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. 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. There are plenty of other power bank makers around, and most of them have not caught up to the faster charging speeds available on the iPhone 15 family, let along even faster Android phones. Except for unique form factors or serious bargains, we stayed away from recommending power banks from reputable makers if they couldn't charge at 2023 speeds. That's a bit of a jump up for the Anker product, but generally it's worth paying that to have a power bank from a more trusted brand. This wireless charger does not feature MagSafe-style magnetic alignment, and therefore is not able to charge the iPhone 12 series magnetically.

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. 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. 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. 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.

What is the cost of a power bank?

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. The best power banks you can buy in 2023 1. EnergyCell Portable Charger 5000mAh: Best cheap power bank 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.

Qi-certification offers flawless wireless charging with compatible devices, while our exclusive PowerIQ 3.0 technology ensures optimized charging to virtually any mobile device including phones, tablets, and more. Quality Throughout:Built adventure-tier touch with superior durability and scratch resistance, Anker 313 Power Bank (PowerCore 10K) is premium both inside and out. 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. 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.

Solar 42800mAh Power Bank

The next question is how you want to charge your device. You can find a power bank that charges your phone (or even your Apple Watch) wirelessly. These will usually charge slower, but they can be very convenient if you want to leave wires at home. 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?

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. 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. 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. 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. Next, we rated and scored all the extra features and functions that make these chargers more user-friendly and convenient, which accounts for 20% of the overall score for each product. Regrettably, the bare-bones nature of the Anker PowerCore 10000 didn't get many accolades in this metric.Surge protection, short circuit prevention, and more advanced safety features keep you and your devices safe. Place your phone on the center of the wireless pad to ensure stable charging. If your phone does not show as charging, adjust the position of your phone.
