Carbon 2026: what owners actually say
Early commenters are intrigued by Carbon's smartphone-charging concept but repeatedly flag its chunky size as a problem for smaller wrists, with charging efficiency still unverified.
What owners complain about
- Too chunky for smaller wrists SOME
Multiple commenters say it is 'a big chunky for my medium-sized-man-wrists' and 'a tad too chunky for the female wrist'; even a sympathetic commenter concedes 'that is thick'.
- Charging efficiency unproven FEW
A commenter asks how many phone charges it delivers, how many milliwatt-hours it holds, and predicts it is 'massively inefficient' — joking they 'might have to wave my hand constantly in circles for it to work properly'. The maker's reply confirms size trade-offs exist to preserve phone-charging battery capacity, but no numbers were given in the comments.
- Marketing overreach FEW
One commenter calls the 'splash of press coverage logos' on the page 'a bit over the top'.
- Key specs unanswered FEW
Basic questions in the comments — charge count, energy per phone charge, capacity in mWh — went unanswered in the sample, leaving core performance claims vague.
What owners love
- Thickness has fans
One commenter explicitly liked the bulk — 'That is thick... but I like it' — showing the size that puts others off is a draw for some buyers.
- Material options attract interest
The Slate & Leather option prompted at least one commenter to say that's the configuration they'd buy.
- Size benchmarked against real watches
The maker states Carbon's dimensions were sized using popular watches, which some commenters treated as a reasonable defence of the footprint.
Surprising patterns
- Almost none of the sampled discussion is actually about the product: the bulk of comments concern NEOM greenwashing, Google's CO2 emissions, climate politics and an unrelated Bajaj Pulsar 2026 motorcycle, suggesting owner discussion of Carbon itself is still very thin.
- The thickness complaint and the maker's explanation are directly linked — the maker admits making it smaller would mean dropping the smartphone-charging battery, so buyers are effectively choosing between size and the headline feature.
- Commenters are split on the same attribute: the chunkiness that two people cite as a dealbreaker is exactly what one person liked.
WHO SHOULD SKIP IT
Buyers with small or medium wrists who want a compact device, or anyone who needs verified charge counts and capacity figures before purchase, should skip it per these comments.
