Charge it Fully: Plug in your power bank and let it charge fully before using it. This ensures that it's ready to provide a reliable power source when you need it. High Capacity Hero: The super huge 40,000mAh cell capacity is large enough to fully charge an iPhone 13 over 8 times, a Samsung Galaxy S22 Ultra over 6 times, and a 2020 MacBook Air over 2 times. Meanwhile, a 10,000mAh battery can give today’s flagships two full charges. A 20,000mAh battery can charge a flagship four times, or two phones two times. Some power banks have enough juice to power laptops. Of course, a higher capacity often translates to a heavier, larger, and more expensive battery. Anker 313 Power Bank (PowerCore 10K)- Anker’s 313 10000 mAh power bank is a wonderful travel companion. With an astonishingly sleek and lightweight design, it is equipped with Anker’s world-renowned PowerIQ technology along with MultiProtect Safety System, which effectively delivers a power boost and lets you rest assured of safety anywhere you go. Anker makes affordable products. They may not be the absolute cheapest on the market, but Anker's chargers are generally competitively priced.

You can always buy an extra cable to charge up your power bank, but we just find it useful to only have one type of cable, so if your phone supports USB-C charging you'll likely want to find a power bank that supports the same. You need a lot of power: Thankfully, the battery on the Tylt Bottle 2 isn't so big it adds too much weight, but that also means it isn't powerful enough for multiple charges. The number in the title of the power bank usually refers to the capacity of it, so the PowerCore 20000 for example features a 20,000mAh battery. Features 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. 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.

Customer Reviews

Yes, cheap power banks are worth it if you seek a budget solution. You can get a decent-quality power bank already for just a few dollars, and they'll keep your phone charged once a day. However, the portable charger mAh difference is very noticeable compared to the high-quality ones, especially if you're looking for a power bank that lasts more than a day. Should I get 10000mAh or 20000mAh power bank? This power bank holds a massive amount of charge that it transfers to your devices at lightning speed; it can take most laptops from 0 to full charge in about 2 hours. It can completely charge a MacBook Air 1.2 times and can charge most phones at least 5 times over. You need fast power: This is a very slow charger, whether wired or wireless, so it's better for casual charging while you sip your water and read a book. 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.

High Capacity Hero: The super huge 40,000mAh cell capacity provides 8.8 charges for iPhone 13, 6.8 charges for Samsung S22 Ultra, and 2.3 charges for MacBook Air 2020. Power Delivery is a newer protocol in which two compatible devices negotiate on the fastest charging option available based on the charger, cable, and circuitry. It also allows for power to flow both ways. Generally speaking, you charge the battery itself via micro USB or USB-C (input). Some batteries charge faster than others and USB-C charges much faster than micro USB. 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.

The World's No. 1 Mobile Charging Brand*

Look for a power bank with safety features such as overcharge and short circuit protection. All Anker power banks are going to have these basic safety features as part of their MultiProtect safety system. Anker has just released its largest portable charger with no AC outlets... Take a look at 347 PowerCore 40K! USB-C charging gives you the power you need to charge up your iPhone 13 to 50% in just 28 minutes—that’s up to 3 times faster than your old 5W charger.

As a general rule, smaller sizes like 4,000 or 5,000mAh may not be enough for more than one recharge of most handsets, while 10,000mAh is a great midrange size that’ll deliver a couple of recharges. You’ll have noticed that we list the battery capacity in milliamp hours (mAh) throughout this roundup, and it’s worth using this as a guide to the charger size you’ll need. The bigger the number is, the more capacity it has. Of course, phones all have different batteries too. 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. It's no exaggeration that modern-day gadgets and appliances have become essential in our daily lives. Hence, it's vital that they're never without a power source, and a good power station can help with this.Capacity:Think of capacity as the energy reservoir of your power bank. The higher the mAh (milliampere-hour), the more power it can store. So, choose a power bank with a capacity that suits your charging needs and can juice up multiple devices. 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). 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.

You can buy the Tylt Bottle with just a power bank attached, but our review sample from AT&T had the full wireless charging treatment. It's easy to set up a phone to charge while studying, working out, or working away from home: all places we take a water bottle and need a full phone battery. Laptop computers draw serious power– a lot more than your phone or other small devices– and so if you’re planning to travel with a laptop, you want to make sure that your power bank can support a power-hungry device. 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.Designed to provide optimized charging to low-power devices such as earphones, Bluetooth speakers, and other accessories. 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). To conclude, it's important to remember that power banks and portable chargers are basically just the same. We hope we've been able to clear up the confusion around these two terms and helped you to find the perfectly suited power bank for your needs. FAQ 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. One of the few power banks capable of delivering 140-watt power, the Anker 737 is a very powerful power bank. It weighs in at nearly a pound and a half and can deliver the power you need to keep working through a layover, power outage, or any other situation where you need a lot of power right away.
