Nope, that’s not a typo with a double-w. I guess the design of the can is supposed to look a bit like a battery. Not one of the premium batteries, but one of those cheap batteries you find in megavalue shops selling at £1 for a pack of 100, and that value branding does sadly reflect on the taste. It’s a clone with quite a watery taste to it, and quite a sticky and sickly aftertaste. Still, it does say “Recharge your battery” on the can, and with 40mg/100ml caffeine content it’s pretty high!
