Froza review (2026): five watts, and what they can do
Quick verdict
Froza review in one minute: Froza is the only cooler in our line-up that mounts on a wall without a single drill hole, which makes it the default pick for renters (7.5/10). The brand publishes its rated power — 5 V, 1.0 A, about five watts — which almost nothing else in this category does, and which is also what makes the affiliate checkout’s “35 °C to 17 °C” claim impossible. Buy it for flexible placement and near-zero running cost; skip it if you expect room-wide air conditioning.

Who Froza actually helps
The wall mount is not a gimmick — it solves real problems. Tiny desks keep their surface. Kitchens get airflow above counter clutter. Kids’ rooms keep the water tank out of reach. Camper vans gain cooling without sacrificing a shelf. And because the mount needs no drilling, tenants lose no deposit. If none of those placement problems are yours, the cheaper CoolJet delivers the same class of cooling on a desk.
Editor’s analysis: placement is the product
Strip away the mount and Froza is a competent, unremarkable evaporative cooler: water-and-ice reservoir, directional cool stream, low-watt draw, the usual humidity ceiling. What the mount changes is where that stream can live. Evaporative coolers work best close to the person, and eye-level wall placement aims the air across a bed or sofa in a way desk units cannot without stacking books under them.
The temperature claims deserve the same treatment we give every number. The brand’s own site promises no figure at all — only “a noticeable temperature drop in 10 minutes”. The affiliate checkout promises 35 °C down to 17 °C, and the same brand publishes the specification that rules it out: 5 V at 1.0 A, about five watts. Removing eighteen degrees from the air in a room is work measured in hundreds of watts. Our evaporative versus compressor explainer covers the physics.
Gaps we flag: no published wattage, dB or tank size. The 30-day guarantee and 2+ unit shipping deal are stated plainly on the offer page, which we credit under value. Build scores 7.5 — the mount hardware is the differentiator; the body is standard class plastic.
Bottom line: if the wall mount solves a problem you actually have, Froza is worth its premium over desk-only rivals. If it does not, save the difference.

Honest alternatives
For actual room cooling in a rental, the least-invasive compressor route is a single-hose portable vented through a window kit you can remove on moving day — see our renter’s guide. For premium personal cooling that shrugs off humidity, Coolzy-Pro’s real compressor is the upgrade path. And for pure budget, a clip fan aimed over a tray of ice mimics a fraction of the effect for pocket change.
Frequently asked questions
How much can five watts actually cool?
Enough to make the stream leaving the unit cooler and damper than the air going in, at arm’s length, for as long as the ice lasts. Not enough to change a room. The brand’s own site is careful here — it promises “a noticeable temperature drop in 10 minutes” and attaches no figure. The 35 °C-to-17 °C claim appears only on the affiliate checkout, and five watts cannot deliver it.
Do I need to drill to wall-mount Froza?
No. The no-drill wall mount is the product’s signature feature and the reason renters shortlist it. It also stands on a desk if you prefer.
Is Froza an air conditioner?
No — it is an evaporative personal cooler. No compressor, no refrigerant, no exhaust hose. That means near-zero running cost and zero installation, and it also means it cools a zone, not a room.
What does Froza cost to run?
The maker does not publish wattage, but the personal-cooler class draws tens of watts. Even at a generous 60 W, ten hours costs a few cents. Model it precisely with our power consumption calculator.
What guarantee does Froza offer?
A 30-day money-back guarantee, plus free UK shipping on orders of two or more units, per the official offer page at the time of writing. Confirm current terms before ordering.
Froza or CoolJet — which is better?
CoolJet wins on price per unit at the larger tiers; Froza wins if you want it off the desk and on the wall. Same technology class, so climate limits are identical. Both appear in our apartment guide.
