@MarkDaSpark And the FAA/TSA limit for battery size in carry-on items applies to all batteries, as a business acquaintance discovered when researching how to keep a laptop powered in the field. 12V18Ah AGM is over the limit, but 12V16Ah is just under it.
Given that there were reportedly 50 cabin incidents of in-flight lithium battery overheating on commercial aircraft in August of this year, look for additional scrutiny to start getting applied to this subject. (Changes in the regs are unlikely to happen very fast unless something dire occurs.)
I know it says “Gallium Nitride (GaN) technology”, just be aware that TSA agents may not be aware that’s different from Lithium ones. And over a certain amount (15?) they’ll take them away at the checkpoint.
So make sure you bring documentation if traveling by air!
Double check the TSA website to verify that you can fly with them in carry-on baggage. They might just confiscate them in checked baggage.
Edit: If you’re traveling by car or just out and about, these are definitely handy for your devices. Just check on air!
@MarkDaSpark please don’t spread misinformation. The batteries are Li-ion. GaN refers to the charging circuitry. If you or someone reading this were to try to argue otherwise with TSA it could lead to embarrassment.
I hadn’t heard of joyfar before a couple months ago. Their products have been popping up on woot recently too. I bought a two pack of the 30,000 mAh and have had no trouble with them in my carry-on bags. I have flown a couple times with them recently. I think the TSA says that there is a 30,000 limit so there is that.
Edit… They work pretty well so far. I don’t have any actual testing equipment, but it seems they may be overstating the actual capacity by a little bit.
@El_Oel I’m reminded of an old movie (Battlefield Earth; not great, but bits if interesting trivia) where aliens have conquered Earth and are using humans to dig for gold. One human sneaks off into the ruins of Fort Knox when his tribe is going to be short their quota and brings back bars. The aliens raise an eyebrow that these starved sticks could mine, smelt, and shape gold for them. (But of course to push the “too greedy to be smart” tag, they accept the gold all the same.)
I’m guessing one reason these are here is the inclusion of the obsolete “ lightning” cable. Makes me guess these are vintage 2023-24 at best. What do we know about Mfr date? (And yes I understand some people still have older phones)
@pmarin The 30Ah unit I ordered during the 'thon shows no manufacture date, but arrived at a self-reported 74% charge. I suspect that the others will be similar; we shall see.
Bought the 2pack of Joyfar “30000 mAh/115.5Wh” batteries earlier. Complete crap and false advertising. With testing, the batteries were only capable of accepting 90Wh of power from the wall from 0-100% charge, and this is before conversion losses.
I would be surprised if you even got 2/3 of the advertised capacity with these things.
@MeLlamoScott@minuette TSA goes by the claimed capacity printed on the case, not the actual measured amount. And it might not even be a complete lie; they may be claiming the total energy extractable if the pack is discharged to zero, even though the battery management circuitry will presumably stop the output before it falls below the capacity-loss level.
Possibly more relevant, inflation of capacity numbers is a hallowed tradition in the PRC white-box electronics field. Amazon had listings for flashlights claiming outputs of 99,000,000 lumens when I last looked, which is likely a 200,000X rate of overstatement. Amazon does not seem to care. (The claims for the loudness of accessory car and truck horns are even more ludicrous; one stated an output of over 600db, an energy level that would have destroyed every solar planet and the Sun itself. TTC tested them a while back. The 600db horns failed to cause a planet-dismantling event.)
CCC compliant? If not and even if made in China you cannot fly or bring it in the country! I had to leave all my power banks at home because they didn’t have the CCC logo…. And yes they seem to inspect carefully…
@skaterdad Yes, the JOYFAR Portable Charger Power Bank meets CCC (China Compulsory Certification) compliance standards as indicated by its global safety certifications.

I’ve been holding off getting a new power bank, but I’m sick of micro-USB, so…
/giphy friendly-melodious-fezziwig
The quoted capacity puts this unit very close to the limit for air travel in carry-on. (Lithium batteries are fully prohibited in checked bags.)
@werehatrack
Except these are Gallium … not Lithium. But still a concern. See my post 30 seconds after yours.
@MarkDaSpark The IC chip controlling the lithium battery pack’s output to the USB-C port is made using gallium nitride. The batteries are not.

@MarkDaSpark Gallium nitride is used in the circuitry. The batteries are still lithium.

Replacing the one I love in the same form factor that is USB only and beat to heck.
/giphy twinkling-terrific-longjohns
@DLPanther ITYM “USB-A only”. The fact that your old one from the same brand has lasted long enough to get beat to hell is encouraging.
Proof once again that the largest lithium deposits in the world are located in Texas.
@El_Oel I’m reminded of an old movie (Battlefield Earth; not great, but bits if interesting trivia) where aliens have conquered Earth and are using humans to dig for gold.

@El_Oel Battlefield Earth is hilarious for Travolta’s insane laugh. Make a drinking game of it!

@minuette Well, at least that brings it technically to the point where you can fly with it (100 Wh or less).

@MeLlamoScott @werehatrack
Good Lord! Who tested it? They took quite a risk!
Wait, no air compressor? Do these even have a flash light?
I thought for sure that Santa’s little helper was going to be a Simpsons reference.
Anyways- I bought one.

Got that from amazon
I love the Toms Hanks at different hairlines.
@NombreDeUsuario The one on the left looks more like Matt Damon, who would probably need two of Tom Hanks to rescue him.

Anyone know how much these weigh?
/buy --color purple
@walarney It worked! Your order number is: spectacular-toasted-feast
/showme spectacular toasted feast
took me 4 tries to remember the syntax…
These are just under the TSA limit of 100 wH. You can carry on 2, btw.
Formula to convert wH to mAh:
mAh = (Wh × 1000) / V
100wH = 27,027.03 mAh.
These are 25,000 mAh, and just under the limit.
