Q: How does this \u201cAluminum Air Battery Emergency Power Supply\u201d work? Does it really generate electricity using only water? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A: Yes, this emergency power supply utilizes advanced aluminum air battery technology. When a small amount of liquid (such as water) is injected inside the unit, the liquid promotes a chemical reaction between the aluminum inside and the oxygen in the air, generating electrical power. This power is used to charge devices such as smartphones through USB ports. No prior charging is required.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Q: What type of liquid can be used for activation and how much is needed? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A: It is activated with approximately 80 milliliters (ml) of liquid. It is compatible with a variety of common liquids such as fresh water, salt water, snow melt, river water, sewage, juice, tea, beer, and even urine, greatly reducing the hurdles to securing liquids in an emergency.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Q: You mentioned that the capacity of this power supply is 50Wh, how much is this exactly? How many times can I charge my smartphone? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A: A capacity of 50Wh (watt-hours) is equivalent to approximately 1-3 full charges for a typical smartphone (with a battery capacity of 3000mAh-4000mAh) (varies depending on your smartphone model and battery condition). This capacity is sufficient to ensure a means of communication in an emergency.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A: The output from the USB port is rated at 5V (volts) and 5W (watts) output power. Suitable for charging smartphones, GPS devices, small USB lights, and other small electronic devices that support USB charging.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: If the product has not been activated, it can be stored for 10 years or more (*see the product's instruction manual or specifications for specific years*). When storing, keep the product in its package in a cool, dry place out of direct sunlight, avoiding high temperature and humidity. No special maintenance is required.<\/pre>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
 A: Yes, it is very safe. The reaction process of aluminum-air batteries is gentle and there is no risk of ignition or explosion. They are also environmentally friendly, as they do not contain harmful heavy metals (mercury, cadmium, lead, etc.) and the main products after use are of low environmental impact.<\/pre>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: The product can be operated in a very wide range of temperature environments, from -40\u00b0C to 80\u00b0C. This ensures stable power supply under a variety of harsh conditions, from extremely cold to extremely hot climates.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: Dimensions are approximately 196mm x 67mm x 33mm. The main unit weighs less than 400g, and the total weight after liquid injection is approximately 480g. Compact and relatively lightweight, it is easy to carry in an emergency bag, in a car, or for outdoor use.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: Due to the nature of aluminum air batteries, once they are activated by injecting liquid, they are designed to continue supplying power until the metal inside is consumed, and are basically intended for one continuous use (use-up type). After use, dispose of the product properly in accordance with the instructions of your local government, either as e-waste or as specified.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
