UGREEN MagFlow Air Magnetic Power Banks Reviewed

UGREEN have sent us two of their new MagFlow Air magnetic power banks to test: the 10,000mAh model and the ultra slim 5,000mAh model.

We previously reviewed UGREEN’s Qi2 25 watt MagFlow wireless charging devices, including the 10,000mAh MagFlow Magnetic Power Bank and the MagFlow 2-in-1 Wireless Charger, both of which impressed us with their design, build quality and everyday usefulness.

This time, the focus is on portability. The MagFlow Air range is designed to be thinner, lighter and easier to carry, while still offering magnetic wireless charging for compatible phones.

The two models are very similar in concept, but they are aimed at slightly different users. The 10,000mAh version is the one to choose if you want more battery capacity and extra flexibility, while the 5,000mAh version is the more pocketable option for quick top-ups during the day.

UGREEN MagFlow Air Magnetic Power Bank 10,000mAh

The larger of the two models is the UGREEN MagFlow Air Magnetic Power Bank 10,000mAh. Despite the higher capacity, UGREEN has managed to keep the design relatively slim at 13.9mm thick.

That is the main appeal here. A 10,000mAh power bank is usually something you throw into a bag rather than keep attached to your phone, but this model is designed to be slim enough to use while still attached magnetically to the back of your device. So while it has the “larger” capacity, it is by no means a large device in hand and is considerably smaller than the previous model we linked to above (see comparison photos below).

The 10,000mAh version supports Qi2 15W wireless charging, so for compatible iPhones and other Qi2 devices, you can attach it magnetically and start charging without needing to line anything up manually.

It also includes an integrated USB-C cable, which is a very useful addition. This cable supports up to 30W fast charging and can be used to charge your phone or recharge the power bank itself. There is also an additional USB-C port, meaning the 10,000mAh model can charge up to three devices at once through wireless charging, the built-in cable and the USB-C port.

Like all of these recent accessories from UGREEN, there is a real sense of quality to the fit and finish of the power bank. The materials used feel high-quality, and the design is sleek.

The body uses an aluminium alloy design, which gives it a more premium look and feel, while also helping with heat dissipation. UGREEN also includes multi-layer protection against issues such as overheating, overvoltage and short circuits.

I am a big fan of the built-in cable. It means you don’t need a separate cable to charge the power bank, and you can also use it to charge a device that doesn’t have magnetic charging. It feels robust, and it secures tightly in the device, so you can use this to hook the powerbank onto something like a backpack if needed.

The 10,000mAh model will provide enough juice to charge an iPhone 17 Pro Max around 1 and a half times, and you can recharge the powerbank in around two hours using a 30W input.

UGREEN MagFlow Air Magnetic Power Bank 5,000mAh

The slimmer model is the UGREEN MagFlow Air Magnetic Power Bank 5,000mAh. This is the one designed for maximum portability.

At just 8.6mm thick and 127g, it is much lighter and thinner than the 10,000mAh version. It is the model that makes most sense if you want something you can keep in your pocket and use for quick top-ups without adding too much bulk to your phone.

Like the larger model, it supports Qi2 15W magnetic wireless charging. UGREEN says the magnets can provide around 8kg of holding force, which should help keep the power bank securely attached while charging.

In day-to-day use, those magnets attach securely, and there is no sense of the power bank detaching by accident. The clever design means the powerbank fits perfectly on the back of an iPhone 17 Pro Max or iPhone Air.

With the power bank attached to my iPhone 17 Pro Max, it was still really easy to hold the phone, and the extra weight doesn’t unbalance the phone in your hand. Nor does it interfere with using any of the phone’s functions, such as taking photos.

It is hard to see batteries using this technology getting much smaller or lighter, so this is about as good as it is going to get when it comes to ultra-slim and mobile power banks.

The 5,000mAh version also supports wired USB-C charging, with 20W input and output. It has one USB-C port rather than the built-in cable and extra charging flexibility of the larger model.

That makes it a simpler device, but that simplicity is part of the appeal. It is smaller, lighter and less obtrusive, and for many people, that will matter more than having the extra capacity.

The 5,000mAh model uses a soft-touch silicone finish, which should help protect the back of your phone from scratches while attached.

I mainly used this power bank to top up my phone during a heavy day of usage. Even though it has less capacity, I found myself grabbing this powerbank more than the larger one, as you can easily fit it with the phone in a pocket, and you barely notice the extra weight. When I knew I would need to charge earbuds or my watch too when on the road, the extra capacity and functionality of the larger model were ideal.

Design and Portability

Both units support Qi2 15W wireless charging speeds so the real difference is capacity, size and how you are likely to use them.

The 10,000mAh model is the more versatile travel option. It gives you more battery capacity, a built-in USB-C cable, faster 30W wired charging and the ability to charge more devices at once.

The 5,000mAh model is the more discreet everyday option. It is much slimmer and lighter, and is the one you are more likely to leave attached to your phone while walking around, travelling or using your phone normally.

For day-to-day use, this distinction matters. A power bank can have impressive capacity, but if it is too bulky to carry, you will leave it at home. The 5,000mAh model is the one that feels most like a “just in case” device, while the 10,000mAh version feels more like something you would bring when you know you will be away from a charger for longer.

Comparison with the Previous MagFlow Power Bank

The previous UGREEN MagFlow Magnetic Power Bank we reviewed suppors 25W wireless charging and also has a useful built-in USB-C cable. It was an excellent all-round device and felt like one of the stronger UGREEN products we had tested to date.

The new MagFlow Air models are slightly different. They step down to Qi2 15W wireless charging, but the focus is clearly on making the devices thinner, lighter and easier to carry.

In most cases, the slimmer models will win out, even if they are slightly slower charging. There is a noticeable difference in charging speeds between the 15W and 25W chargers, but the extra portability of the slimmer models is often more important for most use cases.

For most users, though, it will come down to how they actually use a power bank. If you want the fastest wireless charging and do not mind a slightly chunkier device, the previous 25W MagFlow model still has obvious appeal. If you want something slimmer and more pocketable, the MagFlow Air models make more sense.

Conclusion

UGREEN’s MagFlow Air Magnetic Power Banks are another strong addition to the company’s growing range of charging accessories. They take the convenience of magnetic wireless charging and package it into slimmer, more portable designs.

The 10,000mAh version is the more capable and versatile of the two. It has more capacity, faster wired charging, a built-in cable and the ability to charge multiple devices at once. It is the better choice for travel, long days out and heavier phone users.

The 5,000mAh version is the more elegant everyday option. It is thinner, lighter and easier to carry, making it ideal for quick top-ups and casual day-to-day use.

Overall, both models continue UGREEN’s recent run of well-designed, practical and good-value charging products. The best choice depends on whether you prioritise capacity or portability, but both are easy to recommend for iPhone users and anyone with a compatible Qi2 magnetic charging device.
