I didn’t realize the Wasserstein had it’s own embedded battery as well for charging off solar panel. Instructions say to give it a good 8-10 hours in sun before plugging into a fully charged WCO. There isn’t a separate USB charging port so have to go with the sun.
How long did your Wasserstein panel require charging? I have two of them that have been outside. One location since weekend with probably 30% sun exposure and now one in my back yard with my 400W panel for couple days and still not powering up. I’ll give it a few more days but so far disappointed as I had hoped to purchase more. If my luck changes I will update. Wondering if I am being impatient, defective run of units, or something has changed with beta firmware on WCO preventing them from working
I think one of my Wasserstein may be defective but I did finally get one to fire off on a charge. It seemed to give about a 15% recharge before it fell off to needing to recharge. I would say be sure to place in a very sunlit location… I think partial may just not cut it at all. Company is sending me out a replacement so I can’t complain.
I can’t restate enough… get it out in some solid sunlight for 2-3 days just to be sure before plugging in. At least you won’t question if it is working or not as no external indicators on device itself it is ready to go.
For what it’s worth, I’m using a solar panel for a different device that needs to work overnight. I face the panel to get more of the late afternoon sun so that all the charging comes just after the sun reaches it’s peak instead of early in the day. It picks up enough ambient light in the morning to at least keep up. So I get a full charge at mid afternoon instead of the morning. Seems to work better than charging early.
I just plugged in a Wasserstein solar panel to my WYZE outdoor cam. It appeared to be charging - but then in the morning it was at 0% and it looks like it killed the camera. In the camera “accessories” control area in the software it has a prompt for a solar panel option and when I select it - it says to update my base station to the newest firmware… which it already has. Wondering if I am doing something wrong here. Panel was left to charge in sun for 3 days.
