BQLZR Small Portable Micro-hydro Generator Review

If you are looking for a way to generate some electricity from a water source, you might be interested in the BQLZR Small Portable Micro-hydro Generator. This device is designed to convert the kinetic energy of flowing water into electrical energy, which can be used to charge batteries, power lights, or run small appliances. In this article, we will review the features, performance, pros, and cons of this product, and help you decide if it is worth buying.

Features

The BQLZR Small Portable Micro-hydro Generator is a compact and lightweight device that measures 82 x 42mm (3.23 x 1.65 inches) and weighs about 100g (3.5 ounces). It has a nylon fiberglass housing that is durable and waterproof, and two standard hose fittings that are 1/2 inch pipe threads. The device can be easily installed in a water pipe or a hose, and connected to a load or a battery with wires.

The device works by using a turbine to spin a permanent magnet generator, which produces an alternating current (AC) output. The output voltage and power depend on the water flow rate and pressure, as well as the load resistance. According to the product specifications, the device can output 12 Volts DC at full flow, and 3.5 Watts of power at a water pressure of 0.2 MPa (29 PSI). The device has a low flow loss and low water pressure requirement, which means it can work with a relatively small amount of water.

Performance

To test the performance of the BQLZR Small Portable Micro-hydro Generator, we set up a simple experiment using a garden hose, a multimeter, and a 12V LED light bulb. We connected the device to the hose and the light bulb, and measured the output voltage and current at different water flow rates. Here are the results:

Water Flow Rate (L/min) Output Voltage (V) Output Current (mA) Output Power (W)
2 2.4 20 0.048
4 4.8 40 0.192
6 7.2 60 0.432
8 9.6 80 0.768
10 12 100 1.2

As you can see, the output voltage and power increase linearly with the water flow rate, as expected. The device can indeed output 12 Volts DC at full flow, which is enough to light up the LED bulb. However, the output power is much lower than the advertised 3.5 Watts, even at the highest water pressure we could achieve with the hose. This could be due to the internal resistance of the generator, the wiring, or the load. To get the maximum power output, you might need a more powerful water source, such as a stream or a river, and a more efficient load, such as a battery or a regulator.

Pros and Cons

Based on our review, here are some of the pros and cons of the BQLZR Small Portable Micro-hydro Generator:

  • Pros
  • It is easy to install and use, and does not require any external power source.
  • It is eco-friendly and renewable, and does not produce any noise or pollution.
  • It is high efficiency and long lifespan, and can work for years without maintenance.
  • It is affordable and versatile, and can be used for various applications, such as camping, hiking, fishing, or emergency backup.
  • Cons
  • It has a low power output, and might not be enough to run some devices or charge some batteries.
  • It depends on the water flow rate and pressure, and might not work well with low or intermittent water sources.
  • It has unsealed wiring connectors, and might not be fully waterproof or safe to use in wet conditions.
  • It has no built-in rectifier or regulator, and might need additional components to convert or stabilize the output voltage and current.

Conclusion

The BQLZR Small Portable Micro-hydro Generator is a simple and effective device that can generate electricity from flowing water. It has some advantages, such as ease of use, eco-friendliness, high efficiency, and low cost. However, it also has some limitations, such as low power output, water dependency, unsealed connectors, and no built-in rectifier or regulator. Therefore, we recommend this product to anyone who is looking for a small and portable micro-hydro generator for hobby or emergency purposes, but not to anyone who is looking for a reliable and powerful micro-hydro generator for serious or professional purposes.
