FlexSolar 40W Foldable Solar Charger USB C Portable Solar Panel Camping

Works great, delivers usually 27/28W It one time hit 30W , I can charge my 99wh Anker battery pack in about 4 hours ish ? I don't live in the UK I live in a VERY sunny place so if I don't hit 40W no one will and I don't expect the panel to reach that. Kind wish it had a way to be laid other than flat but I guess that's what you get for the price range

I was pleased to find that this panel does not have glass panels. This is a serious plus as they live in my backpack, they even have a little flex to them. The panels are actually embedded in what seems to be a solid rubber so they don’t get ruined by rain! When out in full sun this panel charges my phone quickly on a type c fast charge cable, impressive. Over all I would say the panel is great value for money, it’s robust and can handle the outdoors easily. Folds up to the size of an a4 sheet of paper, just thicker obviously. If 40w is all you need look no further, it’s been helping me for months. Lastly, if it’s a little overcast they still deliver power, just not under full thick rain cloud!

Impressive little pannel. Its capable of charging a 20,000mah power bank in a reasonable time under unideal conditions. Good price and good product

This panel seems to work fine, based on experience charging a powerbank, rather than measuring its output with any kind of meter. Over about 4 hours on a sunny afternoon in the UK it added 15% capacity to a 20000mAh powerbank. The one point to be aware of (nearly lost it a star) is that it is bulkier than I expected; it doesn't fold very flat, and the connector housing makes a bump on one side that looks a bit vulnerable to knocks. I got this intending to throw it in a rucksack, and it will need more careful packing than I expected, maybe with some underwear filling the space in the middle, and something wrapped around it.

Very poor performance Very heavy

Its enough to run 3 phones, 2 sets of wireless headphones, a 2 bike battery array (and occasionally a Samsung tablet + emergency power bank/bike battery booster and radio) for literally 24/7 (on a sunny day ofc, today was cloudy, so no tablet to preserve the charge). Does it output 19V? Nope, Best I saw was 12.8 via DC direct connection, however, that is still amazing and quoted cap is under ideal conditions). Folds small enough for a backpack (and has space in the middle when folded for the tablet, damn efficient) enough for off the grid living (until your batteries die as needs a buffer). Would have bought a second one if not for the price being raised from 35 to 50 squid.

Great piece of kit. Does exactly what it promises. Fast charges all of my devices in hazy sunshine and slow charges in slight shade (see photo 2). Also slow charges in dull cloudy weather, if you're desperate for some charge to make a call, etc. Those who say these don't work must not be placing them at an optimal angle to the sun. Make sure that you monitor the sun's position and use the carabiner hooks to mount accordingly. I've just kept all of my devices running through the Isle of Man TT in very changeable conditions and would strongly recommend this product 👌🏻

Awesome charging

Génial et pratique Sa légèreté permet de l'embarquer pour de grandes sorties en pleine nature

Pros: it supports fast charging. easy to carry , you can fold it Cons: it absorbs the sun heat aggressively Which will makes it slows down the charging speed , this is normal but really annoying because i have to wait more to charge my device

Wij hebben deze zonnecel aangeschaft voor het kamperen met de tent. Wij gebruiken daar nooit stroom. Nu met deze uitvouwbare zonnencellen, kunnen wij onze powerbank opladen en daar weer mee al onze telefoons, reader's en elektrische tandenborstels opladen. Na ontvangst heb ik de zonnecellen even getest en in ongeveer 2 uren was de powerbank (22800) opgeladen. Was niet constant stroom. We zijn dus zeer tevreden.

It recharged my 24k Anker power bank in around 3 hours. This solar panel is light and very good quality.

It works perfectly in the sunlight...I recommend it
