With a 6000mAh capacity, it will provide multiple charges on the go so you can use your phone freely, even on a low battery without worrying about battery life draining completely. With LED power indicators and a USB-C 18W PD input and output, it is a decent iPhone power bank at a reasonable price. FAQs What is mAh? Charging technology: if the power bank comes with a USB type C port and fast charging technology such as PD or QC that can sustain 30W+, then it will charge much faster compared to a power bank that has a micro USB charging port and a maximum input power of 18W. Due to this factor, you can find power banks with larger capacities that can charge faster than ones that have two times lower capacity overall. With the Realme 30W Dart power bank, Realme brings the first low voltage and high current power bank, and isn’t even expensive. This is an industry-first and the pricing is pretty sweet. For those who like to charge the device on the go while travelling (except 2020), this can be an ideal device to carry. This also eliminates the need to look out for a power outlet in public places or having to put up your device to charge slowly with other power banks. Lithium ion batteries, including most power banks, can be carried on planes as hand luggage, but should not be kept in the hold. You may need special permission to carry any battery rated at more than 100Wh (watt hours). That’s around 27,000mAh, which is quite large.

Yes and no. Most technically deliver on the mAh (milliamp hours) they promise, but that’s not the full story when charging devices. That’s because the batteries inside a power bank are 3.7v, while USB (which is used to charge your devices) runs at 5v. Since mAh is related to voltage, mAh changes when the voltage does. To further complicate matters, some energy is also lost through heat. The energy lost can be as low as 15% with some models, but can be much higher in others. There are also cool additional features to consider. Our favorite power bank has a built in charging plug so it can go right into a wall outlet. Some power banks have data about your charging devices. Some are just super small and cute. Which power bank is the best quality? With a portable charger or power bank, you can stay connected from wherever you are. Power banks are the perfect companion for outdoor trips, camping, holidays and long days out. That means I could twist my phone sideways into landscape mode and use the Baseus power bank as a portable stand for Apple's new StandBy mode, which is one of my favorite features on iOS 17, and certainly the one I use the most often.Power Delivery is a newer protocol in which two compatible devices negotiate on the fastest charging option available based on the charger, cable, and circuitry. It also allows for power to flow both ways. The use of USB-C for the single input/output port is a little weird given the target market, and you’ll need a fast USB-C charger and a USB-C to Lightning cable to make the most of the device. What’s more, the wired charging isn’t super-speedy; our Android test smartphone only recovered by 11% from a 15-minute charge. But if you’re an iPhone user looking for a light and convenient portable charger, the Anker 622 is almost perfect for the role.

Some batteries include built-in output cables and these generally have micro USB, USB-C, or Lightning connectors. The next question is how you want to charge your device. You can find a power bank that charges your phone (or even your Apple Watch) wirelessly. These will usually charge slower, but they can be very convenient if you want to leave wires at home. You need power for your phone: The 3,000mAh battery inside is plenty to keep your Apple Watch going, but that isn't enough power to get you even halfway charged on an iPhone 15, and even less on bigger phones.You may be asked for detailed information on the power bank. This is usually printed on the device, but can rub off with frequent use. If it’s close to the limit and you can’t prove it’s under 100Wh, be prepared for it to be confiscated.
