PORTENTUM Qi2.2 25W magnetic car phone holder with active cooling

The zinc body measures 6.1 x 1.9 x 8.5 centimetres and comes in silver. This vent-mounted holder combines magnetic positioning with wireless charging. Could it suit a car set-up where the phone is used for navigation and needs to stay visible? A 360° adjustment lets you set the viewing angle.

Why it makes sense

The useful distinction here is that the PORTENTUM is both a phone mount and a wireless charger, rather than a basic holder that leaves charging to a separate cable and adapter. It has Qi2.2 certification (version 2.2.1, Qi ID 25160) and supports MPP wireless output up to 25W on compatible devices. The built-in fan is intended to help dissipate heat during charging, which may be helpful on longer drives or during continuous use, it is not a substitute for checking that your phone supports the stated charging rate.

The mount attaches to an air vent and uses a rotating ball joint to adjust the phone’s position. Its zinc-alloy body and 16 N52 magnets are designed to hold the phone in place, with a maximum stated weight capacity of 900 grams. That combination favours drivers who want a fixed, adjustable charging point, rather than a simpler mount with no charging or a set-up built around a separate cable.

The essentials

Charging speed depends on the phone. The product details state up to 25W for iPhone 16 and 17 models and other Qi2.2 MPP-compatible devices, and up to 15W for iPhone 12 to 15 models with MagSafe. Other Qi phones, including older iPhone models, can use the included magnetic ring for alignment, but the ring is specifically for phones or cases without MagSafe. The details do not give a charging rate for every listed compatible phone, so the maximum output should not be assumed across the whole list.

A USB-C to USB-C cable rated at 60W is included, along with the magnetic ring, vent mount and user manual. The cable rating is not the same as the holder’s wireless output: the stated maximum is up to 25W, and only for compatible devices. For a navigation journey, the intended routine is straightforward: attach the holder to the vent, position the phone magnetically, then adjust the angle for a clear view.

Getting the most from it

For reliable alignment, use MagSafe on a compatible phone or case, or fit the supplied ring where required. The adjustable joint can help direct the screen towards the driver, but the product details do not specify which vent designs it fits, so suitability will depend on the car’s vent. The holder is not water resistant, making it a poor match for a location where it may be exposed to moisture.

Before you decide

Does it charge every compatible phone at 25W? No. Up to 25W is stated for compatible Qi2.2 MPP devices, the listed iPhone 12 to 15 models with MagSafe are stated at up to 15W. Other listed devices may have different charging rates.

Is the magnetic ring needed? It is included for phones or cases without MagSafe that need magnetic alignment. MagSafe-compatible phones and cases can attach magnetically without it.

Can the phone be repositioned? Yes. A rotating ball joint provides 360° adjustment, and the mount attaches to an air vent.

When it makes sense

It makes sense if you want a vent-mounted holder with wireless charging, magnetic attachment and an adjustable viewing angle, especially for regular navigation. Better avoided if you need a water-resistant mount or expect every phone on the compatibility list to reach the same charging speed. The key choice is whether your phone supports the stated output and whether an air-vent mount suits your car.
