We bought this charger as a temporary charger to hold us over until having a 48A unit installed. We had it now for about a month and it still is our main charger in the garage.
Without it getting hot, it reliably charges our EV at about 3.7 kW (on a 240V/20A outlet) which is enough to plug it in after work and be fully charged in the morning from about 40%. The carrying case is great and it is small enough to fit in a little compartment under the cargo space, so it's a perfect emergency charger when traveling to friends and family.
