Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.
What holds its value across DeWalt
- Brushless XR tools, which are marked on the housing and are substantially more capable than the brushed versions that look almost identical
- Healthy 18V XR batteries, particularly the higher-capacity packs, which frequently sell for more than the tool they came with
- FlexVolt tools and packs, which run at two voltages and are the only route into the 54V range
- Complete kits with the charger, the case and both batteries, which sell far more readily than a bare tool at a proportionate price
What pulls DeWalt resale value down
- Dead or tired battery packs, which are the single biggest deduction on any cordless tool and which cannot be judged from a photograph
- Brushed motors on tools that also exist in a brushless version, since buyers who know the range will hold out for the better one
- Missing chargers, which are inexpensive individually but immediately make a kit incomplete in a buyer’s eyes
- Cracked gearbox housings and stripped chucks, which on a drill are the failures that end the tool rather than merely mark it
Identifying and dating yours
- The model number is on the nameplate on the tool body, and the date code stamped beside it gives the year and week it was made
- Brushless tools carry the XR badge and the word brushless printed on the housing — photograph it, because it changes the price materially
- Battery packs have their capacity in amp-hours printed on the label, and many have a charge-state button worth pressing on camera
What lifts any generator, whatever the label
Generators are judged on running hours and how they start, and a machine that has sat unused for years is often harder to sell than a used one.
- Inverter generators, which are quieter and cleaner
- Low running hours with documented servicing
- Starts readily from cold
- Clean fuel system with no stale petrol residue
And what pulls one down
- Hard starting from stale fuel and gummed carburettors
- High running hours with no service history
- Noisy open-frame models in residential use
- Corroded fuel tanks
Working out what yours is worth
- Start it from cold and run it under load
- Note the running hours if a meter is fitted
- Drain and refresh the fuel before demonstrating
What to state in the listing
- Continuous and peak output in watts
- Fuel type, tank capacity and approximate run time
- Whether it is an inverter generator, and what sockets it has
- Running hours if known, service history, and that it has been tested under load
Output, type and fuel: “2.5kW Petrol Generator, Inverter, 4 Stroke”. Output in watts or kilowatts is the search, and inverter models are a distinct and higher bracket because they produce clean power for electronics. Say the fuel type and whether it has been serviced.
Preparing and photographing it
- Start it and run it under some load, and note the hours if it has a meter.
- Check the oil, drain the fuel before transport, and note the fuel type and tank capacity.
- Test every socket with something you can see working, and check the RCD or breaker if fitted.
- The whole generator from a three-quarter angle
- The control panel with every socket and the breaker visible
- The engine, plate and hours meter if fitted
- The fuel tank, oil filler and any rust, leak or damage
When it sells best, and handing it over
Lifts in autumn and winter around storm season and power cuts, and in summer for events and camping. Tested working machines sell quickly whenever demand spikes.
Drain the fuel before transport — a fuelled generator on its side leaks and is a fire risk. Collection is usual given the weight.
What buyers ask
Should I sell DeWalt tools with or without batteries?
With, if the packs are healthy. Batteries are most of the value to a buyer who is not already on the platform, and a complete kit sells much faster than a bare tool.
How do I describe battery condition honestly?
State the age, the amp-hour rating and how long a pack lasts under real use. Buyers expect some degradation; what they will not accept is finding out after the sale.
How much is a DeWalt generator worth?
Roughly £88 to £550 depending on condition, against £80 to £500 for generators generally. The identification points above are what move a listing to the top of that range.
What the fees would take elsewhere
At the mid-range £319 for a DeWalt generator, against what the commission marketplaces would deduct:
| Platform | Fee | You keep |
|---|---|---|
| Poshmark | −£64 | £255 |
| eBay | −£43 | £276 |
| Mercari | −£32 | £287 |
| Etsy | −£21 | £298 |
| WishThrift | −£0 | £319 |
Seller-side rates verified 26 Jul 2026, percentages only — the per-order and processing charges those platforms add are excluded, so the real gap is wider.
