Hello, yes, the GB70 can also do this with ease. I have an Ioniq myself and have already used it for this. However, the GB70 is completely oversized for this. My tip: it's better to choose a smaller, handier and lighter booster for this purpose!
Hello TheDeymen I bought a cheap booster in the Landi. 500 W cold, 1000 W boost unfortunately did not work The continuous current was too weak. Could not start the car. I returned the Landi Boster. Don't know if the GB40 would be enough.
