What You're Actually Getting
This is a 68W USB-C wall charger from Lenovo. One port, one job. It's the sort of thing you buy because your original charger is buried under your desk at the office, or because you want a dedicated travel one that doesn't weigh half a kilo.
Personally, I think 68W is a sweet spot. Enough to charge most mid-range laptops at full speed, handles phones and tablets without a second thought, and doesn't demand a bag of its own. The plug is UK spec, which sounds obvious but you'd be amazed how many people order the wrong one.
Who Should Actually Buy This
Look, if you've got a Lenovo ThinkPad or IdeaPad that charges over USB-C, this is a no-brainer spare. It also works fine with a MacBook Air, a Steam Deck, or pretty much any USB-C device that asks for under 65W or so. The Lenovo branding probably means the firmware plays nicely with Lenovo machines specifically.
Who shouldn't bother: if you've got a power-hungry 16-inch laptop that wants 100W or more, this won't cut it for sustained use. It'll charge slowly, and that's a bit annoying when you're mid-task.
The Honest Bit
There's no listed "was" price here, so I can't tell you it's a stonking discount. At around £16 it's not half bad for a branded 68W charger, but keep an eye out because these do pop up cheaper. The community heat on HotUKDeals is a decent signal though. Stock tends to move quick on stuff like this.
