Portable Solar Charger Discharge Instructions

Portable solar charger is a solar energy conversion device, the solar energy into electricity after the battery stored inside, the battery can be any form of power storage device, generally by the solar photovoltaic cells, batteries, pressure regulator components of three parts

Solar Charger Product Type

Type one, with the lighting function of the solar charger, built-in super energy LED lighting, very power. If used alone for LED lighting, according to the built-in battery capacity can be used for 3 hours to 30 hours.

Type two, comes with a charging function of the solar charger, this charger does not carry any other expansion function. The advantage is that this type of charger capacity, is very suitable for professional external power supply.

Type three, support the power supply adjustable block solar charger. The current general support 5v, 9v can be transferred

solar panel

Now the market conversion rate of solar panels is still relatively low, generally only 16.5% of the domestic Suntech can do 17%, foreign people have done 25%.

Researchers at Rensselaer Polytechnic Institute in the United States in 2008 developed a new coating that will cover the solar panels to increase the sun's absorption to 96.2%, while the solar absorption of ordinary solar panels is only About 70%.

The new coating mainly solves two technical problems, one is to help the solar panels absorb almost all of the solar spectrum, the second is to absorb solar panels from a larger angle of sunlight, thereby enhancing the efficiency of solar panels to absorb sunlight The

Ordinary solar panels usually only absorb some of the solar spectrum, and usually only absorb the direct sunlight when the work efficiency is high, so many solar devices are equipped with automatic adjustment system to ensure that the solar panels and sun always keep the most conducive to absorption Energy angle.

The key to good or bad solar cell phone charger is four points:

First, the use of efficiency. The use efficiency includes two aspects: solar panel conversion efficiency and secondary conversion efficiency. The conversion efficiency of solar panels, as the name implies, refers to the efficiency of light energy conversion into electricity; and the secondary conversion efficiency refers to the efficiency of light energy stored in the battery after being converted into electrical energy.

Second, the battery quality and capacity. The battery capacity is typically 1.2 times the capacity of your cell phone battery. Solar built-in lithium battery discharge to the mobile phone and other digital products, energy conversion process will have energy loss, the conversion rate is generally 80% -90%, the battery so that the power of solar power is enough for your cell phone, so big battery can you The phone battery is full. The quality of the battery is also related to the life of the solar charger.

Third, the control circuit and protection circuit. The current solar cell phone charger product is very complex, it is inside the protection circuit and control circuit may be simple design, or poor compatibility, easy to fill the phone or reduce the phone and battery life. So the design of the control circuit and the protection circuit are very important.

Fourth, the solar charger accessories. This problem is often overlooked by many users, but can not be ignored. There are bad suppliers in the market for the price advantage and configuration of inferior accessories, such as AC charger (Common name AC adapter), AC charger with IC protection circuit or no IC protection circuit two. Unprotected IC AC charger not only charge current is small, the charging time is long and poor, and the hidden trouble. When purchasing a solar charger, pay special attention to whether the AC charger has circuit IC protection.

Solar mobile phone charger can only be used when the emergency can not rely entirely on it to the mobile phone and other digital products to charge, to achieve full charge to the phone, then the general needs of mobile phones solar cell phone charger solar panels greater than 0.7W.

Discharge instructions

Discharge, and the output voltage stalls transferred to the appropriate voltage to charge the product charge, and then you need to move the device according to the need to select the appropriate adapter, you can also use the USB plug to connect the digital products together.
