Car batteries are available even in remote places. When the adapter 12 volts, these batteries can be charged to your phone. Knowing how long you can keep the battery is charging the phone asks for some basic math skills.
Mobile phones often require mobile power supplies.
What Is The Battery Power
Car batteries, providing a solid 12 volts, but the current design of the battery changes. The batteries are rated in ampere hours, describing how many amps the battery to give a certain period. High amp hour batteries last longer than a small battery amp hours.
How Much Energy Using The Charger?
Mobile phone Battery Chargers powered by a battery and converts it into a voltage suitable for your phone. The introduction of the power to pick up the phone battery charge and quickly integrated into the faster the battery is low.
Typical Power Usage Leaves
The study was carried out Lawrence Berkeley National Laboratory shows a mobile phone charger, while charging the phone, use an average of 3.68 watts. Corresponds to the output current divided by the voltage, so that the phone charger drawing 0.3 amps average from 12 volt battery.
How Long Does The Batteries Last?
With a fully charged 200 ampere-hours will theoretically provide 20 amps for 10 hours or 2 amps for 100 hours. The charger draws 0.3 amps, the battery charger to run more than 666 hours ((20/0.3) * 10 amp-hours). Due to inefficiencies in the CANON BP-2L12 Camcorder Battery
, the actual time will be about 2 / 3 of it: 444 hours.
