### ⭐⭐⭐⭐⭐ A must-have for camping in the uk
*by A***L on 12 September 2024*

The media could not be loaded. This clever dual battery isolator has truly transformed our family's camping adventures. Given the nature of weather conditions, it brings peace of mind knowing that our campervan’s batteries won't fail us when needed the most. The voltage indicator is invaluable, as it provides up-to-the-minute updates on power levels, keeping us informed at all times. This weekend, during a fishing trip with my son, the system flawlessly handled our lighting needs along with managing the refrigerator and other electronic equipment, all without any issues.Setting up the isolator was straightforward, with the 5-metre cable providing ample room to install it wherever we needed, without any hassle. When we drove through rainstorms, it held up well thanks to its IP68 waterproof rating, which is ideal for our outdoor excursions in the Lake District. What we really appreciated was its mode that smoothly switches between batteries, ensuring the main battery never runs out of power. It's apparent that this kit was designed to be reliable and user-friendly. For those who love camping or embarking on road trips, this is a must-have addition to their vehicle.
