Can I connect the clip lead directly to a battery?

Do not assume that is safe. Confirm a suitable charge controller, battery chemistry, charge profile and polarity first.

An internal storage battery is not itemized. Do not treat this solar charger as a confirmed power bank.

Plan a compact daylight charging kit with this three-panel folding solar charger. Its detailed source lists separate 18V DC and 5V USB outputs, a 480g weight and a selection of connection accessories. Folded dimensions help you check bag space before a trip, while the open size helps plan a charging stop. The nominal 21W claim is not a promise of delivered device power, and adapters do not establish universal laptop or battery compatibility.
