The iWalk Magnetic Wireless Power Bank has a couple of features not found on other magnetic battery packs.

The most obvious is the finger ring, which is meant to mean safer holding but we prefer to grip our phone using a whole hand. But it does double-up as a kickstand for the iPhone so you can place it in a horizontal/landscape viewing position – horizontal feels more stable.

Even more useful is the LED battery-charge indicator that shows you exactly how much charge is in the power bank. This is way more helpful than the usual array of four tiny LEDs that most battery packs come with and especially more informative than Apple’s single Orange (not full) or Green (full) LED that lights up only when cable- connected to a power source.

The iWalk power bank also boasts a sizeable battery, with 2.2Wh (6000mAh) capacity. It recharged our test iPhone 13 Pro to 100% and then another 5% above that, so, in reality, a full charge with a little over for expected battery drain if left sitting in your bag for a few days. And it will charge a non-Pro 12 or 13 even further.

As such, it’s heavier and fatter (including the pull-out ring) than most other magnetic power banks tested here.

It can charge while magnetically clamped to the iPhone and also (but not simultaneously) by USB cable at an impressive 18W, although you’ll need a USB-C-to-Lightning cable for wired charging.

it comes with a USB-C-to-USB-C cable for charging the pack itself, and also a Magsticker to attach to non-MagSafe phones for the same battery-pack functionality.

Larger and weightier (2x the nearest rival) than alternatives, the Belkin Magnetic Portable Wireless Charger 10K is more of a wireless charging pad that can also be carried around as a power bank.

This isn’t a bad thing as many users will have a less frequent need of it as a power bank and will charge their phone at their bedside or on their desk while working.

But when you do need it, the Belkin 10K really delivers with a massive 38Wh (10,000mAh) battery capacity. Its 7.5W charging speed is also impressive.

It’s available in old-school black and white models.

Too bulky to attach to your iPhone and stay on while the phone is carried about, the Chargeasap Flash Pro Plus is not a proper battery pack like the others we have tested but is still portable and MagSafe compatible.

What it does offer is a massive battery capacity of 92.5Wh (25,000mAh), which should be enough to get you through a weekend festival.

It also can be recharged to go again, incredibly quickly. This power bank has graphene-composite technology inside, and so can be charged at much lower temperatures than lithium-polymer, which means it can also charge significantly faster.

Instead of taking three or four hours to recharge, with its 100W USB-C Power Delivery 3.0 inputs, in our tests this got from zero to 100% in 50 minutes, or to 80% in 45 mins.

Boasting five lithium-polymer graphene-composite battery cells that have been designed in partnership with Tesla and Panasonic, the Chargeasap Flash Pro Plus is priced accordingly, which isn’t surprising for gadgets based on the latest technologies. Graphene-composite batteries have a lifespan four times longer than lithium-polymer, rated for 2,000 cycles, which means they could keep going at full-pelt for five years or more.

It can charge a MagSafe iPhone at 15W and an Apple Watch at 5W, and has a large array of OLED percentage displays. With an array of outputs, it can charge up to six devices at the same time.

The RapidX Boosta Magnetic Wireless Charger scores around the same recharge power as other 5000mAh magnetic battery packs, and is similar in most other respects, too.

Wireless charging speed is 7.5W, or you can connect with a USB-C to Lightning cable (not included) for 10W wired charging. The Boosta comes with a white USB-C cable for charging the power pack itself.

While you can’t charge a phone simultaneously with a wired and the wireless connections, it does charge the phone and power bank together while plugged to power.

Where it wins by a mile is its color options, being available in seven shades. None exactly matches the iPhone but it’s a better than just black or white.

We’ve included a non-MagSafe portable power bank as an alternative to consider.

MagSafe technology helps wireless chargers lose less power through imprecise placement, but you don’t have that or any other wireless limitation when connecting a phone to a charger via cable.

The 38.48Wh (10,400mAh) battery is larger than any of the MagSafe chargers and so should offer well over 100% recharge potential for a fading iPhone (12, 13 or any Lightning iPhone for that matter). 

Its LCD screen spells out exactly how much power remains inside the bank, which is a lot more informative than the row of tiny LEDs you get with the other portable power banks, and much better than the Apple MagSafe Battery Pack that has just one LED that only lights up when connected to power.

As handy as the battery capacity and LED is, it’s still not as convenient or compact as a proper MagSafe portable battery charger that can be magnetically connected to your compatible iPhone.
