How to purchase a suitable Charger?

Virtually all electronic devices, form a mobile phone, a tablet to a Laptop, need to be charged. With latest phone, its charger will no longer be included in every box, as phone manufacturers move to reduce package waste. Chargers, the important part of electronic devices, have become an increasingly important product in daily life.

There are a variety of chargers on the market. Just like you, we’ve experienced long charging time, big size, hot, spotty charger. How to purchase a suitable charger? Here, we explain to you three important things to keep in mind when buying a charger.

1. Safety

We tested a range of unqualified chargers and found that 98% of them had the potential to cause a lethal electric shock or start a fire.

Plug the charger into a socket without connect any electronic devices

If the charger does not easily plug into a socket, overheating, arcing and mechanical damage can occur to both the socket and the charger, which can be dangerous.

Check for the certificates mark.

The charger must comply with national standards. Such as: CB (Global), GS (German), PSE (Japan), KC (Korea), UL, cTUVus, ETL, FCC (USA), SAA (Australia), CE, ROHS, REACH (European), BSMI (Taiwan) and so on. Check the certificates mark on the charger.

Check for the temperature when charging

When we are charging, the charger will heat up, which is a normal phenomenon. However, if the temperature of the charger is too high and exceeds a certain safety standard, then danger may occur. The surface temperature of the charger cannot be higher than 77 degrees.

Charger protection

A good charger protects the device against fluctuations in the power supply and even protects against over-currents. Remember that during a storm it is normal for there to be voltage surges. If you do not have a charger that includes this protection, your devices may be at risk.

All chargers from the Welink range protect against short-circuits and over-currents. That is, when the current exceeds a certain limit, the phone charger will automatically disconnect the circuit so that both the charger and the mobile phone are protected from “burning out” due to high current.

If you are an enterprise, please full test the sample and evaluate the charger carefully.

2. Charging speed –high power–

In the past, the original charger that output 5W or 10W cannot meet the needs of charging. Therefore, the fast charging technology has come out. The original and most popular types of fast charging standards are USB Power Delivery (or USB-PD) and Qualcomm Quick Charge.

Fast charging works only with devices supporting the USB Power Delivery (or USB-PD) and Qualcomm Quick Charge standard. With up to 100W of power available, Fast charger can even charge larger devices, like tablets and laptops. All you need is the suitable charger and cable – and leave those heavy laptop power cables at home.

The fast charge technology can intelligently recognize your devices and power your devices with the most suitable voltage and current, and maximize to improve the charging efficiency. A 45-watt wall charger will charge all your USB-C PD-enabled devices, but if you are looking to charge an iPhone X, which will only accept 18-watts of power, your 45-watt charger will only deliver 18-watts.

3. Size and weight

If you want to slip the charger into a pocket, then a small one, typically with less ports may be the order of the day. However, if space is not such an issue, then a larger one with more ports may be more suitable.
