MyCharge Superhero MagLock: MyCharge calls its line of magnetic power banks Superhero MagLock, implying that they’re real saviors. I was impressed by their design. Not only do the batteries, which come in various capacities and colors, have strong magnets and stick really well to the back of any MagSafe-enabled iPhone, but they have raised coils, which are supposed to help reduce heat levels while charging. It does seem to work. All the MagLock batteries charge Qi-enabled iPhones at 5 watts, although you can get faster charging if you go wired and use a USB-C-to-Lightning cable. I also liked how there’s a chime when the charging starts and your phone tells you how much juice is left in the battery pack
Anker 523 PowerCore Slim 10K PD: The Anker 523 PowerCore Slim 10K PD ($26) is impressively slim for a 10,000-mAh portable phone charger and has a fast 20-watt USB-C out charging port (it’s also a USB-C input to charge its battery), plus a 12-watt USB-A out port. While the Anker 313 PowerCore Slim 10K is cheaper, this offers fast USB-C outcharging, which makes spending the extra dough a big plus if you have a USB-C-to-Lightning cable.
Mophie Powerstation 10K Stand with MagSafe: Mophie’s Powerstation Wireless Stand with MagSafe isn’t cheap but is a versatile 10,000-mAh battery with both a stand and MagSafe charger built-in and also has a threaded tripod mount at the bottom. Since this is an official MagSafe charger, the battery does charge at 15 watts, making this among the fastest wireless external battery chargers out there and will also charge the AirPods 3 and AirPods Pro models with MagSafe. If you use a USB-C-to-Lightning cable (not included) with it, you can charge at 20-watt speeds. You can also charge two devices at the same time.
Anker PowerCore Fusion Portable Charger: This Anker model is effectively an oversized wall charger with a built-in 5,000-mAh battery. It’s got two standard USB charging ports for simultaneously juicing up your phone and a secondary gadget (or two phones). A little LED indicator on the side lets you check the charge level at the press of a button.
Anker PowerCore III 10K Portable Charger: The Anker PowerCore III 10K portable charger has fast USB-C out charging (18 watts) as well as a USB-A port and up to 10-watt wireless charging. It’s not magnetic, so your phone won’t stick to it but it will wirelessly charge any Qi-enabled devices.
Mophie Snap Plus Juice Pack Mini: Mophie’s magnetic power bank is similar to Anker’s but is slightly slimmer (it’s suitable for a 5,000-mAh battery) and doesn’t have an integrated flap that converts into a stand. It’s designed to adhere to the back of MagSafe-enabled iPhone or MagSafe cases, it comes with a “snap adapter” ring to stick onto the back of Android devices so they’ll be magnet-friendly.
