Can your rechargeable treasure get on the plane?

First, to understand their own charging treasure

There are generally several data on the charging treasure: battery capacity Capacity (mAh), input current (a), output current (a), input voltage (v), Output voltage (v)

The power of the rechargeable battery is mah (mah), which is the product of the current intensity and time, and when the current intensity is in mah (MA) units, the time is measured in hours (h), and the two are multiplied by mah (mah). It represents the time of full discharge under a certain discharge current, for example, 1000 mah when the battery is discharged for 1 hours at 1000 mah.

The relationship between these data can be expressed in one formula:

Charge PO rated energy (Wh) = Rated voltage (V) x rated Capacity (MAH)/1000 or Wh=vxah

Take Millet mobile power 10400mAh as an example

Its output voltage is 5.1V, the rated capacity is 10400mAh, the formula is:

5.1vx10400mah/1000=53.04wh

So it's less than 100Wh . Most of the mobile power supply in the market is less than this rated energy.

Second, what kind of rechargeable treasure can be on the plane

Small series here to teach you a simple three-step, your own rechargeable treasure can be on the plane, a minute to understand!

1, "Three No" or the logo is not completely clear of the charge Bao is not allowed to carry on board

Own production of charging treasure, "three No" charging treasure, no logo or logo identification of the battery charger, even if the capacity of qualified can not on the plane. Again, the scalar is not complete charging treasure, such as only the rated voltage or rated current but not the rated capacity of the charging treasure can not be on the plane.

2, must meet the following data

　　Charging PO capacity less than 20000 mah (mah) and voltage less than 5V

　　The Civil Aviation Authority has stipulated that the portable battery charger rating does not exceed 100Wh (watt hours), and many people cannot find the "Wh (watt Hour)" logo on their own charging treasure. So what is the concept of this data size? Small series with you analysis of this formula, Wh=vxah or wh=vxmah/1000, translated into plain English is: Rechargeable treasure on the logo mAh this piece, the number above the front of 20000,v more than 5, to ensure that the two numbers, you can be unimpeded!

3, rechargeable treasure can take a few pieces?

Under Condition 2 (the upper one), each passenger can carry 2 pieces.

Three, about the charging treasure hot question answer 1, why does the aviation Bureau do not need the power unit to do the limit, must use "The Watt-time" this unit?

Considering that the battery may explode, the strength of the explosion is directly related to the amount of energy, so it is required to set an energy unit to be limited. For example, we can find a 1000 mah battery, although the power is very small, but if the battery voltage up to 200V, so the energy is 200 watts. has exceeded the aviation authority's regulations by a few times.

2. Why does the cell phone use mah as the unit to describe the battery, instead of the tile?

Cell phone Lithium Battery Two units are labeled, just because a lot of people do not understand the concept of tile when not to see, another reason is the cell phone lithium battery 90% is a 3.7V polymer battery, there is no battery between the series-parallel combination, so directly said the power will not cause much error, the other 10% The use of 3.8V polymer, although the voltage is different, but it is only 3.7 and 3.8 difference, the error is small. So it is possible to use mah to describe the battery in mobile advertising.
