The problem with most backup batteries is that keeping your smartphone active, they are not a fast-rechargeable battery, and it takes a long time to recharge or not strong enough to provide more than one battery for a single refill smartphone. The power utility thinks they have solved this problem and created a fast-rechargeable battery that can be fully charged to the iPhone 5 smartphone in just five minutes. The Pronto Fast Rechargeable Battery Project is currently available on the Kickstarter website.
The most common battery pack gives you strength but takes half a day to charge. After waiting for up to 12 hours of power, the purpose of the failed portable power supply. By creating a battery pack that solves this problem from a battery pack on the wall outlet, Pronto charges up to 12 times more power than other batteries in the market today. Both models are filled with Pronto for an hour and come with a rugged hard anodized aluminum alloy housing. However, this is just the beginning of Pronto's charm!
Pronto5's streamlined design is ideal for everyday adventures. Equipped with a high-power 2.4 USB port, enough battery charging, iPhone5 3 times (4500 mAh capacity), it is small enough to carry anywhere. Pronto12 has a capacity of 13500 milliamps (9 iPhone5 power). It has dual high-power 2.4 USB ports and includes a 12V adapter that allows you to charge larger devices such as laptops, digital SLR cameras and drone batteries.

Silicone Rubber O Ring

Silicone o-rings are based on silicon, an element derived from quartz. To create this class of synthetic elastomers, pendant organic groups such as methyl, phenyl and vinyl are attached to silicon atoms. Different additions of side chains can achieve significant variations in properties. Silicone o-rings have excellent heat, ozone and corona resistance and have good dielectric stability and resistance to many oils, chemicals and solvents. Silicone o-rings possess the best flexible property at low temperature but have low tensile strength and poor wear and tear resistance.

Cure System: Peroxide-Cured
Standard silicone o-ring compounds are usually peroxide-cured. Platinum-cured compounds offer better flexible properties and very low volatile matter. Platinum-cured silicone o-rings usually are applied in medical systems or other required low volatile matter. However, they need to be produced in a clean room and with a higher cost of platinum catalyzer, making them more expensive than peroxide-cured ones.
