That s where the anker 21w powerport solar charger comes in.
Anker 21 watt solar panel review.
Poweriq delivers the charging speed up to 2 4 amps per port or 3 amps overall under direct sunlight.
As discussed above the results show that models with higher wattage are more effective at charging multiple devices at once.
This is great for camping hiking or fishing.
I strongly suspect that both the anker and aukey solar chargers would have charged at a much higher rate had something more than a 5 smart phone been used.
The cost of a solar panel is dictated by the market price of solar in units of watt.
The big blue anker 21 and sunjack were high scorers as was the goertek 25 000mah.
The anker 21 watt product produced 5 11 volts at 0 52 amps for a total of 2 6572 watts.
They also have a thirty day return policy if you have any issues and will give you a full refund.
After trying such a large range of panels we realized that in this case the larger the wattage makes a big difference after all.

It may sometimes be more economical to purchase two 200w solar panels with higher efficiency ratings as opposed to one 400w panel with lower efficiency.
Review of the 21w anker powerport solar charger.
A larger watt panel means faster charge times less interruption and a more stable supply of power.
This construction makes the anker panels durable and able to withstand the harsh conditions found in the outdoors.
We were impressed by the sunjack s overall power and efficiency in this metric.
