That said, in full May afternoon sunlight, this charger easily lives up to its manufacturer's claims - I've measured 430 mA at 13 V, which is nearly five and half watts, compared with the spec of five watts.
However, four hundred milliamps is only a tenth of what a mains-powered charger will supply, so this solar charger is more suitable for battery maintenance than serious recharging. But for applications like leisure batteries in caravans or boats, or keeping a battery charged up for lighting a shed, or maintaining the battery in a car that's only used at weekends this charger appears to be ideal. Its environmental rating is IP 65, so it's dust-tight and rainproof.
Recommended, especially at the current Amazon price of just under £25.
So, if you are buying this for a car, think again.
As others have pointed out in reviews, this solar panelled charger is a trickle charger and does not give the same high level zap as chargers designed to revive dead car batteries from scratch in the shortest time possible.
That aside, it still does give remarkably good results for those needing a low-level charge. The solar panel is surprisingly large, which is quite reassuring, and on a sunny day will get up a decent charge -roughly a tenth of that of a full power battery charger. The need for a sunny day may put off some users but if you would like to be a little greener in your energy use, this is a way of extending the use of solar power within the home. Surprisingly well-priced too, which isn't always the case with 'green' products.
I was very impressed on opening the box- this is a solid and heavy unit that in fact is attractively designed in appearance.
I have so far used it to charge a motorcycle battery, which it has done very well, but there are multiple uses. Be warned however that its uses are limited only to those types of batteries described above.
The main concern is, as others have suggested, the unreliability of sunshine in the UK. But the product can hardly be faulted for that.
And, being heavy and with its pane of glass, quite fragile...there is an issue with storage. I would recommend you keep the box.
They are easy to use, but I do recommend reading the small manual front to back before using them. If you need more info, their website is also very good, with lots of extra technical explanation of things.
However, I have had mixed and unexpected results, so I’m not entirely certain that one of these changers would get me out of trouble if I needed it.
For example, one morning went to the car, the battery was very low (10V) and wouldn’t turn the starter motor over, the battery was old so I was expecting it at some point. Took the battery out, connected it to the 7.2A charger and turned on. It immediately shot up to 75% charged and within 10min, was at 100% charged and began to trickle charge above 12.6V. The trickle was cutting in and out every minute or so as the battery couldn’t hold the no load voltage. After disconnecting the charger, the battery dropped below 12V in minutes, clearly something wrong, so I bought a new battery. But why did the charger report 100% when the battery was no good?
We use 12V SLA batteries at work and had a few used ones lying about, so I tried some of those. Connected one which was at 12.5V, and the charger kept clicking, same happened with the 3.5A charger. Tried one which was at 7V, and it seemed to charge ok, although the surface temp of the charger got to 60 deg.C which seemed high, but it was sat delivering a constant 7.5 Amps DC; in my opinion too high for the battery I connected.Read more ›
