If you've ever been in the situation where your battery has gone flat and you wished you'd done something about it
before you've had to go grovelling under the car to attach a +ve jump lead to the starter motor live and any available earth just to get back in, then consider this "little" gem from Aldi.
I came across this more powerful unit earlier this week and so decided to replace my relatively low power output solar panel hooked up to the V70's constant boot live socket to keep the battery topped up, with this one from Aldi at £11.99.

Mine was delivered yesterday: on open circuit voltmeter it was kicking out 17.3V which dropped to 13.37V with supplied current showing as 0.29A when connected to the constant boot live under a clouded late afternoon sky.
I was so impressed at the output in low light levels I went to order another for my son's ragtop this morning (12/08/18), but apparently it is now sold out online.
However it is still currently available in their stores.
NB it is worth noting that there is an in-built diode protection circuit which prevents the unit acting as a current draw in darkness - so no overnight losses other than those from the alarm and Can-Bus monitoring systems which is what I'm trying to overcome in the first place!
It knocks spots off the others I've tried over the years; the only downside is that it is a little on the large side at 500mm x 350mm x 20mm but either horizontally or vertically mounted on a pair suction cup hooks it fits the rear or rear side windows of a V70 window without problem - so off to Aldi later today to get another one
