Solar Charger for GoPro – UpdateBy Jeff Crystal
In a previous post, we showed how you can charge GoPro Hero cameras from our solar chargers. Since this is such a popular device to charge, we did a bit more testing and discovered that you can charge a GoPro Hero direct from one of our 6Volt, 2.0 or 3.4 Watt solar panels. The model we tested had a 4 Watt hour battery so it would take about 5 hours from a single 2 Watt panel to charge in direct sunlight, about 3 hours from the 3.4 Watt panel (there are several loss factors in charging we go through in our tutorial).
In addition to the panel, you’ll also need our Female 3.5×1.1 MiniUSB adapter to connect from the panel to the GoPro.
The advantage of this approach is that it is cheap and you don’t have to worry about waterproofing anything as the panels are waterproof and nearly indestructible. The downside is that you don’t have a battery reservoir so this solution only works in direct sunlight. If you have one of our solar chargers like the Fuse 4W, you can charge from the battery or direct from panels at your option.
Techy note: the Hero does have a blocking diode so a shaded panel won’t pull charge back from the Hero.
