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. 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. How we test power banks 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. Now, let's talk about charging speed. The PowerIQ Charging Technology integrated into this power bank is a game-changer. It automatically detects the device connected and delivers the fastest possible charge, ensuring that I spend less time waiting and more time enjoying my adventures. Whether I'm charging my iPhone or my Samsung Galaxy, the Anker Portable Charger handles it all with lightning speed.

The bottle is actually a nice, insulated affair, and it kept ice in cold water for 12 hours, which is all that we need. It has a good, strong strap to carry the bottle, though we would have liked a lid that was easier for sipping. Connect an 18W charger (not included) to the USB-C port to fully recharge the internal battery in just 4.5 hours. Our durability test involved prolonged regular use indoors and out, and a standardized drop test. Every bank was dropped exactly 2 feet onto a concrete surface to simulate the classic electronics fumble that we all experience from time to time. Some power banks ceased to function after a single drop. Of course, none of those models made the list. No integrated cables: It does not come with any built-in cables or adapters. You'll need to use your own cables to connect your devices to the power bank, which can be inconvenient if you forget them or lose them. Some power banks have integrated cables or magnetic connectors that make them more convenient and portable. 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 2023Brand Reliability: When it comes to portable power banks, it's essential to choose a trustworthy brand.

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.

Use the included Micro-USB cable, your original cable or a third-party certified one (such as MFi); AC adapter not included.

Don’t get stuck without a charger for your gadgets. We’ve picked out the best power banks to help you recharge while you’re on the go

The most common kind of input port is USB-C — the same port found on all modern iPhones. USB-C ports are easy to use, efficient, and durable. 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. 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.

Read the Instructions: Take a few minutes to read the user manual that comes with your power bank. Familiarize yourself with its features, usage instructions, and safety precautions. This will help you make the most of your new gadget while keeping yourself and your devices safe. Most of the power banks on this list hold around 10,000 mAh — a standard size for recharging small devices like smartphones, Bluetooth headphones, and smartwatches. Though brands often claim their 10,000 mAh power banks can recharge smartphones five, six, or seven times — they rarely live up to those claims. Anything with 20,000mAh or above will charge your phone multiple times, and many can charge several devices at the same time. As such, they're usually larger, weightier and can be more expensive.

The best portable chargers for more demanding users

Using the Anker Prime power bank, we were also able to test the charging speed claims of other power banks, as the Anker Prime will report charging speed in wattage. mah power banks can be trustworthy and travel-friendlypower sources for charging electronic devices such as smartphones, tablets, and other USB-powered devices. Looking for a reputable and quality power solution? Anker's 10000mah power banks are designed to keep your devices charged anytime, anywhere. With acompact size and powerful capacity, you'll never have to worry about running out of battery on the go. 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. The first MagSafe power bank on our list is the Anker 621 Magnetic Battery (MagGo), which stands out as one of the most compact and powerful options for a MagSafe power bank. Here are some key features that make it deserving of its spot among the top choices: That app is essential because there's a Find My feature built into the battery. It doesn't work like an AirTag over UWB, it's only Bluetooth, but it's useful if you misplace your battery in your office (or you have multiple batteries, like I do).
