We received the Sunjack with high expectations as their competitor GoalZero fail to deliver.
There will be always a battle when comes to technology, but selling a product that doesn’t perform when you need it can be dangerous. Luckily the Sunjack did what suppose to when was needed without much tweaking or hesitation.
For a second let’s talk about mAh. (Milli Ampere Hour)
A milliampere hour (mAh) is 1000th of an ampere hour ( Ah ). Both measures are commonly used to describe the energy charge that a battery will hold and how long a device will run before the battery needs recharging.
Solar panels: 14 watts of high efficiency mono-crystalline
Max output voltage/current: One 5V/1.5A USB port
Battery: 8,000mAh lithium-polymer battery ~ 5 hours
Unit Size folded: 9″ x 6.5″ x 1.75″ (23cm x 16.5cm x 4.5cm) – similar to an iPad.
Unit Size unfolded: 9″ x 31″ x 1″ (23cm x 79cm x 2.5cm)
Unit Weight: 1.75 / 0.8 (lbs/kg)
Packaging Dimension: 10.5″ x 8.5′ x 2″ (27cm x 22cm x 5.1cm)
How many charges can you get of the panel once fully charge?
If you are using an iphone 6 or similar their battery requires 1800mAh per charge, so safely you can count in 3 full charges while using the solar panel.
We recommend of course not to drain your cellphone battery completely because will take longer to get an optimal charge.
While not using it, set your phone on airplane mode and stop all running apps.
The sunjack overall is an easy set up, bulky and heavy but perfect to use in a thru hike; and does not require clear skies to function.
The rugged constructed casing and waterproofness allows you to clip it to your pack while hiking. If you are bushwacking, scrambling, passing through a storm or in the heat of the summer the sunjack delivers.
For shorter hikes an ancher 10000mAh is a better solution at 9oz of weight.
In our opinnion sunjack has deliver a high qualify functioning solar panel that will provide enough power for 2 people and multiple techy items with a super affordable pricepoint.
