There are a lot of “MagSafe” magnetic wireless battery packs on the market. Some are nice, some are numerous 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 mild, it is trendy, and it is cool — in each sense of the phrase. And it is successfully changed the solid-state battery pack I have been utilizing for months. This is why.

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 when you’re on the transfer. The capability is such that it will not draw consideration at airports, and the CCC brand means that it’s going to even make it previous the stringent safety at Chinese language airports.

The unit has a premium look and feels good within the hand, because of its glass and aluminum building. 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 material.

Skinny, mild, and funky

First off, it is skinny. Actually, 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 also 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 every thing else, there is a 20W USB-C port on the underside. And excellent news for these with a couple of 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 costs, which is ideal for in a single day charging. The unit helps all in style charging protocols, and it has the same old built-in security options. 

The Q.Magazine X can also be cool throughout use, surprisingly so for a 15W MagSafe energy financial institution, which might generally really feel like hand heaters. This machine solely ever obtained 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 sizzling 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, but it surely’s so nicely 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 strategy to discover out. 

Time to crack it open

It was time to get the spudger out, be harmful, and look inside (I do know I should not be utilizing a steel spudger close to a stay lithium-ion battery, however I have been doing this for years). I regretted having to do that process, but it surely needed to be performed. 

I discovered a number of issues.

First, sure, the battery has a graphene coating. Graphene appears to be like like black paint, but it surely’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 nicely constructed. It took some moving into, and there is ample sealant, adhesive, and thermal silicone preserving it collectively. 

Additionally, Momax hasn’t skimped on the elements you could’t see. The parts used are top-notch, and it has been put collectively nicely.  

ZDNET’s shopping for recommendation

I’ve examined numerous 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 obtainable), it is a steal. You must particularly think about one when you typically end up in heated environments that may put batteries at risk.

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