KINGSOLAR 39W Mono-crystalline Solar Charger Dual Output Solar Panel USB-5V/2.1A DC-18V/2.2A (Foldable, Portable, PowermaxIQ Technology)

I bought this 3 months ago, mostly to try it out for a few months before a 3 week road-trip over the summer. I've done similar length trips in my campervan armed with a handful of assorted power packs, charged from both the trusty 12v cigarette lighter socket when driving, and from mains overnight when it was available. And two kids who have phones and nintendos eating up the power... I've found that unless you're driving hours a day, the 12v socket isn't enough, and that not being guaranteed mains meant that I was struggling after a fortnight... So, a solar alternative was required and given i'll be in France & Spain, it may be my primary power. On UK dry-runs during Apr, May & Jun, I can confirm it works really, really well. For sure, really brilliant sunshine & a clear sky gives the best results - really quick. On a sunny or overcast day, it'll get there. You get the blue ("i'm working!") light lit even when I lay it out on the van bed during the day while we're out and about. I think in the UK you really want the panel 'on' all the time - 2 hours in the morning just won't cut it. My batteries are a mix of assorted large 12 - 26mAh types, and all have simple 4 LED indicators - so I can't be giving hard numbers. I have found that having a couple of packs means I can leave one charging all day and take another with me for phone top-ups, and swap them round each day. I've not felt I've needed to be careful with power during Easter and May half term breaks this year, so that's a win. For a long weekend, just take a really large battery pack or two..! Quality wise, nice thick 'canvas' type cover, the panel side feels a thick, plastic material. The loops are maybe a little flimsy, but no issues so far, and I use them to hang the panel on a 'mount' to angle it towards the sun better. Not bothered about the small pocket to be honest. Folds up securely with the Velcro, since I tend to keep it open all the time to catch the rays as early and as late as I can..! To summarise: keeping the panel always 'on' and swapping battery packs for a charge-one / use-one kind of cycle, even with the UK weather, it's keeping me going - very happy.

Ich versuche seit vielen Wochen dieses Unnütze Teil zu Reklamieren. Das einzige was die Firma mir angeboten hat ist das sie mir den Spannungswander (Der hier wohl defekt ist) aus China zusenden und ich ihn selbst Einlöten soll. Dabei erlischt selbstverständlich die Garantie. Da bei so etwas ..noch dazu Als Laie die Chance Größer ist es zu zerstören als zu Reparieren wollte ich eine Andere Lösung,daraufhin brach der Kontakt zum Hersteller ab....

tre tre bien je m en sers presque tous les jours je recharge ma batterie de 12v est mon smartphone et autre j en suis tre satisfait pour le prix

Hätte mir ein wenig mehr Leistung erwartet. Aber es ist einfach zu bedienen und bei sehr viel Sonne auch halbwegs effektiv. Alles in allem zu empfehlen.
