Some connected product functions might not be available. ** We call the NJORD® GO an ‘EV charger’ but technically speaking, it’s ‘Electrical Vehicle Supply Equipment’ (EVSE) that provides a safe supply of electricity to power the on-board battery charger in your EV. Most people use the term ‘EV charger’ so to keep things simple, we’re going to use this term as well.

Verdict
The clearest difference is ads: CTEK App at none against Garantera's shown. Garantera's advantage is update cadence (every 2 weeks vs monthly) and device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.
