L.R.A 78 Posted August 27, 2016 Share Posted August 27, 2016 Hi guys!I have a little problem here. So I want to make a robot with 2 servo motors. To make it small and easy to use for the kids at the club, I want to use a power bank to power everything. Well I've heard some powerbanks have a minimum current before they shut down. I don't want to use a resistor or a pulsed load to keep the powerbank on if that's the case.So I would like to know if anyone has had experience in using these powerbanks and knows it's good to use with just a microcontroler drawing power from it - the robot has servos but sometimes it can just be standing still.I'm thinking of using this ones (they need to be about 100x25x25mm or less)http://www.ebay.com/itm/USB-2600Mah-Portable-External-Battery-Charger-Power-Bank-for-Cell-Mobile-Phone-/141564208385?var=&hash=item20f5e26501:m:mjdVxgZQJgBThymbmYBeIUAIf anyone could help it would be greatly appreciated Quote Link to post Share on other sites
