充电宝能不能上飞机（转帖）

闲云野鹤

中国的航空公司要求：

一、看懂自己的充电宝

　　充电宝上一般会有这样几个数据：电池容量Capacity（mAh）、输入电流（A）、输出电流（A）、输入电压（V）、输出电压（V）

　　充电电池的电量都是毫安时（mAh），为电流强度与时间的乘积，当电流强度用毫安（mA）作单位，时间用小时(h)作单位，它们两个相乘就是毫安时（mAh）。其表示在一定的放电电流下完全放电的时间，例如，1000毫安时指此电池在1000毫安的电量下可放电1小时。

　　这几个数据之间的关系可以用一条公式来表述：

　　充电宝额定能量(Wh)=额定电压(V)×额定容量(mAh)/1000或Wh=V×Ah

　　以小米移动电源10400mAh为例，它的输出电压为5.1V，额定容量为10400mAh，套用公式为：5.1V×10400mAh/1000=53.04Wh，所以是小于100Wh的。市面上大多移动电源都小于这个额定能量。

　　二、什么样的充电宝可以上飞机

　　小编在这里教你简单的三小步，自己的充电宝能否上飞机，一分钟就搞明白！

　　1、“三无”或标识不全不清楚的充电宝 禁止携带登机

　　自己制作的充电宝、“三无”充电宝、没有任何标识或标志标识不清楚的充电宝，即使容量合格也不可以上飞机。再有，标量不齐全的充电宝，例如只有额定电压或额定电流但是没有额定容量的充电宝也不可以上飞机。

　　2、必须满足以下几项数据

　　充电宝容量小于20000毫安时（mAh）且电压小于5V

　　民航局规定随身携带的充电宝额定能量不超过100Wh（瓦特小时），很多人在自己的充电宝上找不到“Wh（瓦特小时）”这个标识。那么这个数据大小是什么概念呢？小编带你分析一下这个公式，Wh=V×Ah或Wh=V×mAh/1000，翻译成大白话就是：充电宝上标识mAh这块，前面的数字别超过20000，V前面的数字别超过5，保证了这两个数字，你就可以畅行无阻啦！

　　3、充电宝能带几块？

　　在满足条件2（上面那条）的前提下，每位乘客可以携带2块。

　　三、关于充电宝热点问题的解答

　　1、为什么航空局不用电量单位做限制，非要用“瓦时”这个单位？

　　考虑到电池可能会爆炸，爆炸效果的强弱直接和能量多少有关，所以要规定一个能量单位做限制才行。比如我们可以找一个1000毫安时电量的电池，电量虽然很小，但如果电池的电压高达200V，所以能量上就是200瓦时。已经超过了航空局规定的一倍了。

　　2、为什么手机用毫安时这种单位来描述电池，而不用瓦时？

　　手机的锂电池两种单位都标注，只是因为很多人不懂瓦时的概念不去看，另外一个原因是手机锂电池90%都是3.7V的聚合物电池，不存在电芯间的串并联组合，所以直接说电量不会造成多大误差，另外10%采用的是3.8V的聚合物，虽然电压不同，但也仅仅是3.7和3.8的区别，误差不大。所以手机宣传中沿用毫安时来形容电池是可以的。

加航要求：（Air Canada）

Batteries and Personal Electronic Devices

The acceptance and packaging rules below apply to:

• Personal electronic devices (PEDs), including cameras, mobile phones, drones, laptops, tablets and camcorders.
• Spare cells or battery packs normally used for camera equipment, mobile phones, drones, power tools, power banks, etc.
  

Watt Hours

Watt hours (Wh) are calculated by multiplying voltage (V) by ampere-hours (Ah):

• Volts x Amps = Watt Hours (Wh)
  

Battery Safety

All cells and battery packs must be individually protected to prevent short circuits, e.g.:

• Exposed terminals can be taped over.
• Individual cells or battery packs can be in their original retail packaging or stored in a protective pouch or case, or a separate plastic bag.
  

Maximum Quantities

Each passenger may bring maximum quantities as follows in carry-on baggage only*:

(PEDs) Containing Cells or Battery Packs	Maximum 15 devices
Spare Cells or Battery Packs	Maximum 20 spare cells/battery packs. Of these 20, no more than: 2 lithium ion batteries with a rating of 100 but not exceeding 160 Wh 2 sealed lead acid (SLA) non spillable batteries with a maximum rating of 12 volts / 8.3 Amps (100 Wh)

Exception - Only the following devices are permitted in or as checked baggage:

• Electric toothbrushes and/or shavers
• Large medical devices, such as a portable kidney dialysis machine.
  

Lithium Metal Cells and Battery Packs

The following are permitted in carry-on baggage only*:

• Personal electronic devices containing lithium metal cells or battery packs with a maximum lithium metal content of 2 grams or less.
• Spare lithium metal cells or battery packs with a maximum lithium metal content of 2 grams or less.
• If the cells or battery packs are removed from the device and carried on board, the device can remain in checked baggage.
  

Lithium Ion Cell Battery Packs - with a rating of less than 100 Wh each

The following are permitted in carry-on baggage only*:

• Personal electronic devices containing accepted lithium ion cells or battery packs with a rating of less than 100 Wh each
• Spare lithium ion cells or battery packs with a rating of less than 100 Wh each
  

If the cells are removed from the device and carried on board, the device can remain in checked baggage.

Lithium Ion Batteries - with a rating of 100 but not exceeding 160 Wh

• One battery can remain installed on the device (e.g. video camera).
• A maximum of two (2) individually protected spare lithium ion batteries with a rating of 100 Wh but not exceeding 160 Wh may be carried per passenger in carry-on baggage only*, pending approval by Air Canada airport agents.
  

Alkali-manganese (alkaline), Zinc-carbon (dry cell), Nickel Metal Hydride (NiMH), Nickel Cadmium (NiCd) and Silver Oxide Batteries

• Devices containing these types of cells or spare cells are permitted in carry-on baggage only*. If the cells are removed from the device and carried on board, the device can remain in checked baggage.
  

Sealed Lead Acid (SLA) Non Spillable Batteries

• A maximum of two (2) sealed lead acid (SLA) non spillable batteries with a maximum rating of 12 volts / 8.3 Amps (100 Wh) are permitted in carry-on baggage only*.
• Devices containing these types of batteries or spare batteries are permitted in carry-on baggage only*. If the battery is removed from the device and carried on board, the device can remain in checked baggage.
  

* On smaller aircraft (e.g. Jazz Dash-8 or CRJ) with limited onboard storage space, you’re asked to deposit your carry-on items on a Skycheck cart as you board the plane. Battery-powered devices Personal electronic devices containing batteries and spare cells or batteries must always be removed from carry-on baggage that is deposited on such carts and must carried into the aircraft cabin.
