How efficient is the wireless phone charger?

Wireless phone charging offers many conveniences. You can charge your phone virtually anywhere and don’t have to worry about wires or cables.

For most people, that’s enough. They don’t really worry about how long it takes or the efficiency of the charger.

That’s because they don’t realize that most wireless chargers produce unnecessary heat, resulting in slower charging times and more wear on the battery. These inefficient chargers also use more electricity so – in addition to waiting longer for a full charge and replacing batteries more frequently – their electric bill is also rising.

Sunvalleytek International Inc., a California-based high-tech manufacturer, has come up with a new, cutting-edge approach that addresses all of these issues. Using its patented HyperAir technology, Sunvalleytek recently launched a line of wireless chargers (RAVPower) that features triple temperature controls to avoid overheating.

RAV stands for Reliable, Affordable, Value.

An “intelligent chip” monitors and controls the charging temperature for optimum performance. Additionally, sophisticated modifications of the internal structure disperse heat 15 percent faster and more effectively than traditional wireless chargers.

RAVPower chargers also use specially-designed circuitry that prevents overcharging, over-current, over-voltage, overheating and short circuits. The result: charging times that are half of traditional 3.5-5W wireless chargers.

For example, an iPhone X, 8 or 8 Plus can fully charge in 152-167 minutes. A Samsung Galaxy S8 can charge in less than 240 minutes.

The economical RAVPower-PC066 hit the market in late January. RAVPower-PC069 and RAVPower-PC080, which offer additional features, were launched in mid-February.

RAVPower-PC080 features

The RAVPower-PC080 includes a 10400mAh Qi 7.5W fast wireless charger for iPhone X, 8 and 8 Plus, and a 10W Qi wireless power bank for Galaxy S8, S8+, S7, Note 8 and all Qi-enabled devices. Non-Qi enabled phones will require a Qi wireless charging cover to power up.

The 10400mAh charger also enables you to charge two devices simultaneously, thanks to a wireless charging top surface and a USB port.

In addition, this model offers Instantaneous Device Detection. By sharing the same fixed frequency program as iPhones, the HyperAir technology accurately detects an iPhone (or other Smartphone) and starts charging immediately.

The result is a faster, safer charging system that uses less electricity.
