Why use a POWER 50?

The POWER 50 can charge almost any mobile device from laptops to video cameras to MP3 players and mobile phones.

One of the most common question our team receive is, "How do I charge my laptop directly from a solar panel?". While it is most often fine to charge smaller electronics directly from solar panels, when it comes to laptops the simple answer to this is, "You don't!".

A laptop typically need a current of 3 to 5 Amp to run which equals 60 to 100 Watt of continuous solar power. The problem is that the solar output will fluctuate so in reality laptop will need 80- 120Watt of if connected directly to solar power. With this a new problem arises - the risk of supplying to much current to the laptop charger and thus potentially harm your device.

With the Power 50 you can use less solar power and safely charge ALL your devices, from mobile phones and MP3 players to laptops.

The Power 50 is extremely light weight (due to the Polymer Lithium technology) and compatible with most solar panels.

The Power 50 is built around Polymer Lithium Ion batteries, a new battery technology that provides lighter and tougher batteries than Lithium Ion batteries.

The Power 50 is the most versatile mobile battery on the market, with multiple input and output possibilities.

Lithium Polymer technology is much safer than older Lithium Ion technology.

Triple charging ways: travel / car / solar

Dual independent output though 5 V USB or 5-19V DC.

The Power 50 has "Pass through charging" technology that charges both the Power 50 and connected devices in one charge.

What solar power should be used with POWER 50?

The HumanEdgeTech team recommend Solar Blazt FEATHER or SURVIVOR http://www.humanedgetech.com/shop/home.php?cat=4 to be used with the POWER 50.

The FEATHER series represents the lightest (weight/watt) solar panels on the market and folds tight for easy storage in pockets, backpacks etc. The FEATHER is recommended for mountaineering, trekking and similar activities.

The SURVIVOR series has a waterproof coating and is recommended for water related activities as well as polar sledge hauling. The FEATHER is water repellant, but the SURVIVOR is water proof and more able to withstand long periods of constant exposure to elements.

How many WATTS do I need for my solar panel?

All the panels in the Solar Blazt series from 5 Watt up to 30W can be used to charge the POWER 50. You can daisy chain several panels to increase the Watt. It is possible to connect more than 40Watt (up to 100Watt) of solar power but it will not make charging faster.

To figure out how many watts you need (and if you need extra batteries) is a simple procedure. Check the wattage consumption of the gear you want to charge (app. 30-80W/hour depending on size for a laptop) and multiply with planned hours of usage.

Example: You use one of the small ASUS EEE Expedition laptops provided by HumanEdgeTech. The power usage is app. 25W/hour and you plan to use the laptop for 2 hours per day a total of 50Watt. You are also using a satellite phone for one hour calling and 5 hour standby which will require 5 Watt total. You also plan to use an iPOD for 5 hours a day which typically uses 0.5Watt/hour of playtime. That add another 2.5Watt. Total expected consumption is 53Watt/day. A FEATHER or SURVIVOR 20Watt would provide this charge in app. 3 hours /day in perfect conditions.

Conditions are seldom perfect (full sun, hitting solar panel 90 degree angle) so unless you are prepared to skip the laptop work when weather is bad, you might want to up to 40Watt or maybe even add an extra POWER 50.
