The Einhell TC-AG 18/115 Li is a cordless 115 mm (4 inch) angle grinder, seventh in this guide at £74.99, with 4.6 out of 5 from 68 ratings. The headline sells it as a set 'with Battery and Charger', and the Style field agrees: '+ Battery & Charger'. Its own first bullet does not — it calls the tool 'TC-AG 18 Li – Solo', which in Einhell's Power X-Change range means body only, no battery and no charger. Both statements sit in the same listing, so a buyer cannot tell from the page which one turns up in the box.

The ratings do not reconcile either. The header says 68 ratings; the star breakdown lists 78 five-star, 13 four-star, 7 three-star and 2 one-star, which is 100 in total. And where the cordless grinders above it in this guide quote wattage figures no 18V battery could deliver, this one quotes no wattage at all — the only performance number in the listing is an idle speed of 8,500 rpm. Everything on this page is read from the Amazon listing, not from our own testing.
