- Magnetic mounting is described as tool-free and detachable for moving the unit between radiators.

## Pros

## Before you buy

- The listing gives no measured evidence for its claimed faster warming, under-25dB noise level or potential savings of up to 20%, so treat these as manufacturer claims rather than expected outcomes.
- Listing details are inconsistent or unconfirmed: the title says 3 fans while the feature text also describes a triple-fan design, and the battery, USB-C charging, runtime, noise and thermostat claims appear in promotional text but are not all separately specified in the technical details. The listing also describes both a maximum temperature setting and heat output without explaining how these relate to a radiator-mounted fan. Confirm the operating details and radiator fit before buying.

## A good fit for

- People wanting to circulate heat from an existing radiator in a small or medium room.
- Buyers who value cordless placement and a magnetic radiator attachment.
- Households looking for a radiator accessory rather than a standalone electric heater.

## Less suited to

- Anyone needing an independent source of room heat, since this product is described as boosting heat from an existing radiator.
- Buyers who need independently substantiated noise, energy-saving or heating-performance figures.

## Customer feedback

The supplied evidence contains aggregate ratings only, with a largely favourable distribution among a small number of ratings. It does not include customer comments, so it cannot establish which features people liked or any particular concern. For a radiator-booster purchase, check fit, operating time and performance expectations against the listing claims rather than treating the rating as confirmation of them.

## Frequently asked questions

### Does this work as a standalone heater?
The listing describes it as a fan booster that circulates heat from an existing radiator. It does not describe an independent heat source.
### How long is the claimed cordless runtime?
The feature text claims 6 to 16 hours on a charge from its 5200mAh battery. This runtime is a listing claim, and the supplied technical details do not specify how it varies by speed or conditions.
### How is the fan mounted and charged?
The listing claims magnetic, detachable mounting and USB-C charging. Check that the mounting suits your radiator before buying.
### Are the stated energy savings guaranteed?
No. The listing advertises savings of up to 20%, but does not provide supporting test details or guarantee that result.
