For owners of small power stations who value a sturdy, long-warranty 100 W panel from a major brand. Shoppers chasing the lowest price per watt or USB charging can do better.
Amazon $144.99 Renogy $144.99A light, packable panel for campers who mainly charge phones, power banks and small power stations, and it did well in independent testing. Anyone filling a larger station should step up to 100 W or more.
Amazon $62.99 FlexSolar $69.99A low-profile 100 W panel for curved or weight-limited van, RV and boat roofs, especially where an all-black look matters. On a flat roof that can take the weight, a rigid panel lasts longer for less money.
