he charger, which is compatible with the rechargeable battery wand and the internal rechargeable battery, has a uniquely efficient design. Because of this design, the charger works extremely well even in low-light, north-facing windows, meaning the majority of rechargeable PowerView or SoftTouch shades connected to a Solar Charger won’t require manual recharging. The Solar Charger is a great solution if you have multiple rechargeable shades, hard-to-reach rechargeable shades and non-primary residences with rechargeable shades.
