output is alternating current, while DC adapter refers to an adapter whose output is direct current. The AC adapter converts alternating current from one voltage to another voltage. The properties of the alternating current remain unchanged but the size does. The DC adapter converts alternating current into direct current. The properties of the points change and the size also changes.
