DOKIO 100W Portable Foldable Solar Panel Kit for 12V Battery Charging

- 100W, folds to 19 x 26 inches
- PWM controller with USB ports
- 9.84 ft cable
Our take
Anyone building a first battery charging setup at the lowest outlay finds it a sensible place to start.
Why it made the shortlist
Dokio ships this 100 watt panel with a standalone PWM controller that guards a 12 volt battery from reverse polarity, overcharge, overload and short circuits. In its folded state it measures about 19 by 26 inches and weighs roughly five to six pounds.
This entry pick on price here, it still includes dual USB ports.
A 9.84 foot cable lets the panel sit in sun while the controller stays in shade, and the USB ports run phones and lamps when attached to a battery.
Where many 100 watt kits skip the controller, this one includes it, which is the practical reason it leads the value tier.
Small campers, tents and emergency kits suit its weight and size, and the listing is candid about power station input caps of 60 watts and similar.
What works
- Controller and USB ports included
- Light enough to carry by hand
- Long cable keeps gear in shade
Watch out for
- PWM controller wastes some energy
- One hundred watts is slow for fridges
