Carphone Warehouse accessory sales of portable Powerbanks saw a 60% increase over the weekend, indicating herds of Pokémon trainers headed to stores to avoid running out of phone battery at critical moments on their quest to catch Pokémon, says the telecoms company.

Stores in Devon and Cornwall saw the biggest increase in sales, suggesting many Pokémon trainers were hitting the coast at the weekend to enjoy the weather whilst continuing to try and ‘catch ’em all’.
