SSD-30W DC28V Output Portable Manual Generator Hand Crank Generator Emergency Power Supply for Storage Battery Charging

SSD-30W DC28V Output Portable Manual Generator Hand Crank Generator Emergency Power Supply for Storage Battery Charging

Description:
- This product is a portable hand cranked emergency power supply that can generate electricity and be charged. In any corner of the world where there is no electricity or oil based power generation, manual power can be used to supply various electronic products. It can be actively applied in activities such as field operations, field investigations, rescue operations, natural disasters, survival training, emergency communication, long-term power shortage, tourism, and emergency electricity use. Mainly supplying power or charging for portable products such as low-power communication radios, walkie talkies, laptops, PDA, mobile phones, cameras, digital cameras, music CDs, MP4, MP3, portable mobile TVs, DVDs, radios, flashlight lighting, various lamps, electric tools, and various measuring instruments. It can directly charge various types of batteries such as lithium batteries, nickel argon batteries, lead-acid batteries, etc.

Function:
- The whole machine has an output power of 10W-30W.
- Output voltage of 0-28V, and can be adjusted according to the electricity voltage (need a DC to DC Converter, which is not included).
- It has efficient and fast power generation ability.
- Hand cranked power generation, green and environmentally friendly, allowing electricity to be in your fingertips anytime, anywhere.

Features:
- This product adopts high-tech magneto electric conversion technology, which has the advantages of small size, high power, and high efficiency.
- The shell is made of high-strength aluminum alloy composite material, which is lightweight, sturdy, durable, and easy to carry.
- The circuit adopts a wide range of output voltage, suitable for charging all electrical batteries ranging from 0-28V.
- The charging method adopts the most efficient pulse charging method, fully activating the battery and extending its lifespan and protecting it.
- Equipped with overheat and overcurrent protection functions.
- Waterproof, this machine has a general rain protection function.
- Hand crank speed requirement: the hand crank speed should be between 60-120/hour.

Precaution:
- Before using this product to charge other devices, please carefully read the instructions for using this device and understand whether it is suitable for use with this product.
- Devices that are not suitable for use within this voltage and current range are prohibited from using this product for charging or power supply to avoid damage to the equipment or accidents.
- When connecting the output cable to the charged device, be sure to correctly connect the positive and negative poles to avoid damage to the device.
- When operating this product, please note that the hand crank speed should be within the normal range (120 rpm) and should not exceed the speed limit to avoid damaging the machine.

Advantages of Use with DC Converter:
- It is very convenient, with 12 voltage levels adjustable at any time, making it easy to use on various devices.

Defects in Use with DC Converter:
- Reduced power generation efficiency and high energy consumption. (After the first level of voltage regulation by the built-in circuit board of the generator, the power generation efficiency is only 90%. After the second level of voltage regulation by the DC converter, it is also 90%, so the overall power generation efficiency is only 80%.)
- Improper user operation, such as inaccurate voltage setting, is highly likely to damage electrical appliances.
- If the converter is damaged due to poor storage and is not detected, reckless use may cause electrical damage.

Note:
- DC-DC converter is not included, please contact our customer service if you need it.
- When using a DC-DC converter for power generation, if it feels particularly difficult to manually shake, please make sure to stop generating electricity and look back to see if the overall circuit connection is normal and if the voltage matching of the converter is normal.
