Home iPadia iPad Accessories ,,,,, We have already talked about that particular category of emergency batteries which, in addition to being able to restore the energy of smartphones and tablets, can also start the car in breakdown thanks to the help of two terminals to be connected to the battery of the same. RavPower RP-PB063, recently tested in the editorial office, is one of these, which stands out for its high starting current, equal to 1000A, therefore close to that of specialized boosters.
Com 'is done
The battery is stored inside a semi-rigid fabric case together with the cables with pliers for connection to the car battery, two microUSB cables of different lengths and a wall charger.
It is not one of those emergency batteries that you will carry in your bag or trouser pocket all day, this is because weight and size certainly do not make it a pocket solution. Of its 14,000 mAh capacity, you will certainly find more portable batteries, if your goal is solely to restore energy to smartphones and tablets on the move.
RavPower RP-PB063 is rather a battery that will remain closed for most of the time in the trunk or glove compartment of the car and will only be taken out in the event of a malfunction in the car or during a picnic or a picnic, where you will park. the car only a few hundred meters away.
The battery body is really massive, very robust and apparently capable of withstanding even a possible fall of a few tens of centimeters. The LED flashlight is recessed on one of the two short sides, on one long side we find an LED indicator and the Boost button, on the other hand the microUSB input, the ON / OFF button and three USB-A sockets, one of which recognizable by its green color and equipped with Quick Charge technology.
Booster mode
This device, like all the other batteries with booster function on the market, is not able to start the car or motor vehicle “from scratch” when the battery of the latter is completely discharged. The user manual included in the package confirms that booster operation can be applied when the residual energy in the vehicle battery is not less than 60%.
In addition to this, other factors also come into play such as the power of the original battery, the displacement, the type of vehicle (diesel cars are hardly able to benefit from the help of a booster like this) and so on. The technical data says that the inrush current of the Ravpower battery is 1000 A, the starting current of 800 A, a very high figure compared to other products that have an inrush current of 400 – 500 A and close to that of some specialized starters always with USB ports that is around these values (1000–1200 A), although some even reach 2400 A and therefore can totally take the place of the car battery.
The inrush current is the most relevant aspect in a booster, because the ability to start the machine depends on this specification, Ravpower also promises 20 start attempts with a fully charged battery; in practice, assuming that there is enough energy inside the Ravpower battery (more than 20%) and that the car battery is not too discharged and that the car is not of a high displacement, you can try to turn the key about twenty times.
Emergency battery mode for smartphones and tablets
RavPower RP-PB063, we said, offers 14,000 mAh which, perhaps due to the particular configuration, has a modest yield compared to other competitors. In fact, we measured around 9,500 mAh, in practice about 30–35% of energy is lost in the transfer.
As for the power, according to the manual it supplies 2.1 A for each socket, which we confirm as iPhone 7 at 44% of energy and iPad mini 3 at 51% of energy are recharged respectively at 1.81 A and 1.96 A. To deliver up to 3A it is instead the third USB socket, in green, with Quick Charge, which, however, can only benefit the latest generation devices equipped with this technology.
When discharged, the battery recharges quite quickly: thanks to the charger included in the package (or any other with 2A output) 6.5 hours are enough to completely restore the energy, a considerable advantage compared to other 14 thousand mAh batteries that absorb only 1A and which can therefore take up to 10 hours or in the best of cases 8 hours.
Conclusions
RavPower RP-PB063 is definitely a niche product dedicated to those who want to feel safe while traveling and who do not want to invest in a specialized booster by opting for a solution that is certainly less bulky and versatile since it can also charge three devices at the same time and at maximum power. .
Retail price
RavPower RP-PB063 is on sale on Amazon for 92.99 euros.
