I bought gold zero because they were the first company that was providing solid solar solutions. I have bought two 500 W yeti lithium ion batteries I have 150 W of panels. In the last year, one of the batteries will not charge with, plugging them into any power source, AC or solar. Recently, my 50 W panel has stopped transferring power to the battery. In Canada, a 500 W yeti cost me $1200 Canadian. I've had two years of service out of the battery and it no longer is rechargeable. Due to some problem with the 8 mm input.
Now the 50 W panel is not transferring power to the one battery that is working. This is a lot of money for stuff that does not work over the long-term. As I'm a full-time nomad I need these things to function flawlessly. I am not satisfied with goal zero products in general. I am seeking another supplier to fill my needs. Very disappointed. Do not recommend you buy any goals or products. In addition they will nickel and dime you for every cable connecter that should be included. I'm sure there are many other manufacturers that have surpassed the ones great reputation of goal zero.
