How to charge handset battery by Bluetooth or WiFi?
Yes in fact wifi charging has been around for a couple of years and will be put into the public eye more this year. Especially by RCA.
In theory, yes... practically speaking, not so much... the power levels involved are very small, and the charging circuitry itself causes losses... you might be able to come up with something but it would take forever to charge anything. The concept of charging a device over a distance however is not implausible. Nikola Tesla powered a car(amongst other things) via wireless energy nearly 100 years ago. Read up on Tesla if you are interested in pursuing the idea further.
I don't think there is one for Android yet. Nokia has a few models that can do inductive charging, as it is called for the new Lumias.
Yes it can work in theory, the very old crystal radios worked with out a power source. A coil could be tuned to the standard wifi frequency then rectified to produce a dc voltage to charge the phone. The problem is that unless the signal is very very strong then the power produced is very very small
No, you can't charge via bluetooth or wifi.
In a word, No. As was mentioned though you can get an external battery pack. It depends on the phone but they start at around $25 and up. Or you could go with induction charging. This doesn't user wires but it does have to be touching the charger.
nope. still no way to do that! sorry, bt nokia has informed such a way by using wifi to charge! still in development.
not possible i think...but a great idea..
Dude this is 21st century, not 31st. There are however devices that can charge specific devices without touching but its called induction. I think it is impossible to recharge a device via WiFi or Bluetooth.
Bluetooth recharging is almost impossible as there is too little power to use for a rectifier to collect and convert to electrical charge. To increase to output of power would go against safety regulations in most countries. Wifi is a little more possible, but the efficiency of the power used for Bluetooth or wifi would cancel out most if not all power capabilities to try to recharge the device, making the recharge process take many hours if not days to recharge a battery, and that is if you don't use your device at all. Solar panel rechargers would be cheaper and more effective to use in any environment with light, or using wireless contact-point rechargers, which seems pointless to me as you still need your device on top of another device to make a charging connection to recharge the battery, defeating the whole wireless purpose since wires still allow for using the device at a restricted distance while contract-point has no distance option from the charging point, or you could use wireless induction charging, which allows for wireless recharging within a limited range (very short distance as it uses electro-magnetic fields to be able to convert into electrical charges
*to use for recharging the battery). For Bluetooth or wifi charging to work, the power must be at a high enough rate with a fairly large rectifier that uses a good amount of power to collect the radio waves would be necessary to get any amount of electrical energy feasible enough for a decent battery recharging time frame, which if it takes more than 10 hours to recharge a battery without much use of the device, would not make sense to use nor create such recharging devices.
Its not been made possible as of now....and it will surely take a long time to be made a reality and hit the markets as a product...
No, it is not possible.
I can't imagine how this should be realized. Bluetooth and Wifi both need energy if you use them - so ther is no way to charge battery...
It is not possible, i think...
Battery charging is like transfer for electric charge which can't be transfer via Bluetooth or WiFi
There are some devices can be found for wireless charging, like wireless charger with Qi standard for newly announced Nokia Lumia 920, where you can charge a handset just putting it on charger. I heard about inductive charging, but still this is only on papers and in labs.
This was a topic that I found fascinating. Hello again Sunil!
Not quite yet, but there's something called inductive charging, which wirelessly charges your device. Of course you have to put your phone on TOP of the charger.
I saw a killer deal on such a device on eBay earlier today, however, I've not heard much about inductive charging in general, other than that it works.
There was recently some talk about a lightbulb that was powered, wirelessly. It basically collects ambient radio waves and converts it into a light source. I imagine that the same technology can be used to charge a cell phone, but as you can see, it would require a redesign of the phone chassis.
thanks for your sincere answers
I remember this is not the first time you have answered my question in this forum
In reciprocation to your friendly replies : Here's Hoping that you could use your talent and knowledge of technology to serve the Supreme
It's my goal in life! Thank you for the kind words. :-)
There is a external battery charger. You can buy it and charge it. Then you can use that to charge your mobile when you are in travel. It will be very useful for you.
For this moment, i don't think there is such a device that meet your requirements.
What is the OS of your handset as the possibility may depend on if it is a Droid or a iOS, etc.
Buy a power pack if u want.
There are different brands who make power pack like sony, nokia and Belkin.
Power packs charge wirelessly?
