Designed for adventurers, travelers, and those seeking reliable backup power at home, this powerhouse battery pack promises to revolutionize the way we stay charged in an increasingly mobile world.

With a maximum total output of 300 W and PD3.1 140 W bidirectional charging, the UGREEN portable charger ensures a swift and efficient power solution. Equipped with 5 ports, it allows multiple devices to charge simultaneously, reducing wait times and maximizing productivity. Thanks to its 140 W self-charging speed, achieving a full charge takes a mere 1.5 hours, making it ideal for busy schedules and time-sensitive situations.





Featuring an impressive 48,000mAh capacity, this portable charger offers up to 10 days of power on a single charge. Whether embarking on a long journey, enduring back-to-back meetings, or enjoying outdoor adventures, the UGREEN power bank ensures users stay connected without interruption. With 10.8 charges for an iPhone 15 Pro and 1.1 charges for a MacBook Air M2 15, the device can be relied on to keep essential electronics powered up whenever and wherever.

Safety and longevity are paramount with the UGREEN battery pack. Utilizing automotive-grade, high energy-density Lifepo4 batteries, it boasts superior energy storage capabilities, enhanced safety features, and an extended lifespan. Even after 3,000 battery cycles, the capacity remains above 80%, surpassing traditional batteries by 600%.

For added versatility, the UGREEN portable power bank features LED lighting with three modes: high light, low light, and SOS mode. Whether navigating through darkness or signalling for help in emergencies, this device ensures reliable illumination anywhere.

Included with the UGREEN 300 W 48000mAh power station are essential accessories such as a 240 W USB-C to USB-C cable, user manual, and warranty card, backed by UGREEN's dedicated customer service. (Note: Wall charger not included)

The UGREEN 300 W 48000mAh Portable Charger Power Bank is available for $199.99 on Amazon.

Wall charger not included

A product that has only two functions (get charged and give charge) is missing a critical component to perform the main function it needs to operate.

 

[LabRat 891]

Seems a bit low capacity for any of the 'lifestyle' applications that come to my mind.
-Gaming/Workstation Laptop
-'Pedestrian' Laptop + eGPU Enclosure +external display(?)

I get that LiFePo4 batteries are bulkier than LiPo pouches but, this just seems a bit lacking for the $200 price point.
Maybe I'm missing something?

Unless one already has a heafty USB-PD charger for one's laptop, that's quite an additional expenditure.

Specially if you want to hit that 1.5h charge time they're boasting about.

"Featuring an impressive 48,000mAh capacity..."

At what voltage? I much prefer Watt Hours


10 batteries in parallel have ten times the Ah as the same ten batteries in series, while the latter is actually preferable.

Apple's MacBook Air M2 15" claims a

• 66.5-watt‑hour lithium‑polymer battery

So, that's 73.15Wh claimed capacity from UGREEN.

Probably 75+Wh in-built (assuming conversion and transmission losses).


So... Does that mean this could be taken on a commercial aircraft? (<100Wh)

 

[unwind-protect]

Yeah, what is the capacity in Watt-hours? This is important for e.g. flying with the thing, TSA limit is 100 Wh.

Ugreen really like to give Ah since the number is bigger. Silly.

 

[LabRat 891]

Time is 1:06 a MacBook Air which is not very power hungry. Expect a lot less uptime for other laptops.
Unless it's a very short flight and you're very, very busy I don't think it's worth taking it with you on a flight.

Kinda moot point, from that PoV.
IIRC from trying to find the MBA M2 15"'s batt capacity, the battery life on one charge is more than enough for most-all flights. 12-14 hours.

'Was thinking more for those w/ multiple devices. Like, a portable workstation, etc. trying to get some work/play done on their flight. The <100Wh 'limit' was relevant, as TSA has a hard cut-off on batt. capacity that can be brought aboard a commercial airliner.

Capacity in mAh is at nominal voltage, so most likely at 3.7-3.85V, so capacity in Wh is 177 to 185 Wh. Limit for airplane is around 27000 mAh.

My mistake. I was looking a the wrong unit.

I suppose to be ~3.7 volts and 177Wh.
Example of voltage got from Sandberg - Survivor declared 72000mAh and have 266 Wh.

 

[LabRat 891]

Capacity in mAh is at nominal voltage, so most likely at 3.7-3.85V, so capacity in Wh is 177 to 185 Wh. Limit for airplane is around 27000 mAh.

LiFePo4 (as this unit advertises) is lower nominal cell voltage than most other common Lithium chemistries in consumer products.
3.2V is Nominal, 3.5-3.6V typ. 'peak charge state'.

Thing is... using 3.2V x 48Ah, doesn't line up whatsoever with the advertised usable device-charging capacity.
UGREEN is definitely playing with the numbers. ie, "Marketing Wank"

You/we have to buy a quality ugreen charger it seems.

My bad, didnt see it is lifepo4. In that case it is just 153Wh. It looks like you can get 130Wh when charging phones but only 70Wh when charging laptop. Seems like very inefficient step up convertor.

have to complete the set

I bet some rich dude is lugging all this shit around too

Rich? I always assumed products like these were for people in deep consumer credit card debt

 

[unwind-protect]

... and why is this thing not "AI"?

Capacity in mAh is at nominal voltage, so most likely at 3.7-3.85V, so capacity in Wh is 177 to 185 Wh. Limit for airplane is around 27000 mAh.

TSA limit is 100 Wh.

seems fair to me

to big to be an easy daily carry, to small for camping
