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. There are plenty of combination power bank and some other device, but the Tylt Bottle 2 actually makes sense because we're usually carrying an insulated water bottle anyway, so we might as well screw a battery onto the bottom. With a 5,700mAh capacity, the Tylt Bottle 2 is just enough to get us through a very busy day, or keep the phone powered while we play games at the cafe. 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. Baseus 10,000mAh magnetic portable charger specs : Capacity: 10,000mAh/18.5Wh | Charging Port:Wireless Charging (7.5W and 15W) + USB-C (20W PD) | Power button: Yes Basically, you’re trying to balance four factors: size, speed, capacity and price. The rules are simple enough: the less you spend, the lower the capacity and the slower the power bank will charge.

A strong wireless charger that supplies your phone with up to two recharges and can recharge two devices simultaneously. Keep in mind that MagSafe chargers and MagSafe- compatible chargers aren't the same. A MagSafe charger supports a maximum output of 15W and has a built-in magnetometer and compass to prevent interference if you use your iPhone while charging. Chargers that are only MagSafe-compatible rely on the Qi charging standard, max out at charging speeds of 7.5W, and don't feature anti-interference features. Those compromises could be a deal breaker for some, but you might not care in light of their lower cost. 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. Step up from the budget power banks to the mighty Juice Powerbank Max and you get a much more capable mobile charger, with a 20,000mAh capacity and a 20W USB PD output over USB-C. We measured the USB-A output at nearly 15W in our tests, which recharged our smartphone by 18% in 15 minutes. With USB-C, that output rose to just over 19W, which was good for a 22% recharge in 15 minutes. That’s not bad at all for an affordable power bank, and we also found it usable for charging tablets and even a Chromebook laptop, albeit at a slower-than-usual speed. 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.As such, it’s heavier and fatter (including the pull-out ring) than most other magnetic power banks tested here. 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.

We love that the Anker 622 comes with its own built-in fold-out stand, which with MagSafe’s pulling power will hold your iPhone securely in either portrait/vertical or landscape/horizontal mode. The Belkin BoostCharge 5K, reviewed above, has a tougher metal pull-out stand, and also offer another 10% of charge on the better-looking Anker 622. It’s MagSafe compatible rather than certified, so charges at 7.5W instead of 15W, but its 10000mAh battery capacity is significantly greater. 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. 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?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 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. Courant Mag:2 Essentials / Classics: Courant’s same elevated formula but this time in a 2-in-1 charger for your phone and earbuds. If you’re the type that obsesses over mid-century modern stylings like hairpin legs and Eames chairs, here’s your (non-MagSafe) magnetic charger. It’s even sold at the Herman Miller store — need I say more?

Aside from that, this is a high-capacity magnetic power bank that charged our test iPhone 13 Pro 1.5 times. One advantage of this shift to USB-C is that power banks now support USB PD for faster charging. This means your power bank will often recharge faster when connected to a suitable fast charger, at anywhere from 20W to 60W. At those speeds, even a high-capacity charger can recharge fully in three to four hours. Capacity: Decide what battery capacity you’ll want. The higher the capacity, the more charges it can hold. With that in mind, the higher you go in capacity, the higher the price and the bigger the charger will be. Capacity is measured in milliampere-hours or mAH. 5,000mAH is standard and will recharge your phone once completely, on average.

Package Includes:

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. Charging Speed: The higher the watts your power bank can deliver, the faster your phone will charge. A five-watt capacity is pretty standard, but some can go as high as 15. 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.

This power bank is built for the iPhone 15 family—with its neat integrated USB-C cable—but it works as well as any other wireless power bank tested here with the other MagSafe iPhones. Connect the cable to a power source: Plug the other end of the cable into a USB wall charger or a USB port on a computer. Make sure that the power source can supply the necessary amperage and voltage to the power bank. 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. Most power banks now use a USB-C port to recharge, although some models will have a micro-USB port as well to ensure compatibility with older chargers. Don’t worry if you don’t have the required cable, as one will usually be provided in the box. 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.

Fast Charge

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. The Newdery Battery Case scored 96% in our test, showing that it will supply very close to a 100% recharge—better than any MagSafe power bank that we have tested so far. Most companies advertise how many times their products can recharge popular phones, but if you want to calculate that number for yourself, RAVPower has a useful guide that can give you an estimate. The Anker battery charges wirelessly at 7.5W–faster than Apple’s 5W charge, although the Apple battery can use the wireless Qi and cabled USB-C power simultaneously to speed charging at up to 15W.
