Hello everyone.
I just bought a 10400mAh Xiaomi power bank and thought it would be nice if I could illuminate my room with it, in addition to charging my phone.
Considering it provides 2A current at 5V, I am assuming it can run a 10W (P = IV) LED light (correct me if I'm wrong.)
But I have very little practical electronics experience and thus ask your help in building such a light.
So what is the maximum power rating I should go for, considering I don't want to affect the power bank's longevity?
What sort of LED's should I look for?
Is there a need of an LED driver or just a passive heatsink will do?
Are there already cheap ready to use alternatives available?
I will be grateful if someone with experience could post a tutorial regarding this query.
