this is a great deal. I bought one for full price (was desperate whilst working away) about 2 years ago. Still going strong. Forget comparing the Poundshop ones as they aren't 'Made for iPhone' certified which means can stop working at anytime/when Apple push out firmware that stops the cheaper ones working. Heat from me
hotukdeals.com/deals/konekt-3-in-1-usb-charging-cable-at-pound-stretcher-in-store-3222173 3 in 1 here and you can charge 3 devices at the same time, while this one charges only 1. Cheaper and better IMO, nothing against this deal.
Can’t you buy these in Poundland? Not goodmans branded but the same style of two in one.
