I’ve been using Octopus Electroverse for public charging and it’s been one of the easiest apps to manage day‑to‑day. The big advantage is having one card and one app that works across loads of different charging networks, so you don’t need to juggle multiple accounts. Pricing is clear, the app is reliable, and it’s been especially useful around London where roaming coverage is strong. They also do discounted “plunge pricing” events, and offer ongoing discounts on certain parter operators, including Osprey. If you want a simple way to access most chargers without the hassle, Electroverse is a top choice.
