Goal Zero Yeti Lithium MPPT Solar Charging Optimization Module

This module really works. I noticed my Yeti charges much faster with the same panels. Installation was a breeze. Great value.

I can't say it's 40% faster, but I do see a noticeable increase in charging speed. Build quality is good. I'm happy.

If you have a Yeti and solar panels, this is a must-have. It optimizes the charge and I get more power even on cloudy days. The difference is significant.

It works, but I didn't see a huge improvement. Maybe my panels aren't big enough to benefit. Still, it's a decent product for the price.

Plug and play, basically. My Yeti now shows a higher input wattage and charges faster. The build is solid. Highly recommend for anyone using solar with Goal Zero.

Not a night-and-day difference, but it does help. I like that it's compact and doesn't add much bulk. Good value.

I've been using this for a few months and it's been flawless. My solar panels are always charging at the maximum possible rate. It's a well-designed product.

I followed the instructions, but my Yeti still charges at the same rate. Maybe it's not compatible with my panels. I'm returning it.

This is a must-have if you want to improve your solar setup. It's simple, effective, and affordable. I've already noticed faster replenishment of my power station.

I can't say the 40% increase is accurate, but it does seem faster. The quality is good and it feels durable. I'm satisfied.
