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. Power banks above 20k mAh start to get fairly heavy and less portable, but they’re great for folks looking to charge a larger device such as a laptop on the go. If you’re searching for a bank that can handle the demands of laptop charging, around 20k mAh is the bare minimum capacity you should consider. On this list, the Goal Zero Sherp a has an impressive capacity of 25,600 mAh. The Lion Trek is another excellent high-capacity power bank — and it even sports a standard three-prong AC outlet. Charge Times and ‘Fast Charging’ Smartphone batteries are becoming larger and more efficient. In our experience, 10,000 mAh power banks will charge a modern smartphone between two and three times. On this list, the Nitecore NB10000 is the most impressive 10k mAh power bank that we tested. It fully charged an iPhone 13 two and a half times. 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.

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. 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. In general, any charging source that can deliver around 15w or more could be considered “fast charging.” Comfortable and Safe Design]: Newest skin feel streamline design, The Ergonomic design fits comfortably and stylish in your palm; besides, the rechargeable power bank is equipped with multiple safety protection including overcharge, overheat, short circuit, etc; which improve your safety and prolong battery life; It weighs less than a 500ml bottle of water, a little heavy but great choice for camping, traveling, hiking or other outdoor activities.We’ve been testing the Lion Trek for several months. Though it’s a bit too big and inconvenient for airline travel, it’s been our go-to power bank for car camping. On a single full charge, the Lion Trek recharged an iPhone 13 nine times. It kept a MacBook Air alive for three days of frequent use. According to its display, the Lion Trek only used 5% of its total battery life to fully charge a pair wireless earbuds. 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.

These days, many devices including phones, power banks, tablets, and cables claim to support “fast charging.” In reality, there is no universal standard for what “fast charging” really means. Each individual device has specifications that determine how much wattage delivery it can handle. Every element in the charging system — phone, power bank, and cable — plays a role in the rate of power delivery.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. For example, early iPhones came with a 5W power adaptor in the box. Those 5W adaptors took over two hours to charge standard smartphones. On this list, the speedy OtterBox Fast Charge delivers 18W power — it can fully charge an iPhone 13 in just over 90 minutes.

The next standard portable power bank size is 20,000 mAh. Not all power banks in the 20k range will have a capacity of exactly 20,000 mAH — that’s just a handy benchmark figure. Naturally, 20k power banks are bigger and heavier than their 10k little siblings. Most 20k banks weigh at least one pound and are roughly the size of a small tablet or jumbo candy bar. 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.

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. 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? All smartphone manufacturers utilize different batteries and charging systems. The working capacity of any power bank entirely depends on the device it is charging. Most fully charged smartphones contain 3,000 to 4,000 mAh, That means, on paper, a 10,000 mAh power bank can recharge a smartphone about three times. Editor’s Note: In November 2023, we updated this article to provide additional information on how we tested and evaluated power banks. The Best Power Banks of 2023 Some larger power banks are equipped with wireless charging capability. On this list, the Goal Zero Sherpa 100 PD comes with a wireless charging pad that can deliver up to 15w of power to compatible devices. In general, wireless charging from a power bank will be slower than using a cable, but it’s highly convenient in certain situations.

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. 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. Power banks are physical stop gaps that prevent dreaded cases of DPS (dead phone syndrome). Whether you forgot to plug in overnight, or you’ve been traveling all day without access to an outlet, power banks are a lifeline for you and your portable electronics. Unlike most power banks on this list, the Flip 24 only has USB-A input and output. It’s not surprising for such a small bank, but it might be annoying for folks without a compatible cable. Plus, USB-C charging tends to be faster than USB-A. The Flip 24 will charge your phone slower than most other options on this list. 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.
