HYUNDAI HY2300Si, 2.0 kW continuous, 2.2 kW maximum, 21 kg review

A 21 kg inverter generator with 2.0 kW continuous and 2.2 kW maximum output, two mains sockets, a 12 V DC outlet at 5 A and a USB port.

The bottom line The best-connected generator here, with both mains sockets rated, a 12 V outlet and a USB port. Like every generator in this family it publishes no tank size, no runtime with a load, no noise figure and no emissions class.

A 21 kg inverter generator with the outlet list its neighbours omit.

What you can actually plug in

Two 230 V 16 A Schuko sockets, a 12 V DC outlet at 5 A, and a USB port. Rated individually. Four of the six generators in this family never list their outlets, which makes this one of two that can be compared on what it will run at once.

The outputs

2.0 kW continuous, 2.2 kW maximum. A narrow gap between the two, which is characteristic of inverter generators — the electronics limit the surge headroom compared with a conventional machine.

The 12 V outlet

5 A. Useful for keeping a leisure battery from falling while the generator is running for something else. Not a charging solution: a flat 100 Ah battery at 5 A is a very long evening.

The four blanks this family shares

Tank size. Runtime with its load. Noise with its distance. Emissions class. Six generators, and not one publishes the last two.

What it gets right, and what it leaves out

Strengths

  • The outlets are listed individually with their ratings, which only this generator and the Scheppach manage
  • A 12 V DC outlet at 5 A, so a battery can be topped up directly
  • Both continuous and maximum outputs published

Compromises

  • No tank size and no runtime, so refuelling cannot be planned
  • No noise figure, only an ECO mode claim
  • No emissions class

Questions owners ask about this one

What is the 12 V 5 A outlet for?

Topping up a leisure battery directly, without the inverter stage or a separate charger. At 5 A it is a trickle rather than a charge — a 100 Ah battery would take a long time — but it keeps a battery from falling while the generator runs for another reason.

Why do outlets matter as a specification?

Because two sockets mean two appliances at once and one means one. Four of the six generators here do not list their outlets at all, which leaves the most basic usability question open.
