While on the floor, they have to remain as “light” as you possibly can, carry just the most important gear, yet remain mobile, functional, in communication, and also have causes of artificial light if needed.
MW, certainly one of several fire jumpers, was searching for any lightweight and sturdy way to power the portable electronics he must use throughout his frequent fire-fighting missions in remote parts of southeastern California. His electronics are operated by rechargeable AA, AAA, and CR123 batteries, and can include a 5-watt xenon Brought flash light, teams of Midland 16 mile radios with NOAA alert, an ipod device with speaker pier, a Gps navigation, a golf rangefinder, along with a camera. In the past, once the batteries in a single device exhaust power, batteries in one device are switched to a different, and recharging must hold back until he’s came back for an automobile or perhaps an AC power outlet. During prolonged fire-fighting missions, losing power because of discharged batteries is inconvenient and potentially harmful for that group. To prevent lack of power, most of the fire jumpers carry multiple teams of extra batteries, which adds weight for their already heavy payload. Battery charger he makes use of in your own home is made of a quick charger by Energizer that may recharge four batteries in fifteen minutes, and isn’t available.
MW contacted Powerenz to inquire about when we could design a custom portable solar energy system that will permit him to recharge his AA, AAA, and CR123 batteries when needed within the field for prolonged amounts of time. He needed a method that will:
a. utilize solar power for fuel, together with a portable solar power,
b. be stored and transported inside a durable bag that may be transported with a handle, shoulder strap, like a fanny pack, or mounted on any MOLLE-compatible backpack or vest,
c. be light-weight for lengthy hauls,
d. be billed by Electricity or AC power when available,
e. produce AC power for his fast AA/AAA charger, if preferred,
f. produce Electricity power for any mobile Electricity-powered charger that will recharge his small batteries during fire-fighting missions,
g. produce solar USB power for USB-powered devices along with a solar mobile phone charger when needed,
h. provide durable, lengthy-term independence in the power company, and
i. be silent.
A transportable solar power-battery system was put together that incorporated the next components:
a. reliable, safe, 11.1-volt, 4.24 amp-hour, very lightweight lithium battery power with lightweight enclosure/bag,
b. 5-10-20-watt very lightweight, folding, portable solar power that continued to be outdoors the bag,
c. small lightweight solar charge controller,
d. 120-watt Electricity-AC power inverter for that AC-powered battery fast charger,
e. 12-volt female Electricity socket for any Electricity-powered device,
f. a USB adapter to be the USB solar charger,
g. proper fusing and wiring, and
h. MOLLE-compatible deployment pack in user-selectable color/camouflage.
The ability system could deliver no more than 88 watts of capacity to the Electricity port and inverter for brief lengths of your time, 20 watts as lengthy as 2 hrs, and it was wired, fused, and digitally protected accordingly. With respect to the exact components incorporated, the whole system considered between 3 and 4 pounds. In good sunlight, it might take 3-4 hrs for that solar power to charge the battery again from empty to full, with respect to the power the solar power. Obviously, the machine enables you to recharge MW’s smaller sized batteries once the system battery is under fully billed. There’s a USB adapter that plugs into the cigarette lighter socket, and it has two standard female Type A USB charge ports, one which provides 1 amp of current, and yet another that gives 2.1 amps of current for MW’s power hungry iPhone, iPad, Tablet, or any other USB-billed device. If MW needed added protection against damage, dust, or water, this same system might be enclosed inside a waterproof hard situation.
The portable solar energy system forces in the AA/AAA/CR123 charger quietly and frequently while on the run. Keep, the portable product is stored with the rest of the fire-fighting gear , and trickle-billed utilizing an AC-powered charger until it’s needed again.
