SunJack 15w Portable Solar Charger

For many people, mobile devices have become part of everyday life. I must confess I’m part of this demographic yet I will not confess just how many devices our household has in total.  At work, there are regularly not one but two mobile phones sitting right next to me in addition to the laptop (which I’m typing this on right now).  A lovely white power strip (which I shut off every night) rests peacefully nearby providing me with all the juice I may need on any given day.

There are many instances – hiking, boating, or camping come to mind first – when charging these devices is just not an option.  Enter Sunjack’s 15 Watt Solar Charger + Powerbank assembled right here in the USA (and backed by a one-year hassle-free warranty).

Now, anywhere you choose to go outside you have the ability to charge.  No sun?  Sunjack still has you covered. Its high-capacity power bank will charge your cell phone up to 80% faster than standard chargers — even when the sun isn’t shining.

Sunjack’s solar chargers pump out up to 2 amps of power per USB port (4 amps max with two ports) to provide wall-outlet charging speeds. A built-in smart IC chip intelligently identifies your device and maximize charging speed and protects it from overcharging.

Technical specifications include:

  • Solar panels: 15 Watts of high efficiency mono-crystalline power
  • Max output voltage/current: 5V/2A
  • Battery: 10,000mAh lithium-polymer battery with USB C and Quick Charge 3.0
  • Unit Size folded: 10.5″ x 6.5″ x 1.2″ (26.7cm x 16.5cm x 3cm) – similar to an iPad.
  • Unit Size unfolded: 20″ x 10.5″ x 1″ (50.8cm x 26.7cm x 2.5cm)
  • Unit Weight: 2.1 lbs / 1 kg (battery included)

Whether you are looking to charge your devices on-the-go or add to the ultimate emergency or disaster preparedness kit using renewable energy, Sunjack’s solar charger is a powerful tool (pun intended).
