To be clear, nearly all of the models below will work with any recent iPhone -- you'll just need to make sure you have a charging cable that matches the ports on both sides (power bank and phone). On the wireless side, all Qi chargers will work with iPhones since the iPhone 8 and iPhone X lines, but chargers officially certified as MagSafe compliant will charge the phones faster and offer better feedback on the screen. Apple has yet to clarify if the forthcoming Qi2 chargers offer any additional benefits on the iPhone 15 line.

While we wait for newer models, here are our current picks. While this list is geared toward iPhones, any portable battery pack on the list with a USB-C or USB-A out ports will work perfectly well for charging an Android smartphone (or any other portable gadget), so long as you provide a compatible smartphone cable. Wireless (or inductive) charging should also work for Android phones that are so configured. 

So what's the best portable charger for juicing up your iPhone on the go? Here are our top picks, all of which I've tested and reviewed. I'll update this list as soon as the new iPhones and charger details have been confirmed.
