Show more Factors to consider when choosing an iPhone power bank Here are some factors I suggest you consider when choosing a power bank for your iPhone:Size: It's no good having a power bank if you're going to end up leaving it at home. Sure, if you're going off grid for a few days, you're going to need something big, but most people are looking for something to top up their phone during the day before going home, and for this a power bank with a 4,000mAh capacity is more than enough.Wired or wireless: If you don't want the hassle of having to carry a charge cable and a power bank, go for a unit that feature wireless MagSafe charging.Safety: I test every power bank for a number of safety issues, including checking for overheating in use and whether the case is robust enough to protect the internal batteries. I recommend sticking with name brands and avoiding dollar store power banks. Show more How we test iPhone power banks I chose these iPhone power banks through a combination of extensive research and using the products to charge everyday devices. I paid attention to:Customer reviews and ratings: I evaluated personal experiences and ratings of the included products to take note of strengths, weaknesses, and overall customer satisfaction with each battery pack.Pricing: I considered battery packs with a varied price range to ensure there is a product for everyone, with most battery packs costing between $20 and $100.Renowned brands: I selected battery packs manufactured by trusted and ZDNET-reviewed brands to ensure the recommended picks were of quality and standard.Capacity: Battery packs can differ in the amount of power (measured in milliamp hours or mAh) contained in the battery. I used a USB power meter to test the capacity of every power bank listed to ensure that it delivers what it says on the spec sheet.Overheating: I used a thermal camera to check for overheating, both when the power back was in use, and when it was being charged. Show more Does charging your battery from a power bank damage the battery on the iPhone? Some cheap power banks and chargers can harm your smartphone. Overall, though, power banks are safe and work using the same technology as a regular charger. We trust any of the picks above to be quality power banks that won't damage your iPhone's battery. Show more Are these power banks allowed on an airplane? According to the Transportation Security Administration (TSA), portable chargers or power banks containing a lithium-ion battery must be packed in a carry-on bag, rather than in checked baggage. Most airlines allow a power bank with a battery of up to 27,000mAh. Show more How much should you spend on a power bank? Those cheaper power banks work; however, in my experience, they don't offer the capacities that they claim and don't last nearly as long as a decent power bank from a reputable manufacturer, don't deliver the power stated, and can overheat in use.The phrase "you get what you pay for" applies to everything, including iPhone accessories. That's why it's better to spend more money to get something that'll enhance your phone's productivity and last. Show more Is a wireless power bank better? A wireless power bank can be very helpful, since you don't have to remember to bring any cords or cables with you. Just set your iPhone on the power bank and start charging.They're not ideal for use while you're actually traveling, however, since there isn't a way to secure your phone to the power bank. When flying or driving, your phone could slip off the charger without you noticing, leaving you with a dead or dying phone when you reach your destination. MagSafe power banks are good, but they're not infallible. Show more What size power bank do you need to charge an iPhone? It depends on how many recharges you want.
