This 300W power bank is foldable and comes with solar and built-in charger

[Redaktion]

A new power bank is said to offer particularly high output and does not require a charger for recharging, effectively functioning as one itself. The gadget is also available with the usual EU plug.

Not only are crowdfunded projects fraught with risk in themselves, but for something that could potentially burn down your house if poorly engineered, this calls for even more caution than usual.

a solar panel on something this size is pure gimmickry, and that tells you everything you need to know

Each side panel is what.. 40cm2 ? That'll be good for maybe 0.9 Watts tops, and let's overlook the fact you are cooking the battery by leaving it in the sun to 'charge' at around 1% per *hour*

I looked into this as the specs are amazing - but when looking a bit closer (or asking them any questions) it all falls apart super quick. Very sketchy replies, non of their numbers are making any sense in terms of physics, and different figures on their website vs campaign page...feels like its just a render with no actual product, and they still promise June mass production without any certifications etc done...a lot of people are going to lose their money here!
I made a quick YouTube video this week about it, search for Solly power bank Fake.
