Yep... I have a similar solar charger.
It works fine as a high capacity auxiliary battery, but the solar charging capacity is worthless.
One issue that is a bit annoying with it is that it has an auto-off function. A good idea, but it causes problems with float charging from the battery pack.
There may be some larger (fold out) solar chargers that would work, but they need good noon sun exposure.
