The best iPhone power banks give you enough portable power to keep your phone running until you can plug it in. Here’s more detailed information if you’re trying to decide which power bank is best for you as they all vary in power source, price and even port availability.

Here are some factors I recommend you consider when choosing a power bank for your iPhone:

• Size: There is no point in having a power bank if you plan to leave it at home. Sure, if you’re going to be off the grid for a few days you’ll need something big, but most people are looking for something to top up their phone during the day before heading home and for that matter. Hey, a power bank with a capacity of 4,000mAh is more than enough.
• Wired or wireless: If you don’t want the hassle of carrying a charging cable and power bank, choose a device with MagSafe wireless charging.
• Safety: I test every power bank for a number of safety issues, including checking for overheating during use and whether the case is sturdy enough to protect the battery inside. I recommend sticking with name brands and avoiding power banks that cost pennies on the dollar.

I chose these iPhone power banks through a combination of extensive research and using the products to charge my devices on a daily basis. I pay attention to:

• Customer reviews and ratings: I evaluated personal experiences and ratings of included products to document the strengths, weaknesses, and overall customer satisfaction of each battery pack.
• Price: I reviewed battery packs at various price points to make sure there was something for everyone, with most battery packs costing between $20 and $100.
  
• Famous brand: I chose battery packs manufactured by trusted brands and evaluated by ZDNET to ensure the recommended options were of quality and standard.
• Capacity: Battery packs may vary in the amount of power (measured in milliamp hours or mAh) contained in the battery. I use One USB power meter to check the capacity of every power bank listed to make sure it delivers what it says on the spec sheet.
• Overheat: I use One thermal camera to check for overheating, both while on mains and while charging.

Some cheap power banks and chargers can harm your smartphone. However, in general, power banks are safe and operate using the same technology as regular chargers. We believe any of the above options are quality power banks that won’t damage your iPhone’s battery.

According to Transportation Security Administration (TSA)Portable chargers or power banks containing lithium-ion batteries must be packed in carry-on baggage, rather than in checked baggage. Most airlines allow power banks with batteries up to 27,000mAh.

Those cheaper power banks still work; However, in my experience, they do not provide the capacity they claim and do not last as long as a good power bank from a reputable manufacturer, do not deliver the power as stated, and have may overheat during use.

The phrase “you get what you pay for” applies to everything, including iPhone accessories. That’s why you should spend more money to buy something that will enhance the performance and longevity of your phone.

Wireless power banks can be very useful as you don’t need to remember to carry any wires or cables with you. Just set yours iPhone on the power bank and start charging.

However, they are not ideal for use when you are actually traveling because there is no way to protect your phone with a power bank. When flying or driving, your phone could slip off the charger without you even realizing it, leaving your phone broken or dead by the time you arrive at your destination. MagSafe power banks are great but not infallible.

It depends on how many recharges you want. A 5,000mAh power bank will give you about twice the charge of a standard iPhone, and a little less for larger iPhones.
