On paper: a very large capacity at an aggressive price
With 3456 Wh of LiFePO4 capacity, an output rated up to 4000 W continuous (6000 W peak) and a price observed at 1899 €, the Allpowers R4000 aims for accessible high-end territory. It combines four mains sockets, one RV socket, two USB-C ports up to 100 W and four USB-A ports. Its wheels and telescopic handle help manage a weight of 45 kg, and a color touchscreen rounds out control via app and voice command.
The most serious issue: a capacity expansion to verify before buying
The product description highlights a capacity that can be expanded with additional batteries. In practice, this expansion does exist at brand level, with a compatible battery sold through certain sales channels. But on the official shop specifically linked by this site, no expansion pack for the R4000 is offered or even mentioned to date. A buyer interested in this feature should therefore verify its actual availability before buying rather than take it for granted.
Another point of caution: the maximum capacities advertised for an expanded configuration vary widely depending on the manufacturer page consulted, with a gap reaching up to a factor of three between the lowest and highest figures. None of these figures can therefore be considered reliable without direct confirmation at the time of purchase.
3600 W or 4000 W continuous? An unresolved ambiguity
The R4000's exact continuous power rating is not presented identically from one official document to another: some documents describe a 3600 W tier with a separate 4000 W surge mode, while the manufacturer's most recent product sheets list only two tiers, 4000 W continuous and 6000 W peak, with no intermediate mode. The product's own name rather suggests that 4000 W is the figure meant to be read as continuous. Either way, the power actually available stays high and sufficient for nearly all common home and professional uses.
Recharging: fast, with a figure that varies from document to document
The full mains recharge time is advertised at one hour on some official pages, and at around 1h12 on other pages from the same manufacturer, with this second figure appearing to reserve the one-hour claim for a combined mains-plus-solar or charging-station top-up. In cold weather, around 2 °C, a full recharge can take noticeably longer, on the order of 4 hours, a point worth knowing for winter use in a van or outdoors.
The 5-year warranty: the same catch as the rest of the lineup
The 5-year warranty used as a marketing highlight does not apply automatically. The manufacturer's official documentation places the R4000 in the same extendable warranty category as the rest of the lineup: a no-action baseline of 24 months, extended to 60 months upon online product registration. Refurbished units sold by the manufacturer, meanwhile, only get 24 months with no option to extend.
Solar charging: a report worth watching, not yet an established pattern
A degradation of the solar charge controller after about two years of use affects at least one unit, with power readings becoming erratic and making solar charging impossible. This report remains isolated to date for this specific model, which makes it a point to watch rather than an established reliability pattern like the one documented on a more compact model from the same brand. A buyer who plans to rely heavily on solar charging over the long term would do well to pay attention to this.
45 kg: the wheels help, but the weight is still real
The 45 kg weight remains the most frequently cited point, including by the manufacturer itself. The wheels and telescopic handle genuinely ease moving it from room to room or from point to point on a job site, but that changes nothing about the fact that this is a format designed for a fixed setup or a spacious vehicle rather than for carrying by hand.
Fan: quiet at low load, audible beyond that
Noise level stays contained below 500 W of load, then climbs to 48-52 dB between 500 and 1500 W, reaching 55 to 58 dB beyond that, a level comparable to a normal conversation at close range. This behavior is consistent across the few measurements available.
Connectivity: the clearest strength
With four mains sockets, one RV socket, two USB-C ports up to 100 W and four USB-A ports, the R4000 covers a lot of ground for demanding home or professional use. The color touchscreen stays lit permanently with no night brightness setting, a detail worth knowing for use in a bedroom or an enclosed space at night.
The price actually charged
The official price observed is 1899 €, against a list price of 3599 €. Other retailers charge a slightly lower rate, around 1799 €.
Who it suits, and who it does not
It suits anyone looking for a very large fixed or semi-mobile backup reserve, for the home, a spacious van or a demanding job site, who charges mainly from the mains.
It does not suit anyone basing their purchase on the capacity expansion promise without having verified it beforehand, nor anyone looking for genuine everyday carry mobility given the 45 kg.
