Best MagSafe Portable Battery Packs and Power Banks for iPhone 12, 13, 14, and 15

It appears that the text above is from an article discussing battery packs for the Apple iPhone, including magnetic wireless battery packs and battery cases. The article evaluates products like the HyperJuice Magnetic Wireless Battery Pack and the Newdery Battery Case, comparing features, prices, and performance in testing for the iPhone 12, 13, 14, and 15 models.

In the case of the HyperJuice battery pack, despite its 12W input and the ability to charge two devices simultaneously via wireless and USB-C connectivity, it only managed to achieve a 74% score in the charging tests. The high shipping charges internationally also make it a less attractive option for consumers outside the US.

On the other hand, the Newdery Battery Case provides not only extra battery life but also offers full protection for the iPhone. The case performed admirably in tests, with the 5000mAh model reaching around 95%, and the 10K battery cases achieving a 168% charge. It’s noted to be an affordable alternative to a MagSafe case and MagSafe battery pack.

The article further explains how the author conducted testing using iPhone 13 Pro and iPhone 15 Pro models. The methodology involved draining an iPhone Pro to 10% and then charging it with the battery packs to measure the percentage charged. The test does not simulate real-world use but provides a standard comparison metric.

Additionally, the article discusses why comparing watt-hours (Wh) is more appropriate than milliamp-hours (mAh) when assessing battery capacities for providing power to devices. This is because mAh only measures electrical charge and does not account for voltage, which is critical in determining the power a battery can actually provide.

The article’s author, Simon Jary, provides a detailed analysis encompassing technical specifications, efficiency, and the practicality of different battery charging solutions for iPhone users. It references additional reading for those interested in in-depth discussions about iPhone battery capacities and comparison of mAh and Wh ratings.

The context suggests that this is a thorough review intended for users looking to understand the best battery pack options for their iPhones and how these products stack up against each other
