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.

If you have a newer Android phone, or the latest iPhone 15 models, you'll want a power bank with faster charging speeds to get your battery full faster. Charging speed is measured in wattage, and the iPhone 15 can charge just a bit faster than 15W, while the Galaxy S23 Ultra can charge up to 45W. What You Get: Anker Prime 27,650mAh Power Bank (250W), Anker 100W Charging Base for Anker Prime Power Bank, 2 ft / 0.6 m USB-C to USB-C charging cable, power cord for charging base, travel pouch, welcome guide, our worry-free 24-month warranty, and friendly customer service. Everybody on our gift list who got a new iPhone is going to get an Anker Nano Power Bank (22.5W) this year. This cute little charger is perfectly sized to sit beneath your favorite smartphone, plugged into the USB-C port with a little plug that opens out or hides away for a sleek look. We have tested the best power banks by using them to charge a variety of devices, including Apple iPhone, Google Pixel, and Samsung Galaxy phones. We have also charged Apple iPad tablets, and small laptops including a Pixelbook Go and a Surface Laptop Go. 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 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. The EB55 has a maximum total output of 700W, bar the odd 1,400W surge, so we couldn’t test it with the heater we normally use to test big batteries like this. However, it ran a 42in LED TV, drawing 72W to 75W, for 5hrs 27mins, making it through the first two Hobbit movies in the process. If you want to run kettles or coffee machines then you’ll need something with a higher output ceiling. If not, this is a brilliant compact solar generator at a thoroughly reasonable price. You only want to charge a phone: If you don't need to charge a laptop occasionally, or you only carry a phone with no accessories, the Anker 733 is more than you need. 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. With a power bank, though, you can always get a recharge – even when you’re far from home. In fact, with bigger power banks, you can get away for a weekend or go camping and still keep your phone juiced up. And it’s not only smartphones that can benefit. Tablets, digital cameras and Bluetooth speakers can often do with a top-up, and a decent power bank is a must-have accessory if you love playing on a Nintendo Switch.

Small Size, Huge Power: The power bank is the size of a soda can with a capacity of 27,650mAh and can charge a MacBook Air (M2) 1.28 times or an iPhone 14 approximately 4.67 times.You don't have a magnetic phone: You don't need an iPhone to enjoy the magnetic charging, but you'll need a case that lines up your phone with Apple's MagSafe wireless configuration, or else your phone won't charge properly.

Get Real-Time Information: Stay informed with the smart digital display that provides real-time information on remaining battery capacity, power input, and power output, giving you complete control and visibility over the power bank. You don't need all those extras: The Anker Prime power bank is pricey, and if you don't care about monitoring charge Wattage or days of battery life, find another option.Tylt also wisely left enough of a gap between the battery and the bottle that you can coil a small USB-C cord (included) into that space. That way, even if you're not charging wirelessly, you're not adding a lot of extra bulk to your bag. It's a smart setup. 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. It’s neither the speediest solar charger nor the fastest charging power bank, but it’s a handy and affordable option that could work well on a hike or camping trip. There are plenty of other power bank makers around, and most of them have not caught up to the faster charging speeds available on the iPhone 15 family, let along even faster Android phones. Except for unique form factors or serious bargains, we stayed away from recommending power banks from reputable makers if they couldn't charge at 2023 speeds.
