Einhell TC-PG 25/1/E5: our full review

A small petrol generator whose 15-litre tank, identical to its bigger sibling the TC-PG 35, gives it the best runtime in its segment, yet its guaranteed sound power of 96 dB(A) is just as high despite 500 W less output.

The essentials

The TC-PG 25/1/E5 delivers on a precise promise: a 15-litre tank, identical to its bigger sibling the TC-PG 35, for an official runtime of 12.5 hours at two-thirds load, the best of the three conventional petrol generators compared here. Its continuous output of 2100 W, with a tight 14% gap up to the 2400 W peak, is honestly stated and covers most household backup or light site work. The real friction point lies elsewhere: its guaranteed sound power of 96 dB(A) is exactly the same as the TC-PG 35's, despite that model producing 500 W more, so there is no quietness to be gained by choosing the smaller unit. With no wheels and no USB port, and a non-inverter current best avoided for sensitive electronics, it remains a solid choice for a power cut at home or the odd day on site, provided you accept the noise of an open-frame generator.

Strengths

  • A 15-litre tank for only 2100 W continuous: an official runtime of 12.5 hours at two-thirds load, the best of the three petrol generators compared here
  • Tight gap between continuous and peak output (2100 then 2400 W, 14%): an honestly stated power rating, with no inflated headline figure
  • AVR regulation that steadies the voltage across both 230 V sockets, useful the moment a tool or a fridge starts up
  • The lightest of the three conventional generators compared (36.8 kg dry against 42 and 45 kg), even without wheels
  • Front-panel analogue voltmeter, overload breaker and low-oil safety cut-out, with a two-year manufacturer warranty
  • No recall or recurring structural fault identified for this model, which is widely distributed across Europe

Limitations

  • Guaranteed sound power of 96 dB(A), exactly matching the TC-PG 35 despite 500 W less output: no quietness gained by choosing the smaller model
  • Not an inverter generator: AVR regulation steadies the voltage, not the waveform, a point of caution for sensitive electronics (laptops, audio gear)
  • No wheels at all: 36.8 kg dry, close to 48.5 kg once full of petrol and oil, a two-person lift or a boot job
  • Starting is by recoil cord only, with no electric assistance
  • No USB port and no 12 V output for charging a small device directly
  • Continuous output of 2100 W, the lowest of the three conventional petrol generators compared (2400 and 2600 W for the other two): best reserved for uses that do not require stacking several heavy loads at once

2100 W continuous, 2400 W peak: power stated without inflation

The TC-PG 25/1/E5 is a conventional petrol generator (synchronous alternator, no inverter stage) built on a fixed tubular frame. Its official spec sheet rates it at 2100 W continuous and 2400 W maximum, at a rated current of 9.1 A at 230 V. The gap between the two figures is only 14%, tight compared with many entry-level generators that quote a peak figure well beyond what they can actually sustain.

Two 230 V sockets sit on the front panel, alongside an analogue voltmeter that shows the delivered voltage at all times, a handy reference the moment another appliance is plugged in. A continuous output of 2100 W covers most household backup or light site needs (lighting, a fridge, a pump, power tools), but it will not stack several heavy loads at once.

15 litres, the best runtime of the three: 12.5 hours at two-thirds load

The real selling point of the TC-PG 25/1/E5 is its tank. At 15 litres, it matches exactly the capacity of its bigger sibling, the TC-PG 35, a size normally reserved for far more powerful generators. Set against a consumption of around 1.2 litres per hour at two-thirds load, that capacity yields an official runtime of 12.5 hours, the best of the three conventional petrol generators compared here.

Tank capacity of each generator: the TC-PG 25/1/E5 and the TC-PG 35 share the same volume, nearly four times that of the SDMO Perform 3000.

The TC-PG 35, despite being more powerful and fitted with the same 15-litre tank, tops out at 10.7 hours under the same reduced-load conditions: its higher consumption (around 1.4 L/h) eats into part of the advantage the large tank provides. The SDMO Perform 3000, with only 4.1 litres, runs for 3.2 hours at 75% load, a refuelling rhythm in a different league.

Runtime quoted at reduced load: 12.5 hours for the TC-PG 25/1/E5 at two-thirds load, 10.7 hours for the TC-PG 35 at two-thirds load, 3.2 hours for the SDMO Perform 3000 at 75% loadTC-PG 25/1/E512.5 h (2/3)TC-PG 3510.7 h (2/3)SDMO Perform 30003.2 h (75%)
Runtime quoted at reduced load for each generator. The load fraction differs (two-thirds for the two Einhell units, 75% for the SDMO): the figures remain indicative for general comparison, not strictly equivalent.
Worth noting: these runtimes are quoted at reduced load, not at maximum continuous power. Run flat out at 2100 W, the TC-PG 25/1/E5 will use more fuel and run for less time, more likely 7 to 8 hours in that case.

96 dB(A) guaranteed: as loud as the TC-PG 35, despite 500 W less

The guaranteed sound power of the TC-PG 25/1/E5 reaches 96 dB(A), the figure declared under European regulations on noise emissions for outdoor equipment. At the operator position, the official level is 73.1 dB(A).

sound pressure at operator position

That figure is surprising at first glance: it is exactly the same level as the TC-PG 35, despite that model producing 500 W more continuous power, and the same as the SDMO Perform 3000. Contrary to intuition, a less powerful generator is not automatically quieter: the noise of an open-frame unit depends mainly on the engine architecture and the absence of acoustic enclosure, not solely on the electrical output. Choosing the TC-PG 25/1/E5 over the TC-PG 35 buys lighter weight and more runtime, not more quiet.

The Honda EU10i, the only inverter generator already reviewed on this site, shows what an enclosed architecture buys: a guaranteed sound power of 87 dB(A), 9 dB(A) less, a difference very clearly audible, at the cost of a quarter of the continuous power (900 W) and a noticeably higher price. In practice, the TC-PG 25/1/E5's level rules out camping use or running it near homes in the evening; it remains suitable for daytime site work or the odd backup run, kept well away from occupied rooms.

AVR regulation steadies the voltage, not the waveform

AVR (automatic voltage regulation) keeps the output close to 230 V regardless of the load, within the 2400 W available. That is a genuine benefit for power tools or lighting, which cope badly with voltage dips as a motor starts up. AVR acts on the amplitude of the current, though, not on the shape of its wave: a conventional generator like this one produces current straight from the synchronous alternator, without the electronic reconstruction of a smoothed sine wave that an inverter generator provides.

Worth noting: no harmonic distortion figure is published for this type of generator, a common gap on conventional units in this price bracket. For power tools, a fridge or lighting, that causes no issue at all. For a laptop or sensitive audio or photo gear, an inverter generator remains the safer choice.

Starting is exclusively by recoil cord, with no electric starter and no battery to maintain. An overload breaker protects both 230 V sockets, and a low-oil safety cut-out automatically stops the engine before it can be damaged.

4.1 kW at the engine, 2100 W at the socket: what the spec sheet does not say

One figure in the official documentation is easy to miss: the 208 cc four-stroke engine develops a maximum mechanical output of 4.1 kW (5.6 hp), almost double the 2100 W of continuous electrical output quoted on the front panel. The gap is neither an error nor marketing excess: part of the engine's mechanical power goes into driving the alternator with a working margin, rather than being fully converted into continuously usable current. That margin keeps the engine from running flat out all the time, a factor in longevity rather than a weakness.

A technical curiosity: the SDMO Perform 3000, fitted with a Kohler CH270 engine of professional standing, shares the exact same 208 cc displacement, yet delivers 300 W more continuous electrical power (2400 against 2100 W). The gap shows how much an engine's tuning and design, beyond displacement alone, determine the electrical power that finally reaches the sockets.

36.8 kg dry, close to 48.5 kg full: the lightest of the three, but no wheels

The TC-PG 25/1/E5 weighs 36.8 kg dry. Of the three conventional petrol generators compared here, it is the lightest: 5.2 kg less than the TC-PG 35 (42 kg) and 8.2 kg less than the SDMO Perform 3000 (45 kg). That figure is still a dry weight, though: full of petrol (15 litres, around 11.2 kg at a petrol density of roughly 0.745 kg per litre) and engine oil (around 0.6 litres), the unit approaches 48.5 kg ready to run, a figure rarely highlighted on sales sheets.

dry weight

The tubular frame protects the engine and doubles as a carry handle, but it has neither wheels nor a telescopic handle. Unlike the TC-PG 35, which rolls on two large wheels despite its 42 kg, the TC-PG 25/1/E5 is a two-person lift or a boot job. The SDMO Perform 3000 shares this same lack of wheels, at a higher weight still. Being the lightest of the three helps when lifting it, but it is no substitute for wheels once the unit needs moving around a site.

Build and the Classic range: the same base as the TC-PG 35

Einhell is a German consumer tool maker based in Landau an der Isar, Bavaria, in this market since the 1960s. The TC-PG 25/1/E5 belongs, like the TC-PG 35, to the brand's "Classic" range, positioned for occasional use rather than continuous, intensive professional work. The standard manufacturer warranty is two years.

No recall or recurring structural fault shows up for this model, on sale for several years and widely distributed across Europe. The real friction points sit with the noise already covered and the lack of wheels, not with early mechanical failure.

Against the TC-PG 35 and the SDMO Perform 3000

At around £303, the TC-PG 25/1/E5 sits as the brand's entry-level petrol generator, just below the TC-PG 35. The table places the three closest conventional generators in the catalogue by range and power.

Against the TC-PG 35, the gap comes down to three specific points: power (2100 against 2600 W), wheels (absent here, present on the TC-PG 35) and runtime, where the TC-PG 25/1/E5 has the edge despite an identical tank. Noise does not separate the two models at all: 96 dB(A) either way. Against the SDMO Perform 3000, the gap is wider on continuous run time (12.5 against 3.2 hours on a full tank) and on weight, both favouring the TC-PG 25/1/E5, while the SDMO keeps the edge with its Kohler engine of professional standing and a longer warranty (3 years against 2). The choice comes down to this: tank and light weight for the TC-PG 25/1/E5, power and wheels for the TC-PG 35, engine and warranty for the SDMO Perform 3000.

Who the TC-PG 25/1/E5 suits, and who it does not

It suits anyone after a long tank runtime at a contained price for the odd household backup or a small site job, and who can live with the noise of an open-frame generator and the lack of wheels.

It does not suit anyone who needs more than 2100 W continuous (the TC-PG 35 or the SDMO Perform 3000 fit better), who needs quiet for camping or for running near homes in the evening, who needs an inverter generator for very sensitive electronics, or who needs a wheeled frame to roll the unit around a site rather than carry it.

Frequently asked questions

Einhell quotes 12.5 hours at two-thirds load, thanks to the 15-litre tank. At full continuous power of 2100 W, consumption is higher and the real runtime shorter, more like 7 to 8 hours; it runs considerably longer if only a few lamps and a fridge are connected.

Yes. Both carry an identical guaranteed sound power of 96 dB(A), despite the 500 W gap in continuous output. Choosing the smaller model brings no gain in quietness.

Yes. A domestic fridge typically draws 100 to 200 W once running, with a compressor start-up surge that the 2400 W peak absorbs without difficulty.

It is not an inverter generator: AVR regulation steadies the voltage but not the waveform. A laptop charger generally tolerates that well, but for genuinely sensitive equipment, an inverter generator remains the safer choice.

The TC-PG 25/1/E5 offers a far longer runtime on a full tank (12.5 against 3.2 hours) thanks to its 15-litre tank against 4.1 litres, and it is 8.2 kg lighter. In return, the SDMO Perform 3000 carries a Kohler engine of professional standing and an extra year of warranty.

Ordinary unleaded petrol, E10-compatible, is fine. The engine oil level (around 0.6 litres) is worth checking before every use: the built-in safety cut-out stops the engine if the level runs too low.
