While it’s nice to have the solar panel as a last-resort type backup, it does not do much, so consider this product as its value as a regular charger before purchasing. When left on my window sill for days in direct sunlight, I was only able to get this charger up to about 25%. This is better than nothing, but solar will not be your primary charging source with this battery.

This adapter is a decent multi-use adapter with good audio quality and straightforward operation. Due to the fact that it does not turn on automatically when it receives power I would recommend it for use with a TV or home stereo over a car. When paired with a set of APT-x headphones there is almost no lag, making it good for watching movies and TV compared to other TX/RX devices I’ve tested.

Perhaps I received a bad copy, but the treble with this speaker is overemphasized and cuts like a razor. To achieve reasonable bass and mid-tones volume, the treble will be too high and almost painful. I was able to solve this problem by placing some thin foam between the speaker grill and the cones (the front grill just pops off) and after I did that they sound alright.

These Q12’s are some of the better performing budget Bluetooth headphones I’ve reviewed, with more bass than competing models. The best part is, even with more bass the treble comes through crisp and clear, striking a good balance between high and low tones. When combined with the decent build quality and battery life, these headphones make it onto my recommendation list.
