F.A.Q.

  • Does the SunJack come with a battery?

    Yes! Each SunJack comes with battery pack that gives you power to charge your devices even when the sun isn’t shining.

    If you have your own portable battery, you can also use with the SunJack, but our battery is optimized for maximum charging speed from the SunJack.

  • Can I charge the SunJack battery from a wall outlet?

    Yes! The battery can also charge from any standard micro-USB plug. This is useful if you’re going on a trip and want to have maximum charge with no down-time.

    The battery will reach a full charge in about 5 hours.

  • How Much Power Does 14 and 20 Watts Produce?

    If you look at a standard Apple wall charger (http://store.apple.com/us/iphone/iphone-accessories/power), you’ll see that the small plug is 5 Watts, and the large plug is 12 Watts. The SunJack is more powerful than both of these!

    You want maximum solar power because the rating for a solar panel is only for direct sunlight. This means if it’s cloudy, a 5 Watt solar panel isn’t going to provide enough charge, but our 20 Watt solar panel will still have plenty of juice to spare (allowing for charging even under indirect sunlight or cloudy conditions).

    A Watt is a unit of power, which indicates how much energy can be transferred in a given second. Most solar chargers on the market (with our form-factor and portability) are less than 14 Watts. Most 20 Watt solar panels are not portable – they’re large, heavy, and rigid. And this is the peak power under direct sunlight, which means a 5 Watt solar charger in indirect sunlight may only produce 3 Watts of power – less than a small Apple plug. When it comes to solar, more Watts = more power!

    You can also think of Watts similar to horsepower or CPU speed. You can still get the work done on lower horsepower/CPU speed/less Watts, it will just take longer. With 14 and 20 Watts of solar power, there’s ample power to charge your devices, even with clouds.

    If you’re wanting wall-outlet charging speeds of up to 2 Amps of current, you’ll want as much power as possible. Fortunately with the SunJack, even if there’s no sun you’ll be able to rapidly charge all your devices with our battery.

  • What is special about your USB ports?

    Our solar USB ports provide a full 2 amps of output – which means the 20 Watt SunJack could charge 2 iPads at the same time under direct sunlight!

    Our battery also is able to take in a full 2 amp charge from the solar cells, and discharge a full 2 amps – which allows for very rapid energy storage unlike anything else available.

    Simply put, our USB ports allow for maximum fast-charging of any device.

  • Can I charge directly from the SunJack instead of the battery?

    Yes! Each of the SunJack USB ports provide up to 2 Amps of output, so you can charge directly from the power of sunlight. If it becomes cloudy, simply switch over to the battery for continued charge.

  • What is your solar cell efficiency?

    The efficiency ratio of the solar cell to convert sun light to DC current is approximately 19%, which is higher than average due to using mono-crystalline instead of poly-crystalline solar cells. Here’s a more in-depth article on the difference between mono and poly solar cells: http://bit.ly/mono-vs-poly

  • What’s the difference between thin-film, poly-crystalline, and mono-crystalline solar technology?

    We use monocrystalline solar cells in the SunJack, which are the highest efficiency and longest lasting solar photovoltaics available. Monocrystalline solar panels are typically warrantied for 25 years due to their durability and reliability.

    Polycrystalline is less pure than monocrystalline and has lower heat tolerance, but is cheaper. If you’re installing solar over a large area and spending tens of thousands of dollars, it may be a better option to save with polycrystalline solar panels.

    Thin-Film is the least efficient, usually around 10%, and degrade the fastest, but is the cheapest option, and useful for certain applications where weight and flexibility are critical issues.

  • How durable are your cells?

    Strong enough to be dropped on concrete, stepped and jumped on, and even run over with a car! Check out some durability videos here.

  • Is SunJack waterproof?

    SunJack is weather-resistant, meaning if you leave it out in light drizzle it’ll be fine.  However if you plan to leave it out in heavy rain we recommend purchasing one of our weather-proof sleeves for $5.

About richardhandel

I would like to give a brief snap shot of my life and introduce myself; My name is Richard Handel and was born in 1965 in Suffolk. I have worked as a UK Operation & Intermodule Manager for a shipping company. I live in Hampshire now and am married with 2 young children, both girls so I am a bit outnumbered even the cat is a girl! I have been fishing since I was about 7 years old. I started on small local rivers in Suffolk, then moved onto gravel pits and then carp fishing. My personal best is a 39.08 mirror, over recent years I have started river fishing again, on the Hampshire Avon, this is a nice break from the carp lakes. My life has turned a big corner this year, the company I was working for relocated their Operation centre to Estonia. I was offered a job at the head office in London. This would have meant a 5 day commute and working in Stratford. As a family, we did not fancy this, as I would hardly spend any time with the children (and the Mrs). So after 22.5 years, I was given a nice redundancy package and with my wife is working full time. I became the house husband. This has meant a complete turn around in my fishing, as I can pick and choose when I go. I have found a splendid new syndicate to fish this year, which includes 5 lakes and some 8 miles of river with only 150 members. It's an amazing change to the way I am able to fish. I am now trying to start my own tackle business and make a bit of a name for myself in the world of fishing, as I have retired from real work. Richard
