I really wanted a bird bath. And if you want something bad enough the universe have its way of giving you what you want and more.
I found this lady on YouTube and she figured out a way to have a bird bath without the need of extension card on your yard. And you also don’t need solar power. And it’s very affordable. I just wanted to attract some song birds.
Anyway she buys these water pump for a few dollars and powers them using power banks. I though it was a genius idea. But then light turned on ... you know the idea light... bing! These power bank will also power many usb devices. Like a usb powered fan and usb powered lights. Perfect for camping and off gridding type of thing. The possibilities are endless. So right now. They are powering a usb fan while I sit in this hot ass van waiting for my boyfriend to finish installation.
As you can see they are affordable. I bought some from eBay ... they are as low as $5 and $10 and up.
I even bought one that can be charged with solar energy.
Let me know what’s powering your power banks.
