Halorin 900 W continuous, 2000 W peak, 12 V or 24 V review

A converter titled 2000 W that delivers 900 W continuously, accepting both 12 V and 24 V input, connectable by battery clamps or a cigarette lighter plug.

By Jean-Benoit Buisson

The bottom line A dual-voltage converter with good protections and two ways to connect, whose title advertises a peak it cannot sustain. The cigarette lighter lead and the 900 W rating are not compatible with each other, and the listing does not say so.

A converter sold on its peak and rated well below it.

Two numbers, one in the title

900 W continuous. 2000 W peak. The title carries only the second. Sizing against a peak is the commonest mistake on this shelf and the title invites it directly.

Two ways in, one of them limited

Battery clamps and a cigarette lighter plug. The clamps will carry what the converter needs; the socket will not. At 12 V, 900 W is roughly 75 A, and vehicle sockets are fused at a fraction of that. The listing offers both connections and never mentions the difference.

What is properly specified

Seven protections named individually. Automatic 12 V and 24 V input detection, which two other converters in this family manage and four do not. A colour LCD showing battery voltage and load in real time — useful precisely because it warns before the low-voltage cut-off acts.

What is not

Input current. Fuse rating. Cable size. Idle consumption. The first three are what connect the converter to the battery safely, and the fourth is what it costs to leave on.

German, French, Italian and Spanish Amazon stores quoted about 53 € when this page was compiled.

American Amazon catalogue carries an entry for it, with nobody selling.

British Amazon store returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

What it gets right, and what it leaves out

Strengths

Accepts both 12 V and 24 V input, which most converters here do not
A colour LCD showing battery voltage and load status in real time
Two connection methods supplied, so it suits a vehicle socket or a direct battery connection

Compromises

The title says 2000 W and the continuous rating is 900 W — the peak is the headline
A cigarette lighter connection cannot carry 900 W on any ordinary vehicle circuit
No input current, no fusing and no idle consumption

Questions owners ask about this one

Which figure should be used for sizing — 900 W or 2000 W?

The 900 W. Continuous output is what an appliance list is compared against; a peak covers the instant a motor starts. The title gives only the peak, which is the number that sells and the wrong one to plan with.

Can the cigarette lighter lead carry 900 W?

At 12 V that is around 75 A, which is far beyond any ordinary vehicle socket — most are fused between 10 and 20 A. The lead is for light loads; the clamps are for the rest, and the vehicle handbook holds the socket’s real rating.
