Is a UPS in CARRY ON okay?:

There are threads about checking a UPS into checked baggage, but has anyone tried to successfully carry one on? I'm taking Frontier and don't wanna pay to check a $30 UPS.....

It will be up to the TSA agent:

UPS is not the issue. What type of battery and what size. You can see TSA and F9 requirements on their respective websites. Very unlikely that you will have an issue with a standard external battery used to charge a mobile phone. But, again, the details of the battery matter.

To be clear, it is not "up to the TSA" Officer. Rather, TSA rules do govern.

UPS batteries normally are non-spillable lead-acid, not lithium-ion. They aren't restricted.

As the post above me says, most UPSes used to lead acid but today there are Lithium ones. Those are way, way above legal limit. Consider the biggest phone/laptop external battery you can carry on is ~1lbs and most of that is the LiOn cells themselves. Most of a desktop UPS is again the battery (75-80% at least) and they are much heavier than a pound or two.

There are two parts of the carry on battery rule:
The type of battery, whether it is banned, restricted to a certain capacity or allowed.
If they are the restricted type, then you would need to see if they are within the capacity restriction.
Most APC UPS will have these on the label.

However, the wildcard is whether the TSA agent is wise enough to understand these rules and apply them.

Do not plan your travel around what some random TSA Officer might or might not do. Yes, there are occasions when they make the wrong call. But, if it is down to something which matters -- and it would here -- then ask for a supervisor. They have the capacity to pull up their policy as well as the public-facing website.

If it is something odd-ball, it does not hurt to have a printed copy of the TSA website covering the issue.

It is easy to correct an error without getting into the sneering put downs which wind up as problems.

The thread has taken a TSA turn, so we'll move it to the Practical Security forum.

If you do decide to do this, I'd suggest disconnecting the batteries, and on the smaller units, taping the battery terminals. Quality units usually have a physical disconnect switch/plug on the back of them. While lead-acid batteries aren't anywhere near as bad as LiIon batteries in acting badly, it still can happen. Likewise, you don't want the UPS randomly turning itself on while it's in an enclosed space and overheating. Fire on an aircraft is a very bad thing.

I've never seen a disconnect switch. Every remotely modern UPS I've dealt with has a plug in the cable coming off the battery and it's behind a panel so it can't be plugged in by accident. A switch could get bumped.

thanks - sorry for the late reply - didn't realize i didn't have email subscriptions not enabled...>.<

since i'm "new" i can't apparenly post the link to the TSA website, but if you google "tsa non spillable wet batteries" then it's the first post that comes up; below is the contents of that webpage...

"Non-Spillable Wet Batteries
Carry On Bags:
Yes (Special Instructions)
Checked Bags:
Yes
No more than two spare non-spillable wet batteries are allowed as long as each battery does not exceed 12 volts and 100 watt hours."


per the above it seems like a non spillable wet battery (this is an AGM battery) such as the one in the ups would be allowed w/ restrictions, which is why i need to know the watt hours


i chatted w/ APC regarding the unit, and below is the chat transcript; as i don't see the watt hours anywhere on the battery

i'm at a loss - this a BN450M APC Back UPS (450VA/255 watt) unit, but again, the unit has no watt hours printed anywhere...the battery is encased and not meant to be removed/replaced.

Me (12/2/2019, 5:09:21 PM): 450 VA
Me (12/2/2019, 5:09:23 PM): 255 watts
Me (12/2/2019, 5:09:40 PM): do you know if it can go on a plane?
Ross (12/2/2019, 5:10:26 PM): No it is only designed for domestic use.
Ross (12/2/2019, 5:10:34 PM): Are you taking the unit somewhere else?

Me (12/2/2019, 5:11:22 PM): so it can't exceed 100 wH
Me (12/2/2019, 5:11:37 PM): so what are the wH and max voltage on the battery itself?
Me (12/2/2019, 5:11:44 PM): it's not anywhere on the package
Me (12/2/2019, 5:11:47 PM): i can't find it on the battery

Me (12/2/2019, 5:22:04 PM): idk why you guys don't just print it on the battery like every other manufaturer
Me (12/2/2019, 5:22:06 PM): :-/
Ross (12/2/2019, 5:29:44 PM): I apologize for the delayed response time. It appears that we do not have the info that you are looking for because this unit does not have a replaceable battery. I apologize for the inconvenience.
