BX550 is a 5V external battery with maximum 3A high current output ability. Its size is as small as a novel that it will never be too bulky and heavy to take along. With the user-friendly and simple design. This battery can provide extra long runnig time for iPad, cell phones, wireless routers, GPS and many other devices that require 5V power.
It has 5V output voltage
It has 49 Watt-hour ( or 13500 mAh) large capacity
It can output maximum 3 amps electric current *
It can be recharged about 500 times.
It has its own AC charger
It comes with 4 different DC connectors for different devices.
* This battery has 5V constant output voltage, but variable output current. 3A is just the maximum output current this battery can supply. Actual output current will be variable depends on the devices it powered. If the output of a power supply is maintained at a constant voltage, then the load's resistance determines the output current. It is Ohm's Law. So it will be no problem to use this battery to power any device that requires 5V voltage less than 3A current.
How long can this external battery run ?
This battery's capacity is 49Wh(Watt-hour). For your reference, a Alkaline AA battery capacity is around 2Wh ~ 3Wh
Fully charged BX550 capacity is 49Wh. Since this battery can be charged about 500 times, so one
BX550 battery can provides total up to 25000Wh power, equivalent to 8000 ~ 10,000
AA Alkaline batteries.

There will be a symbol with a plus sign on one side and a minus sign on the other with a circle between them. The circle will have an opening so that it looks like a "C". If the opening of the circle is on the side with the plus sign the polarity is positive. If the opening is on the side with minus sign the polarity is negative. If you cannot find a polarity sign on your product you need to call the product's manufacturer to find out what the polarity is.
Part IV. Safety Cautions
|1. Do not subject the battery to extreme pressure.
|2. Do not over charge the battery to avoid shortening of battery life.
|3. Do not immerse in water.
|4. Do not attempt to open or break apart the battery pack.
|5. Do not throw the battery in fire or attempt to burn it.
|6. Keep the battery away from excessively dry or humid environments.
