Today, people use many electronic devices, some with built-in batteries, like new smartphones and laptops. Smartphones are always with you; portable chargers are needed to charge your phone anywhere.
Smartphones or cameras need memory cards. They are used when the device has only a token amount of memory. This is where only a few files can fit or, as often happens with cameras, photographers have to store many high-quality images.
Like smartphones, people often carry laptops and must be charged while working. However, it is essential to choose quality laptop stands to make working anywhere comfortable.
How to choose a battery charger?
Disposable cells in any device eventually wear out, and consumers often buy rechargeable batteries. Incompatibility between batteries and chargers is sometimes the first mistake they need to correct. To understand how to choose it correctly, you must first understand the operation principle. The chargers bring the mains voltage - 220 volts to the level of the accumulator, and accordingly, they differ in volume.
Also, it is essential to note that the chargers should also fit the cells.
- Nickel-metal hydride (Ni-MH) and nickel-cadmium (Ni-Cd) batteries are available in the most common sizes, AAA and AA. Standard sizes are AAAA, C, D, SC and Krona. The typical voltage of such batteries is slightly lower than that of other similar batteries - 1.2 V instead of 1.5 V. The only exception is Krona standard-size batteries - produced with 7.2 and 8.4 V voltages.
- Typical lithium-ion (Li-ion), lithium-polymer (Li-pol), and lithium-iron-phosphate (LiFePO4) batteries are available in cylindrical cases of various sizes (10440, 14500, 14650, etc.).
The numerical designation on the cylindrical case corresponds to the length and diameter of the battery - for example, an 18650 battery has a diameter of 18 mm and a height of 65 mm. However, these dimensions are not exact - for different manufacturers, the case sizes may differ slightly; also, models with a built-in protection circuit are several mm longer.
