Review on sonnenBatterie by Gary Shakeone

It's easy to use, it has great performance in terms of battery life (about 6-7 hours), so I can charge my phone while out hiking or at work without having problems with power issues when running low batteries during travel time! Also very good price/performance ratio compared t o other solutions available for this type applications like Sonnet PowerCore+2S etc., which are usually much more expensive than these alternatives from SONNEN BATTERSE ECO! I like how easy it was to install, as well as use. It's very intuitive! Also love using it for my solar panels and charging up during the day when there isn't much sun out. Sometimes you have to wait about 10 minutes or so between charges if your car has been parked in direct sunlight all day long. We are trying to cut down our carbon footprint by reducing usage of gas powered vehicles. This system allows us to charge at night while we sleep and then re-charge throughout the day.
