As charging technologies continue to advance, it has become a lot easier for people to charge their devices faster and safely. The advancements have also led to the inception of better RAVPower portable charger technologies.
But there are so many technologies it can be hard to know what each one does—like what is a RAVPower GaN charger?
With that in mind, we’ve created this Charging Encyclopedia to explain in detail what each charging technology does—and its unique benefits.
Let’s get started.
iSmart by RAVPower (iSmart 2.0)
Each battery contains chips that allow it to control the current it receives from a USB charging device. Batteries control the current to maximize the charging speed and to prevent the damage caused by overcharging.
RAVPower’s iSmart charging technology adjusts the current and charging speed based on the battery specifications, helping extend the battery life of your devices.
iSmart charging tech automatically delivers the best power output according to the specifications of the device being charged. When you connect multiple devices to an iSmart charger, it optimizes the power output for each device.
iSmart 2.0 USB charging technology corrects any charging irregularities and protects devices against power surges, fluctuating temperatures, and electromotive force (EMF).
Want a RAVPower portable charger with iSmart technology? We have have two awesome and affordable ones: the 60W 6-Port Desktop Charger and the 40W 4-Port Wall Charger. They can charge several devices simultaneously and they offer protection against overcharging, overheating, and short circuiting. Thanks to iSmart tech, they quickly detect all connected devices, adjust the power output, and ensure the voltage stays constant to decrease charging time.
Qualcomm Quick Charge (QC) – QC 3.0
This charging technology was introduced in 2015 by Qualcomm, a California-based corporation that invents breakthrough technologies. Quick Charge 3.0 sustains high power delivery for charging while ensuring that power transfer is as efficient as possible.
A RAVPower wall charger with Quick Charge 3.0 can charge any device that supports the technology from 0% to 80% in 35 minutes. Quick Charge 3.0 uses intelligent negotiation for optimal voltage. It embeds an algorithm in your device to dynamically determine the exact amount of power it needs as it charges.
This allows it to draw the right amount of voltage from a battery. Because the voltage is well regulated, your device does not produce a lot of heat while charging or consume a lot of power, leading to your RAVPower portable charger saving energy.
If you want to charge your smartphone, tablet, or other USB device using quick charge 3.0 technology, get the Turbo 36W 2-Port RAVPower Wall Charger or the Turbo 20100mAh RAVPower Portable Charger. The airline-friendly power banks can charge a variety of devices and support all standard power grids.
Power Delivery (USB PD)
Power Delivery is a charging standard for handling higher power that allows a variety of devices to charge quickly via USB. When you connect two devices to a RAVPower PD charger, the technology facilitates a conversation between the devices so they can negotiate a power contract and determine how much power each one pulls from the charger.
Power Delivery can supply up to 10 times the wattage of conventional USB charging technology. It allows for very fast charging across all devices.
PD charging tech starts at 5V and can go up to 20V. It can handle up to 60W when a standard USB-C cable is used. When an EMCA cable is used, it can handle up to 100W. Many popular charging technologies cannot handle more than 36W.
Because PD charging tech can handle higher wattages, it can quickly power large devices like printers, hard drives, and laptops. PD also supports two-way charging. This means you can use your tablet to power your portable hard drive via a USB PD cable.
If you want a charger that’s powerful enough to charge a laptop, get the 20000mAh 60W PD Pioneer RAVPower PD charger. Read more about this RAVPower portable charger here. But if you want a RAVPower portable charger, we recommend the 61W 2-Port USB-C PD Wall Charger.
GaN Charging Technology
GaN (gallium nitride) is a compound with semiconductor properties. It is similar to silicon but offers more benefits because of its larger band gap. Band gap measures how easily energy passes through a material.
GaN has higher power handling capabilities, higher temperature limits, and 1000 times the electronic mobility of silicon. It is most beneficial when used in high-power wall chargers as this is where its band gap (3.4eV VS 1.1eV) can be clearly seen.
GaN is used in many ultra-fast charging devices because it offers better power and thermal efficiency in a compact area than conventional silicon parts. The technology shrinks the size of the RAVPower portable charger while ensuring safer, cooler charging.
A compact RAVPower GaN charger can charge high-power devices like laptops very fast. For example, our 61W PD Pioneer GaN Tech USB-C Charger can charge a 13″ Macbook Pro from 0% to 100% in just 1.8 hours. If you want a RAVPower PD GaN charger that can power two devices at the same time, get the 90W RAVPower PD GaN Charger.
Qi (pronounced ‘Chee’) is obtained from the Chinese word qi. It is an open interface charging standard that transfers power wirelessly using inductive charging. The charging technology was developed by the Wireless Power Consortium and can transfer power over distances of up to 1.6 inches (4 cm).
Most major phone manufacturers (including Samsung and Apple) have adopted the QI wireless charging standard. The technology allows you to charge an electronic device, like a smartphone, without a charging cable.
Qi wireless charging technology allows electricity to be transferred through the air via a magnetic field. When the transmitter (the charging pad) is plugged into a power outlet, it creates a magnetic field with the receiver (the device being charged). The receiver uses a special antenna to gather current which it stores in its battery.
If you’re in the market for a wireless charger you can use outdoors to charge your smartphone, check out our 5W Qi-Certified Wireless Charger. It is compatible with some iPhones, some android phones, and all devices that support Qi charging tech.
HyperAir Technology by RAVPower
Also called Over Air charging, this charging standard is more advanced than Qi charging technology. While Qi transmitters (chargers) must have a direct connection to the receivers (devices being charged) in order to charge them, this is not the case with HypeAir charging.
With Over Air charging tech, the receiver doesn’t have to be connected to the transmitter. When you enter a room with a Qi transmitter, your Qi-enabled device will instantly connect to it and start charging.
HypeAir technology is connected to True Wireless and the Internet of Things. And as 5G technology continues to advance, people will be able to make their whole lives smart. If you want to give this revolutionary technology a try, get the Turbo with HyperAir Wireless Charger. It can charge various iPhone and Samsung phones.
