5/7.5/10W? What does all this mean?
Wireless chargers have various power outputs, the minimum is 5W. Many wireless-enabled charging devices support 5W, 7.5W and 10W wireless charging. If a device is 7.5W/10W, it is considered fast-charging. Wireless chargers that support 7.5W/10W are preferred over the 5W chargers because they charge the device much faster. 5W chargers are usually what is provided with smartphones even if they support fast-charging.
Quality wireless chargers come standard with smart chips that regulate the amount of power that is delivered to the device. For instance, if the device is 5W and the charger is rated up to 10W, the wireless charger will recognize that the device only needs 5W of power and will deliver just what is required.
Are wireless chargers safe to be around?
Yes, they are! It is safe to be in close proximity of wireless chargers and charging devices for extended periods. Chargers that are not in use emit a harmless signal that looks for a wireless charging receiver, like the one in your smartphone. The signal emitted does not extend past the maximum distance specified on the wireless charger (3mm to 10mm). Provided that the wireless charger meets safety regulations set by organizations like the FCC in the United States and CE in Europe (like all the devices supplied by Toddy), they will emit less radiation than a phone connected to a mobile network.
Can a wireless charger be used anywhere?
Yes, they can be used anywhere! To ensure that the wireless charger is safe to be used anywhere, including hospitals, the wireless charging frequency needs to be strictly controlled at the manufacturing and QC stages and it’s: 110-205khz. Huh? Yes, that is what we thought too, but this is very important. The 110-205khz frequency means that the wireless charges will not affect the normal operation of surrounding wireless devices.
No interference with devices such as hearing aid, pacemakers or other devices. It will also not interfere with any devices that use Infrared (IR) Technology like thermometers, pulsometers, tonometers, etc. that hospitals rely on, making them safe to use in any healthcare application.
Will the charger get hot?
All charging devices create heat as they charge. The heat that comes off the charger is a loss of energy. The most efficient chargers are the ones that go through extensive efficiency testing to minimize wasted energy through heat. The best wireless chargers have built-in safety protocols that will automatically turn off if excessive heat is detected to protect the charging device.
Can a wireless charger overcharge the device?
It is perfectly safe to leave the smartphone on the wireless charger for prolonged periods. Wireless chargers use what is known as trickle charging. Trickle charging is when the device battery gets below 100% while still on the wireless charger a small amount of current will start to trickle, ensuring that the device is kept charged at all times.
