Charge both your watch and phone simultaneously using 2-in-1 wireless chargers for iPhone and Apple Watch.

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. The iWalk Link Me Pods is an wireless charger powerbank for mjultiple devices. It not only supports wireless charging, but also has a USB0C port and one built-in charging groove foor AirPods. It allows 3 devices to be charged at the same time.

Apple Watch brings a host of utilities to the table. That said, the smartwatch offers average battery life, at best (unless you have the Ultra, of course). In particular, the wearable’s one-day battery life is a no-go, especially when you’re traveling. And with no power outlets to top up the device when you’re on the road, a wireless power bank for the Apple Watch would be a game changer.

You can also charge the Anker Prime using both USB-C ports at the same time, for a combined recharging rate up to 170W. That means you can completely refill this whopping 27K mAh battery in under 40 minutes. I thankfully had an Anker 737 GaN Prime charger that was up to the task, and it's fun to see the percentage climb. Anker batteries also look great and are built with high quality parts. The display on our best battery for power users is bright and sharp OLED display, totally unnecessary for a power bank, but that's what makes Anker the best. It far exceeds our expectations of what's necessary to make power banks that are great. The Anker Nano is only 5,000mAh, but that doesn't mean it can fully charge a 5,000mAh phone battery like you'll find in the Galaxy S23 Ultra. Power banks are about 60-70% efficient, depending on the phone's technology, so this power bank is good for charging an iPhone 15 to nearly full, but that big Ultra will only get about 65% charge.

The best iPhone power banks of 2023

The best power banks we have tried have all come from Anker, but that doesn't mean Anker is the only brand you should consider. All of the power banks on this list passed our testing, traveling with us on the road and powering our devices at home. Anker is the best, but these batteries from Baseus and Otterbox performed well.

You need a lot of power: Thankfully, the battery on the Tylt Bottle 2 isn't so big it adds too much weight, but that also means it isn't powerful enough for multiple charges. Thanks to the 3 integrated cables and the possibility of wireless charging, the Scorpion Air Plus can charge up to 3 devices at the same time, whereby the Scorpion Air Plus can also be charged directly with the Pass-Trough function. The Scorpion Air Plus also has a lightningIN and USB-C input port, whereby the USB-C acts as both input and output with the option of PD and QC. Due to the strong housing but also due to the silicone texture, the power bank has a strong grip and your phone does not slip while charging. For the uninitiated, Apple’s MagSafe tech helps latch the device onto an iPhone magnetically. Needless to say, the charging speed isn’t the best when you use the power bank in tandem with MagSafe technology. In fact, you’ll have to top up your device at just 7.5W. Thankfully, the company’s power bank comes with a Type-C connector that can output at 20W.There are plenty of combination power bank and some other device, but the Tylt Bottle 2 actually makes sense because we're usually carrying an insulated water bottle anyway, so we might as well screw a battery onto the bottom. With a 5,700mAh capacity, the Tylt Bottle 2 is just enough to get us through a very busy day, or keep the phone powered while we play games at the cafe. Our favorite power bank has a 10,000mAh battery, and the Samsung Galaxy S23 Ultra has a 5,000mAh battery, so the math should be simple, right? It charges twice. Except that's not how it works. Power banks are not 100% efficient, and even though you start with plenty of power, a lot of it is lost in the charging process. Are you looking for a wireless charging solution for your Apple Watch that can recharge your iPhone in a jiffy too? Then, you should give the iWALK portable Apple Watch power bank a second look. The integrated magnetic charger module and lightning cable offer the best of both worlds. The icing on the cake is that you can use both ports to charge two devices simultaneously. On the flip side, the power bank doesn’t come with a display to shed light on its battery level.

You want a more portable option: Because of its combo nature, the Anker 733 is a bit bulky and cumbersome, but if you use it both ways, it's worth the trade-off in size to have such a useful device.

Which iPhone power bank is right for you?
