Review on XTAR VC4 Universal Battery Charger LCD Display 4 Bay Charger for 18650, 20700, 21700, AA, AAA, C, D Batteries by Akane Rajakumar

I thought this charger would be great for my 18650/21700 batteries, it charges most of the time. I'm already noticing that I have to wiggle or unplug the power cord for this charger to work, sometimes when it takes 6 to 8 hours to charge just 2 21700's, there have also been instances where I'm in a 10 hour shift got home from work that the batteries still aren't charged (my wife is at home so I won't leave her unattended) and I find out the current has dropped to 0 amps (really) so let's get started on the old one, turn it off and try the method again and it will charge normally (I know these are not bad batteries because it happens to everyone). New charger, if you know of one I'm open to suggestions!
