| Ease of use & hookup | 7.8One outlet for four vehicles, with an LED per bank. | 7.5Simple mode button and clear LEDs; The Drive notes a short cord and vague instructions. |
| Durability, weather & cold resistance | 7.5IP65, but only a 2-year warranty. | 8.7IP65, 5-year warranty and a strong long-term reputation; runs warm. |
