A secure mounting job needs attention after the first installation
One accessory I hadn't considered discussing before is EcoFlow's WAVE Series Stabilizing Strap Kit. It's designed to secure the WAVE 2 or WAVE 3, together with its add-on battery, to a horizontal surface in places such as RVs and yachts.
What caught my attention is that EcoFlow specifically recommends checking the screws and strap connections regularly because bumps can cause them to loosen. There is a real mechanical reason behind that recommendation. Under repeated transverse vibration, small movements can occur between the surfaces held together by a fastener.
Over time, this can reduce the clamping force and contribute to self-loosening. A mounting arrangement can therefore feel perfectly secure when first installed and still need periodic inspection after travelling over rough roads. I also appreciate that EcoFlow recommends using a wooden board on the mounting surface to avoid damage from drilling.
