»Sandberg Solar charger 40 watts is a compact solar panel with a fine performance. I think it's a good compromise between effect and size of the panel. For the price, it's a fine transportable panel that can keep even smaller units with green power as long as the sun shines.«

»Since there are two outlets, so we can charge up to two external batteries at the same time, and since people usually don't take these devices with them empty, we can be sure that on a nice sunny day it can easily replace the time it takes to charge our phone, or maybe power your laptop with solar energy.«

»Overall the product is decent, it’s sturdy, and it’s easy to work with.«

»Really practical, these identical solar panels only measure 21x28x4.4 cm when folded, which is roughly the size of an A4 notebook with a maximum weight of 1.4 kg in 40W. Once unfolded, for 1 m of additional length, it will suffice to orient it perpendicular to the sun's rays for maximum charging power.«
