The initial charging is crucial to the battery performance of the product.
When charging for the first time, plug your new Discover 300 into an AC
outlet until fully charged.
How to use the product:
·Low temperatures can impact both the battery capacity and the output power.
·It can power your devices at temperatures ranging from 32℉~104℉(0℃~ 40℃).
·If the product is charged at a temperature below 32℉(0℃), we suggest it be
placed in a dry and insulated environment.

FAQs
12
Q1: What type of battery is in the product?
A: This product uses a power cylindrical 18650 lithium-ion battery.
Q2: How do I know whether the product is well charged?
A: Check the battery level by pressing the capacity button on the LCD.
Q3: Can it charge and discharge simultaneously?
A: Yes, but it is not recommended to charge and discharge at the same time in
order to protect the battery life. It is OK to use the product even when it’s not fully
charged.
Q4: Can l take the product onto a plane?
A: No. Since the product contains a large volume of lithium-ion batteries with a
maximum power capacity of 300Wh, it is deemed as a dangerous article and not
allowed on planes under FAA regulations.
Q5: How long will the product run my device?
300Wh*0.8/operating power of your device = the actual working time.
The calculation formula is:
the maximum power capacity of the product*the conversion efficiency of the
product/operating power of your device. For example, by the output of the product
with a maximum power capacity of 300Wh. your electronic device with a rated
power of 100W can continuously run for 2.4 hours (300/100*0.8=2.4).
Note: 0.8 represents the conversion efficiency of the product, because the
product will lose a small amount of energy during discharge.
