Effortlessly locate your power bank with sound alerts, monitor real-time stats, and utilize smart charging for extended device battery life. Small Size, Huge Power: The power bank is the size of a soda can with a capacity of 27,650mAh and can charge a 13-inch MacBook Air (M2) 1.28 times or an iPhone 14 approximately 4.67 times. Please know that this power bank is 99.54Wh, which meets the requirements of the TSA(<100Wh) to be taken on airplanes as carry-on baggage. 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. Dimensions: 9.91 x 6.4 x 1.65 cm | Weight: 173g | Capacity: 5,000mAh | Ports: USB-C (input and output) and wireless charging To ensure proper functionality, please remain within a range of 33 ft (10 m) from the power bank when using the app, as it connects to the power bank via Bluetooth.
When it comes to purchasing a power bank, there are a few important factors to consider. Let's dive into them: 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. 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.Apple has added its clever “MagSafe” tech to every iPhone (other than the SE) since the iPhone 12. It uses magnets to ensure perfect alignment for a range of accessories including wallets, wireless chargers and, of course, power banks. But, whether you're in the office a few days a week, simply left your handset off the charger overnight, or you're jetting off on a weekend getaway, you'll soon find that your phone battery can drain far more than you expect when you're out and about. With wireless, USB, and USB-C charging all available, PowerCore gives you unprecedented choice over how you charge. You can even use all of them at once to charge 3 devices simultaneously. In terms of charging, this massive power bank can charge an iPhone 15 more than five times. It can charge a big Galaxy S23 Ultra's 5,000mAh battery three-and-a-half times. Best of all, it charges at the fastest speed available on most of your favorite phones (excluding Oppo/OnePlus's unusual SUPERVOOC battery). We'd recommend avoiding anything below 5,000mAh, though, as they'll barely recharge today's smartphones. Look for between 5,000 and 10,000mAh.
EnergyCell’s portable charger is as basic as power banks get, with just a micro-USB input, a USB-A output and no support for any fast-charging standards. What’s more, it’s slow. The USB-A output is specified as 10W, but in our tests we measured the output at between 7W and 9W depending on the phone. A 15-minute charge only raised the level on our test smartphone by 7%. 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. It's easy to get used to being a couple of feet away from a power cable or wireless charging pad on those days when you're working from home. It’s best to look at the main battery you’ll need to fuel up – we’re guessing it’s your phone – and work out how large of a power bank you need (of course, all phones have different battery sizes). The capacity is measured in milliamp hours (mAh) and the more you have, the more recharges you’ll get. 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.
FAQ
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. Congratulations on your new power bank! To ensure you get the most out of it, here's what you should do when you first buy one:
