The Weza is a versatile, robust energy source providing totally dependable power for emergency situations and everyday use in remote applications. The Weza features an internal rechargeable non-spill 12V, 7Ah lead-acid gel battery capable of jump-starting a range of vehicle engines, as well as powering a wide range of other devices. Very portable at 18.6 lbs.
Unlike similar power packs, in emergency situations, or when power is not available, the Weza can be energized using only your legs by stepping on the innovative foot treadle. Depending on the effort applied, this creates electrical energy of 25 to 40 Watts. 
The Weza can also be charged from AC or DC power. It is supplied with an AC adapter that can be plugged into a standard AC wall outlet (110V to 240V) and recharges the internal battery in about 8 hours. A DC charging cable is also included that charges from a vehicle's cigarette lighter socket. The Weza can also be charged from any other DC source that provides 13V to 21V, such as wind or solar.
The Weza has foldable stabilizer arms, making it easily portable and able to be stowed neatly, ideal for boats, motor homes and campers. Included with your purchase is a sturdy nylon bag with a waterproof rubberized base, storage pouches and reflective strips allowing easy 
portability and safe storage of the Weza and accessories.
Included in the bag is a pair of heavy-duty jumper cables and a small service tool kit allowing field maintenance of the Weza. A truly portable, power independent energy source, the Weza provides meaningful power anytime, anywhere.

FAQ
How long is the warranty?
The product has a 2-year warranty.
Can the Weza's internal battery be replaced?
Yes, please consult your service manual or contact the Freeplay Customer Support Center for advice.
I have a regular 5 Amp battery charger with crocodile connector clips, can I use it to charge the Weza through the terminal posts?
Yes.
How do I know when the Weza is fully charged?
Read all recharging instructions in the user manual. The lights on the display bar indicate charge level.
What products can my Weza power or recharge? Most products compatible with a 12V DC power source. Is using the Step Input the only means to charge my Weza? No. The Weza can also be charged from either a DC or AC power source. How long will it take to charge my Weza from the wall socket with the AC adapter? It will take approximately 8 hours to fully charge the Weza.
Can I charge my 12V DC device while the Weza is being charged either through the DC input or via the crank?
Yes.
What materials are used in the Weza and are they recyclable?
The casings are made of polypropylene and glass-filled nylon. The transmission is made of a combination of acetyl, glass-filled nylon and aluminum, while the input levers, pedal and stabilizer arms consist of a glass-filled nylon. All plastic materials used are thermoplastics and can be recycled. The Weza contains a non-spill lead-acid gel battery, which needs to be recycled according to regulations established by your local authority. Please consult your user manual or contact the Freeplay Customer Support Center for more advice.
How long will a fully charged battery retain its charge?
The battery will self-discharge at 5% per month when the unit is stored at a temperature of 20 degrees Celsius (68 degrees Fahrenheit). The self-discharge rate increases with an increase in ambient temperature.
Will I damage the Weza if I crank the pedal too fast?
No, the faster you crank the more energy you store in the internal battery.
Can I over-crank the unit - does it ever stop you from cranking?
No, you cannot over-crank the internal mechanism. It consists of a simple gearbox, which drives an alternator, providing power to the internal battery.
What type of rechargeable battery is used in the Weza?
The Weza has a 12 Volt, 7 Ampere-hour, non-spill lead-acid gel battery.
Can I leave my Weza charging from an AC wall charger all the time and unplug it when I need to use it?
No, the Weza should not be left on charge for longer than 24 hours.
Should I discharge the Weza's internal battery before recharging?
No. The Weza contains a non-spill lead-acid gel battery, which does not require total discharge before recharging. Leaving a lead-acid battery in a fully discharged state for an extended period of time will cause damage to the battery and limit its life.
Why is it named Weza?
Freeplay Energy plc is committed to a world of responsible energy. This commitment extends beyond the environmental impact mitigation of our products to the sustainable provision of energy in developing communities and humanitarian initiatives. The names we choose for our products tell some of our stories:
Weza is a Swahili word that means “power” – to be empowered, enabled and in control. According to the World Bank, 24% of the urban population and 67% of the rural population in developing countries are without electricity. The exact number of people who lack direct access to electric lighting is unknown. However, most estimates put the value at approximately 2 billion people.
Energy is crucial to reducing poverty and hunger, improving health, increasing literacy and education, and improving the lives of women. However, the vast majority of the poor is dependent on traditional primitive fuels – wood, dung and crop residue. For many, these energy sources barely allow them to fulfill the basic human needs of nutrition, warmth and light, let alone the possibility of harnessing energy for productive uses, which may help them to end the cycle of poverty. The link between poverty and energy consumption is clear: the areas in the world that have the highest levels of poverty also have the lowest levels of energy consumption. In sub-Saharan Africa, where more than half of the population lives below the poverty line, energy consumption is a staggering 20 times lower than the global average; 113 kWh compared with a global average of 2465 kWh.
Amid continuing political challenges, economic hardship and disease, lack of reliable energy remains a primary obstacle to poverty eradication, which is most prevalent in rural areas. However, the transmission and distribution costs of extending grid electricity to dispersed rural communities, where some 2.8 billion people in the world live, are high. Decentralized energy technologies are thus the only immediate and effective solution.
