The Anker Prime series of Power Banks, including the Anker Prime 27,650mAh Power Bank (250W) and the Anker Prime 20,000mAh Power Bank (200W), are for people who truly love to geek out on power banks. If you came looking for the absolute best power bank you can buy, this is the best we've tried. It can charge while magnetically clamped to the iPhone and also (but not simultaneously) by USB cable at an impressive 18W, although you’ll need a USB-C-to-Lightning cable for wired charging. Wireless charging has become popular because it allows you to power up compatible devices without a cable. Qi is the dominant standard for compatible Android phones (up to 18W) while Apple iPhones rely on MagSafe charging (up to 15W). iPhones will charge wirelessly on Qi chargers, but only at 7.5W.
As such, it’s heavier and fatter (including the pull-out ring) than most other magnetic power banks tested here. Compatibility: MagSafe is specifically tailored for Apple devices, including iPhones, Apple Watches, and AirPods, while Qi wireless charging is a universal standard adopted by various brands. This is ideal for iPhone owners who like to use their phone while it's charging and don't mind paying a premium price.Speaking of that wall plug, it's the most useful feature ever on a power bank. Some power banks come with a built in USB-C cord, but this Anker comes with a two-prong power outlet plug. That makes it a wall charger as well as a power bank, and the utility can't be understated. In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty.
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. Some batteries include built-in output cables and these generally have micro USB, USB-C, or Lightning connectors.
Is MagSafe charging better for your battery?
Some battery makers have built Qi or MagSafe-compatible wireless charging into the surfaces of their portable batteries. Such batteries mean you can leave the cables at home. The good news is that the LED charge percentage indicator lets you know the remaining juice left in the charger. The bad news is that it is placed on the same side as the magnetic connection so that your phone covers up the display while attached. 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. The most important question to consider when buying a power bank is what will you be charging? If you are charging a small smartphone and that's all, a simple power bank will suffice. If you plan on charging a laptop occasionally as well, or many devices at once, you'll want something with more power and more features.
We wish there wasn't such an easy answer to this question, because competition is better for everybody, but Anker is making the best power banks right now by far. It offers the best power-to-weight ratio, the fastest charging, and the most useful features. But when you do need it, the Belkin 10K really delivers with a massive 38Wh (10,000mAh) battery capacity. Its 7.5W charging speed is also impressive. 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.
Stay Ahead of the Game
What it does offer is a massive battery capacity of 92.5Wh (25,000mAh), which should be enough to get you through a weekend festival. 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. 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.
Ports: Many of these chargers will come with extra ports, so you can charge other devices. Sometimes the ports are so you can charge the bank itself though, so keep this in mind. How We Selected Larger batteries with higher capacities might include a multitude of ports to support input and multiple outputs at the same time. You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common. We expect this competition will heat up next year as more power bank makers catch up and make faster charging batteries. Until then, Anker is the dominant brand, and if you want the best it's an easy choice. How many times can my power bank charge my phone?
