Product Information

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. Power bank capacity: generally speaking, the more capacity a power bank has, the longer it will take for it to charge. So you can expect to reach a full charge much slower for a 72000mAh power bank for example, compared to a 5000mAh power bank. However, the difference between the charging time of these different capacities can be influenced by the next factor: In fact, our testing confirms what battery makers usually claim. A battery maker will claim between 60% and 70% efficiency, so that 10,000mAh battery will only give your phone around 6,000mAh of extra battery charge, at the least. In practice we find around 65% efficiency, though occasionally we can do even better. When you're after a power bank for a camping trip or weekend getaway, or to power your Switch or laptop, you'll want something with a higher capacity. Our power banks come in a range of powers so you can keep connected whether you're needing to charge your phone or your tablet device.

Most power banks now use a USB-C port to recharge, although some models will have a micro-USB port as well to ensure compatibility with older chargers. Don’t worry if you don’t have the required cable, as one will usually be provided in the box. Capacity:Think of capacity as the energy reservoir of your power bank. The higher the mAh (milliampere-hour), the more power it can store. So, choose a power bank with a capacity that suits your charging needs and can juice up multiple devices. Some of them supply more power and thus can charge a power bank faster, while others are slower and they can add several hours to the charging time of your device. Pre-charge level: If you charge your power bank when it’s 20% full, it will obviously take less time than charging it from 0%. Also, it’s generally recommended not to leave a power bank discharge to 0% on a regular basis, as it can affect the battery life in the long run.

What is the best power bank?

You have a watch that isn't from Apple: The Otterbox 2-in-1 Power Bank only attaches magnetically to the Apple Watch. Other smartwatches, like the Pixel Watch, won't work with this one, not at all. When it comes to charge times, there are a few different factors that might influence how long it will take for the power bank to reach that 100% level:

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. The OnePlus 8 series, OnePlus 7 series, OnePlus 7T series are compatible with 30W Warp charging and the rest of the OnePlus devices are compatible with 20W fast charging. Oppo F15, Oppo F11 Pro, Oppo Reno 2, Oppo Reno 2 Z support 20W and Oppo Reno 3 Pro supports 30W fast charging. If you've got one of Apple's iPhone 12, 13 or 14 models, there's a new breed of portable charger on the market. Output ports are used to transfer power from the power bank to your devices. Usually, this will be one or more classic USB-A ports. These allow you to plug in your own charger cable, meaning you can likely use whatever cable you’re already using to charge your device.

The Anker 525 features a PowerIQ USB-A port for fast charging all your devices and other equipment. As for the iPhone 15 Pro, the power bank comes with a USB Type-C port, which supports 20W of USB Power Delivery. It also has a capacity of 20,000mAh, which is enough to charge your iPhone 15 Pro up to 5 times. Additionally, the device also gets an LED indicator, which displays the remaining power and charging status of the power bank. If you care more about convenience than speed, wireless charging is very much the way to go – and a growing number of power banks support it. Just place your smartphone on the integrated wireless pad, and you can recharge without connecting any cables. There will be a hit on charging speeds, so you’ll be limited to 7.5W or 10W, but that’s not a big issue if you don’t need to recharge in a flash. As a bonus, we’re now seeing Magsafe-friendly chargers that will clamp onto an iPhone or a ring inside an iPhone case, meaning you can recharge your iPhone even while you’re using it.
