Test Data and Operating Instructions

The 400 Watt Crank-a-Watt™ Version

Please note! The Crank-a-Watt™ system will shut of automatically, if the battery voltage drops below 12.0 volts. This is to protect the battery from damage. From that point, to recharge a dead battery, it will take less than 20 minutes cranking by hand, and only 10 minutes if using a bike. This is cumulative. In other words, you can do a little cranking at a time, until 20 minutes is achieved. There is very little physical effort needed. It's a very powerful generator.

Overview

Product: Crank-a-Watt™ Patent pending emergency generator. Test reviewed practical uses for the 400 watt hand crank/bike pedal unit. This independent testing proves the Crank-a-Watt™ hand/bike pedal generator product is an "Extremely valuable asset during a power outage or emergency."

NOTE: The Battery was cranked to a full charge before each test to get best results. When idle, the battery may be kept at peak readiness by using a float charger. Recharging the battery with a bike pedal setup will require approx. 50% less physical effort than hand cranking, and will recharge the battery 2 times faster than hand cranking.

Test #1 Using: Small lead acid battery 145 cold crank amps, lawn mower-tractor type (12v) (this is the type of battery supplied with your unit). A 400 watt inverter was used for this test.

Test #2 Using: Larger lead acid battery 240 cold crank amps, lawn mower-tractor type (12v) (this is the type of battery supplied with your unit). A 1500 watt inverter was used for this test.

Important Note: All test data was collected using one standard lead acid, lawn and tractor battery. The performance of the Crank-a-Watt™ product will double if using 2 batteries, triple if using 3 batteries, and so on. Adding additional batteries is a simple, and cost effective way to greatly boost the running time of your appliances. An inexpensive set of jumper cables can be used to connect extra batteries to the Crank-a-Watt™ unit.

    No cranking needed.
  5. Charged 1 cell phone and 1 I pod. 6 watt combined load. Test started at 12.8v. Charged for 20 minutes, Final battery charge 12.7v
    Did crank a few times
  6. Electric can opener. Test started at 12.8v. Operated for 20 seconds.
    Battery Voltage did not drop
  7. Recharged AAA batteries (to full charge) with rechargeable battery charger. Load (na). Duracell, ray-o-vac, energizers etc..) Recharge time 30 min.
    Cranked a few times
Crank-A-Watt Police and Fire version
  1. Recharged batteries for cordless drill, starting at dead drill battery stage. 22 watt load. Started with 12.7v. Test took 1 hour. 
    Cranked frequently to keep battery from going down.
  2. Operated T.V. 37". 75 watt load. Started with 13v. Test lasted for 2 hours. Final battery voltage 12.3v.
    Cranked frequently to keep battery from going down
  3. Operated PlayStation and T.V. 275 watt combined load. Test started at 13v. Test lasted for 1 hour.
    Final battery voltage 12.3v Cranked frequently to keep battery from going down
  4. Operated Laptop Computer. 65 watt load. Test started at 12.8v. Test lasted for 45 minutes. Cranked a few times

Test #2- Using 240 CCA Battery and 1500 watt power inverter:

  1. Bread Maker: 500 watt load: Test started at 13v. Test lasted for 6 min. Final battery voltage 12.6v. Cranked a few times
  2. Waffle Maker: 650 watt load. Test started at 13v. Test lasted for 10 min. Final battery voltage 12.5v. Cranked several times
  3. Black and Decker Drip Coffee, 12 cup: 975 watt load. Test started at 13v. Test lasted for 10 min. Final battery voltage 12.2v. Cranked continuously
  4. Toaster: 800 watt load. Test started at 12.8v. Final battery voltage 12.5v. Cranked quite a lot, but not continuously
  5. Double Burner Hot Plate: This is set up so you can use a smaller burner (600 w) or a Larger Burner (900 w).
    Smaller burner:Test started at 13v. Test lasted for 30 minutes. Final battery voltage 12.2v
    (Cranked continuously when using the Large Burner, and we were able to cook on it)
    You can only use one burner at a time with 1 Large Battery.

NOTE: The Battery was cranked to a full charge before each test to get best results. When idle, the unit may be kept at peak readiness by using a float charger. Recharging the battery with a bike pedal setup will require approx. 50% less physical effort, and will recharge the battery 2 times faster than if hand cranking.
