![]() But at the same time, you probably don’t need to worry too much about precise numbers. In short, the numbers that you see - generally mAh for battery packs - don’t always tell the whole story. These values allows you to compare Apple’s product with other devices. Unfortunately, Apple doesn’t specify either mAh or Wh for their battery pack, so you have to search to find the numbers: 1,460 mAh and 11.13 Wh. ![]() This latter figure is more important, because they take into account the voltage at which the battery pack can charge a device. Portable battery packs are rated in mAh, but also in Wh, or watt hours. This makes sense given the relatively small size of the pack compared to these phones. This means that this battery pack will not provide a full charge to an iPhone. Apple sells a MagSafe Battery Pack, and they say that it will provide, for example, “Up to 60% additional charge” with the iPhone 14, and between 40% to 70% for other models, depending on their internal battery capacity. Some battery packs provide the equivalent of several days’ charge for an iPhone, while others are more limited. (*Depending on the battery pack, it may have USB Type A or USB-C ports, or both.) You can also use this type of battery pack to charge non-Apple devices, as long as you have the appropriate cable. You can attach a USB* to Lightning cable to charge an iPhone or AirPods, or a USB* to USB-C cable to charge most Beats headphones. They generally have one or more USB ports so you can plug devices into them, and many have a separate USB port to charge them. Portable battery packs are pocket-sized devices that contain large lithium-ion (Li-ion) batteries. The mAh capacity of a battery offers minimal guidance about how long it lasts, but can help you determine what sort of portable battery pack you need to partially or fully charge them. MacRumors found battery capacity information in a Chinese regulatory database, confirming these test results. ![]() DXOMARK tested the iPhone 14 Pro and found that its battery’s capacity was 3,200 mAh. Apple doesn’t specify the capacity of its batteries, but third parties test Apple devices and publish their results. The second way battery life is measured is by the capacity of the battery in milliampere/hours, or mAh. The tasks you perform are different from those in Apple’s test suite, and you may have your iPhone brighter than they did in their test, because, well, you need to see what’s on the screen. You probably find that your iPhone’s battery doesn’t last 20 hours. For example, the basic iPhone 14 offers video playback of “up to 20 hours,” and audio playback of “up to 80 hours.” These vague estimates of battery life are based on very specific settings on the device, with certain features activated, brightness at a certain level, and more. The first is the number of hours that a device can work, according to the manufacturer’s specifications. Non-MagSafe options, including for MacBooks and iPadsīattery life for mobile devices is measured in two ways.Battery packs to charge your Apple devices on the go.In this article, we’ll take a look at portable battery packs that you can use to charge all your Apple mobile devices: your iPhone, iPad, Apple Watch, AirPods, Beats headphones, and even your MacBook. And when you’re on the road, it’s especially important to ensure that your devices won’t run out of juice, because you may not be able to plug them into power outlets anytime soon. ![]() When their batteries run out, you either need to charge them or you can no longer use them. Power is essential for your mobile devices. How To How to keep all your Apple devices charged on the go
