How Would You Go with Charging a 2.7V 3000farad Ultra Capacitor ?!? 1

I think you have misread the value of your cap. For general use you can consider a capacitor charged after 5 time constants(98%), for 120 seconds to full charge would be 120/5 or 24 seconds. the formula for the time constant is t (tau) = Resistance x Capacitance so 24 = R x 3000 or 24 / 3000 = R (the resistance in series with your capacitor) or 0.008 ohms. E = I x R or I = E / R 2.7volts / 0.008ohms = 337.5 amps Power = Amps x Volts 337.5amps x 2.7volts = 911.25 watts Check with any electronics shop and find out what you really have. edit: billruss is right, you can not do anything about the internal resistance of the cap and that would determine the charge time if you connected directly to your current source.

HTC Rapid Charge 2.0 overheating battery

Excessive Heating of battery is a typical, inescapable effect of using " fast or rapid " chargers. Reason behind this is the charging rate. Normal charging uses 0.5 to 0.8 C (C is the charge rate) whereas fast charging uses anything between 1 to 3C. In simple words, this is pushing more current to charge faster. Heat produced is related to Power and governed by the equation Power = I² * R where I is current. So increase in current has a significant effect on increase in power (being proportional to square of current) , therefore heating, and the same is being reported by your appYes, it does have adverse effects:Refer to my answer here for detailed technical explanation and a graph showing adverse effects How does fast charger work?Edit: A helpful note on heat increase while charging from All about Battery ChargersLi-ion should not rise more than 10ºC (18ºF) above ambient when reaching full charge

iPhone 11 Tip: How To Fast Charge iOS 13 Smartphone

The iPhone 11 has a fast charge feature which allows it to reach full battery with less hours plugged in. However, this feature needs specific hardware for the iPhone to charge faster. Here's what we know on how to use the iOS 13 fast charge on the iPhone 11. To use the fast charge feature on the iPhone 11, a 7.5W or higher charger is needed to quickly charge the iPhone 11. Once the iPhone is plugged in, it will take up to 2 hours to be fully charged. This charge rate is significantly faster from the regular 5W chargers that take 3 hours and several minutes to full charge. Reports have recently confirmed that many have adopted the iPhone 11 on its recent release this year. However, many of these early iPhone 11 adopters have opted for the base package for the smartphone. Apple only includes its regular 5W chargers for these bundles and does not come with Apple's own chargers. Fortunately, Apple offers its own fast chargers but costs around $50. The $19 USB-C to Lightning cable and the $29 18W USB-C charger are the Apple devices needed for fast charging. However, alternatives are available if Apple's own fast charging setup is too expensive. Third party fast charging with the iPhone 11 is also possible and also considerably cheaper than Apple's devices. Fast Chargers from Aukey, Anker, and Choetech on Amazon are viable picks for the charger. These fast chargers are cheaper than Apple's fast charger or offer more USB ports for charging many devices at once. Lastly, the third party USB-C to Lightning cable is a must have for the fast charging setup. The USB-C end is for the charger's end and the Lightning tip is for the iPhone's charging port. Again, the aforementioned companies also carry these cables on Amazon too. These cables may be costly but users will be able to save money with these setups better. The Fast Charging feature on Apple rapidly charges the device up to 80 percent and slowly charges the remaining 20 once the uses the device the while charging it. Overall, the new fast charging feature is great for Apple owners on the go.
