There are various “MagSafe” magnetic wireless battery packs on the market. Some are nice, some are varied grades of dismal. And generally, gadgets are head and shoulders above the remaining. These packs are well-built, utilizing high quality parts, and assembled with care.

The Momax Q.Mag X is one such energy financial institution. It is skinny, it is gentle, it is fashionable, and it is cool — in each sense of the phrase.

It is a handsome energy financial institution

The Q.Magazine X is a 5,000 mAh/19.35 Wh energy financial institution that magnetically clamps to your iPhone to cost it up whilst you’re on the transfer. The capability is such that it will not draw consideration at airports, and the CCC emblem means that it’ll even make it previous the stringent safety at Chinese language airports.

The unit has a premium look and feels good within the hand, due to its glass and aluminum development. It isn’t probably the most strong energy financial institution in the marketplace — for that, you want one thing just like the Nitecore NW5000 or the Dark Energy Poseidon Nano — but when attractiveness are what you are after, that is the machine for you.

However there’s extra to the Q.Magazine X than attractiveness. And to maintain it wanting good, the financial institution even comes with a microfiber sprucing fabric.

Skinny, gentle, and funky

First off, it is skinny. The truth is, it is spookily skinny, at solely 8.3 mm/0.33 inches. That is the thickness of a pencil, and it is solely fractionally thicker than the thinnest level on an iPhone 17, which is 7.95 mm/0.31 inches thick.

The financial institution can be very light-weight, at solely 125 g/4.4 oz, making it solely 5 g/0.18 oz heavier than the carbon fiber-clad Nitecore NW5000.

On the entrance is a 15W Qi2-compatible wi-fi charger that works with iPhones ranging from the 12 to 17 series, AirPods with the wi-fi charging case, and Android handsets with wi-fi charging. For all the pieces else, there is a 20W USB-C port on the underside. And excellent news for these with multiple machine — the facility financial institution helps simultaneous wi-fi and wired charging.

It additionally helps pass-through charging, so you’ll be able to cost a wi-fi machine as the facility financial institution fees, which is ideal for in a single day charging. The unit helps all well-liked charging protocols, and it has the standard built-in security options.

The Q.Magazine X can be cool throughout use, surprisingly so for a 15W MagSafe energy financial institution, which may generally really feel like hand heaters. This machine solely ever bought barely heat at most. The Amazon itemizing talked about graphene warmth dissipation, which would not shock me within the least, as there have been no scorching spots on the unit both whereas charging or being charged (I am going to get again to this space in a bit).

I actually just like the Q.Magazine X. I do know it is only a energy financial institution, nevertheless it’s so properly made. The machine completely combines magnificence and performance. I’ve loved utilizing it for the previous few weeks when out and about.

Which is why the following bit broke my coronary heart. Sure, I wanted to see if the facility financial institution used graphene for cooling, and there was just one option to discover out.

Time to crack it open

It was time to get the spudger outbe damaging, and look inside (I do know I should not be utilizing a steel spudger close to a reside lithium-ion battery, however I have been doing this for years). I regretted having to do that activity, nevertheless it needed to be finished.

I realized just a few issues.

First, sure, the battery has a graphene coating. Graphene seems like black paint, nevertheless it’s a type of carbon with wonderful thermal conductivity and infrared emissivity, so it is sprayed onto metals, plastics, and electronics to unfold and dissipate warmth.

I additionally came upon that the unit could be very properly constructed. It took some stepping into, and there is ample sealant, adhesive, and thermal silicone preserving it collectively.

Additionally, Momax hasn’t skimped on the components that you would be able to’t see. The parts used are top-notch, and it has been put collectively properly.

ZDNET’s shopping for recommendation

I’ve examined lots of wi-fi energy banks, however the Momax Q.Mag X is a standout, each exterior and in. And for just below $30 (the worth varies relying on the offers out there), it is a steal. You need to particularly contemplate one in case you typically end up in heated environments that may put batteries in peril.

In case you want extra energy, Momax have a scaled-up 10,000 mAh version. Similar high quality, extra capability, for lower than $10 extra.
