Shifting to Qi Wireless Chargers for Smartphones

By Sid Pranke –

Wireless chargers are now available for your smartphone and other devices. Many of the latest smartphones come with support for Qi wireless charging, but what exactly is that, and how do you use it?

Wireless charging means you won’t have to plug your phone into your charger anymore because it uses something invented by Nikola Tesla in the 1890s. (Yes, the same Tesla the electric cars are named after.) It’s called a Tesla coil, which transmits electricity without wires. If you have used an electric toothbrush, you may already grasp the concept.

To charge a smartphone, both the charger (such as the FosPower EnergyPad) and the phone have this type of coils inside, which are used to send and receive the charge. Developers of this technology explain how it works: “the charge passes between a transmitter and receiver coil placed closely together, usually only separated by the outer casing of the two devices (<7mm). The coils must be aligned to make the connection.”

Users and reviewers of wireless charging report that different smartphones have different “sweet spots,” so when first placing your phone on the wireless charger, you will notice when a good connection is made by your smartphone indicators.

Qi wireless charging & Qi-enabled smartphones

What is it Qi wireless charging? Qi (pronounced “chee”) is a wireless charging standard developed by the Wireless Power Consortium, which formed in 2008 and includes American, Asian and European companies in various manufacturing industries. Of course, the concept “Qi” also refers to a Chinese cultural principle that means “life force” or “natural energy,” so the Wireless Power Consortium obviously decided to play off that idea in naming its new wireless standard.

The FosPower EnergyPad is designed for devices with Qi-enabled wireless (inductive) charging ability, including:
Qi-Enabled Devices
• Google Nexus 6, 5, 4, 7 FHD
• Samsung Galaxy S6 / S6 Edge 2015
• Nokia Lumia Icon, 1520, 1020, 930, 928, 920
• Motorola DROID Turbo, Moto 360 Smart Watch, Droid Maxx, Droid Mini
• LG G2 (Verizon Only), Lucid 3 VS876, Lucid 2 VS870
The FosPower EnergyPad also works with:
Qi-Compatible Devices that require a separate receiver (such as the iQi Mobile, sold separately)
• Samsung Galaxy Note 4, Note Edge, Note 3, Note 2, S5, S4, S3
• Nokia Lumia 925, 822, 820, 810, 720
• iPhone 6 Plus, 6, 5s, 5, 4s

Features of the FosPower EnergyPad

Ultra-thin Profile

FosPower EnergyPad is one of the slimmest Qi-enabled wireless inductive charger available. Only 2.3mm thin, it makes charging less of a distraction, and more of a work of art. Polycarbonate material with rubberized coating that is smudge-free & highly scratch resistant.

Blazing Fast Charging

The EnergyPad provides a true 5V1A charge that complies with the Qi 1.1 standard. That is up to 40% faster than most wireless inductive chargers in the market. Embedded with a 12W GS certified future-proof universal power supply that works from 100V to 240VAC, it is capable of providing up to 5V1.5A for future Qi standards.

Low Energy Loss

Due to its unique design, FosPower EnergyPad generates up to 50% less heat than what is available in the market. With cooler and more efficient charging, it relays approximately 10% more power into your battery.

IP-67 Certified

Unlike most conventional wireless inductive chargers that are built using enclosures pieced together, FosPower EnergyPad’s unique material and construction ensures its internal components are completely water-proof, dust-proof, and accidental drop-proof.

EnergyPad IP-67 Certified















The IP certification system is administered by the International Electrotechnical Commission and can be broken down as follows:

  • IP stands for Ingress Protection
  • The first digit is on a scale of 0 to 6 and represents the level of dust protection the device offers (higher numbers are better)
  • The second digit is on a scale of 0 to 9 and represents the level of water protection the device offers (higher numbers are better)

So for the FosPower EnergyPad’s IP67 rating: the 6 means it is protected from total dust ingress (ingress means entry) and the 7 means it is protected from water immersion between 15 centimeters and 1 meter in depth.

How long does it take to wirelessly charge my phone or tablet? This depends on the size of your smartphone, tablet or other device but generally, for most smartphones, it will take several hours.

Can I keep it plugged in 24 hours a day? Yes, definitely.

Does it get hot? The EnergyPad’s unique structure and design generates 50 percent less heat than other wireless chargers.
