Doogee BL12000: This is how fast charging technology works

Where other smartphones use units of 3,000 or 4,000 mAh, the Doogee BL12000 integrates a battery of 12,000 mAh to offer the user a very high operating autonomy away from the power sockets. In these years, we use the smartphone every day to keep us connected with friends, and with the various services and autonomy has always been one of the technological limits of the entire sector.

For several years the low efficiency of the batteries, and the low efficiency of the charging process, has influenced the normal use of the smartphone, and that is why Doogee has designed a new charging system for BL12000.

Various manufacturers have tried to increase recharge speed, improving efficiency without compromising safety in previous generations. According to the charging principles used by the sector at present, the charging speed depends mainly on the output current and voltage, combined with the quality of the materials used in the cable.

In short, using a charging device to charge your smartphone is not much different than putting fuel in a car’s fuel tank: those who want to fill it faster can choose whether to increase the pressure from the mouthpiece to the machine, or use a larger one.

As far as battery power is concerned, increasing voltage and current is not easy due to the restrictions imposed by the cable and security in general. Doogee researchers have tried to use a different approach to market competitors who convert a low voltage into a higher value during the process, which obviously causes a marked rise in temperatures. Under the same conditions, an increase in voltage leads to lower efficiency combined with an increase in heat released from the battery.

The quick charge used on the Doogee BL12000 uses a power adapter that works with a voltage similar to the battery built into the smartphone. As stated by the company, there is no voltage conversion process during charging, so only a small amount of energy is dissipated in heat during the procedure, which also becomes more secure at the same time. Doogee claims to have managed to develop a quick-charging system tailored to BL12000 after months of work.

The 12V and 3A adapter is designed to charge the smartphone in 5 minutes to get 5 hours of battery life, with the full charge process that takes about 4 hours. Considering the specifications of the built-in battery it is an excellent goal, for a total autonomy declared of 42 days of standby time, 25 hours of video playback and 90 hours of calls. The smartphone has already captured the attention of lovers of great autonomy, and for more information.
