Advice 1: How to charge solar battery

For efficient operation of solar energy needs the sun. Best of all, it will charge on Sunny day in open space. Providing a constant flow of ultraviolet radiation on the surface of the device, it is possible to achieve a full recharge.
How to charge solar battery
You will need
  • Cleaner for glass alcohol-based, soft fabric, solar charge controller, solar light.
Instruction
1
Before sending the surface of the solar battery to the light, make sure it is clean. Carefully inspect it. If the surface is dirt, wipe gently with a cloth impregnated with liquid glass cleaner alcohol-based.
2
In winter, solar panels that provide power at home, must be free from snow. Shake off the snow cover and carefully remove the icing.
3
Carefully inspect the place where a solar battery. Remove the obstructions that can block the surface from the sunlight.
4
Check out how the charge controller. Start the battery only with a proper instrument.
5
If the charge controller has failed, replace it before you use the battery. You can buy the cheapest version of the device - ON/OFF controller. He just disconnects the solar panel from the battery when congestion occurs. There are controllers PWM (pulse width modulated converters), which reduce tension in the solar battery to the required digits and maintain it at this level. It is best to use such devices, because using the ON/OFF or disconnecting the battery will result in a permanent incomplete charging of the batteries and they will last significantly less than those regularly charged to 100%.
6
If no controller is necessary to monitor the charging voltage with a voltmeter. When it reaches the desired numbers, the battery must be disabled. If time does not disable it, it will overcharge, the boiling of the electrolyte and reduce the battery life.
7
In order to charge a solar panel on portable devices, it is necessary to clean contamination from the surface. The purification method is similar to that used at solar power plants. After this, the instrument must be put into the sunlight. If there is no battery charging indicator, on the average it is necessary to expose it to UV for 30 minutes.
Note
The need to release the battery from the snow is that snow, even the thinnest, don't let the sunlight in.

The battery will last a long time if there is a charge controller which protects the battery from over-charging and deep discharge.
Useful advice
Frost is better to clean with a damp cloth and then wipe the surface dry. You should not use scrapers to avoid scratches.

Wipe the dust from the solar panels located on the street, it is necessary twice a year.

Advice 2: How to charge phone without charger

I'm sure many have faced such a problem, such as discharge of a mobile phone during some of the trip. Sometimes an accident happens at work and, unfortunately, none of colleagues is no suitable charger. What to do in such a case, how to charge a mobile phone in an alternative way?
How to charge phone without charger
Instruction
1
If you often face such problem, purchase a special device that plugs into a USB port and charges the mobile phone battery.
Connect this device to your laptop or computer and thus charge your phone.
2
If you go camping, bring a radio receiver, because it can not only broadcast radio, but also charge your mobile phone. The receiver is equipped with adapters for different mobile phones.
3
Use the solar charger TYN-94, which is able to charge cellular in nature, at the cottage or on the road.
4
Use a special device GP Instant Power GPXPG01, running on AA batteries size-AA batteries. This device will charge your phone when the power at any time and in any place.
5
If you actively use all the possible functions of the phone, and he often runs out of power, then buy a special device FreePlay ZipCharge, which produces the cell be recharged in just a minute. The device itself is charging from the electrical outlet, but it will take just 15 minutes. Battery, which is the basis of the device for 10 minutes, restored 90%, and for 15 minutes at 100%.
The mobile phone rarely discharged, learn how to save battery power: adjust the display brightness, turn on the sleep mode, turn off the sound when you press keys, all sorts of reminders and alerts, set your phone to silent mode.
Note
"How to charge your phone without charging"? What to do with the phone charging where to get that outlet? Calculations show that if the cell phone battery has a capacity of 500 mA (this, of course, a very old phone), it is necessary to include in the circuit a resistor of 100-120 Ohms (while the charge current will flow 40 to 50 mA or 10% of the nominal, and the way that I conducted confirmed measurement).
