https://stream.echo6.co/videos/watch/b6c4fca9-14fd-4297-a07c-db7f54eed4f4 This is one of many useful little modules available from online marketplaces. It states in the listing that it is designed for use from 6V to 45V but I absolutely do NOT recommend that it's used above 12V. That said, with a suitably protected three cell lithium pack, a suitable solar panel and your choice of light, it could be very useful. The module does not have any charge control other than the blocking diodes between the solar panel and battery pack, so the battery MUST have protection against overcharge and over-discharge. If you get Deja-vu then it's because this handy little module was featured in an unbagging video. If you want to buy one then here's a link to the item on AliExpress (not a sponsor). This is an affiliate link, but that will not affect the price you pay. https://s.click.aliexpress.com/e/_c3cQYI59 This module would be suited to off-grid applications where low level comfort light was wanted at night. If you enjoy my videos, supporting the channel on Patreon helps keep it independent of YouTube's quirks, avoids intrusive mid-video adverts, gives early access, bonus footage and regular quiet Patreon live streams. https://www.patreon.com/bigclive Alternatively, for a single coffee contribution you can use PayPal:- https://www.paypal.com/paypalme/bigclive #ElectronicsCreators Wed, 17 Jun 2026 19:11:46 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/b6c4fca9-14fd-4297-a07c-db7f54eed4f4 All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
