The Type A (flat parallel-blade design) Apple 5W USB, 18W, and 20W USB-C power adapters, as well as the 10W and 12W USB power adapters (with Type A AC plug attached) also comply with the IEC/UL 60950-1 and IEC/UL 62368-1 standards for use with power sources rated to provide 115V AC at 400Hz.
An iPhone and most Android smartphones need at least one amp (five watts), for example, while an iPad and other tablets expect 2.4 amps (12 watts). It’s important to get this right. If you've ever tried to charge a new iPad from an old phone charger, for instance, you’ll be well aware of what happens otherwise: very long charging times or The iWalk mini portable battery pack features a built-in lightning cable, making it the perfect iPhone companion on the go. No need to carry any extra cables — score! It can fast charge your iPhone 14 up to 40% in 30 minutes. You can charge an iPhone 8 up to four times, and an iPhone 14 up to two times when iWalk has 100% battery. Nyko, Apple. All models of Nintendo Switch use USB-C for the charging port on the bottom of the unit. So, in a pinch, you can charge it with any USB-C cable plugged into a power source, such as a tablet/smartphone charger, battery pack, PC, or USB hub. The speed at which the battery recharges (and whether it actually powers the Switch for play
The iPhone 6 battery has 1810mAh, the iPhone 6 Plus has 2915mAh. In our tests, an iPhone 6 can be completely charged in about 1h 15min, the iPhone 6 Plus needs between 1,5h and 2h. That’s almost twice as fast as Apple’s included power supply, which needs 2 - 2,5h for the iPhone 6 and 3 to 3,5h for the iPhone 6 Plus.

1 - Estimate how much charge your phone holds. Let's say 2000mAh 3.7V battery, so ~ 8Wh. 2 - Lets say you fully charge your phone every day. 3 - Lets assume the charger circuitry in your phone has 80% efficiency and the USB PSU 60%. So charging your phone wastes 50% of the energy. That's 16Wh per day. ~6kWh per year. Standard rate: 0.1C. A standard bulk charging rate for AGM batteries is 0.1C. This expression means a charge rate that adds 10% of battery full capacity each hour; put another way, this rate would charge a battery from empty (0%) to full (100%) in 10 hours. While such a charge actually takes longer due to the slower absorption stage, the C-rate G7rcl.
