UGREEN 300W Power Bank, 48000mAh/153.6Wh (25286)
UGREEN 300W Power Bank, 48000mAh/153.6Wh (25286) is a rechargeable 48,000mAh (153.6Wh) USB power bank with three USB-C ports and two USB-A ports. It is intended to charge compatible USB devices away from a wall socket while clearly showing remaining battery information on its display.
Overview
The five-output system is listed up to 300W total: USB-C1 supports up to 140W input/output, USB-C2 and USB-C3 up to 100W each, and USB-A1/USB-A2 up to 22.5W each. Port-nameplate figures are conditional single-port or total maximums; actual power is negotiated and can be redistributed when more than one device is connected.
Capacity in mAh describes the internal battery at its nominal cell voltage. Usable 5V or higher-voltage output is lower after conversion losses, cable loss, temperature and the power bank’s reserved safety margin.

Key features
The defining functions of this exact SKU are separated from headline marketing so connector roles, power, data, length and battery limits remain clear.
- 48,000mAh nominal capacity with a verified 153.6Wh energy rating.
- The five-output system is listed up to 300W total: USB-C1 supports up to 140W input/output, USB-C2 and USB-C3 up to 100W each, and USB-A1/USB-A2 up to 22.5W each.
- USB-C1 is bidirectional PD 3.1: up to 140W output or 140W recharge input, including 28V/5A and PPS 3.3–21V/5A.
- USB-C2 and USB-C3 each support up to 100W output and PPS up to 3.3–21V/5A with compatible equipment.
- USB-A1 and USB-A2 each support up to 22.5W with supported USB-A charging protocols.
- Smart LED display plus three-mode area light for checking remaining battery state instead of relying only on indicator dots.
- Automotive-grade LiFePO4 cell chemistry; official exact-model claim of more than 80% capacity after 3,000 cycles under its test conditions.
- Integrated carry handle, non-slip base, smart status display and an LED area light with bright, low and SOS-style modes.
- Heavy 1637g tabletop/ground-use format rather than a pocket power bank.
- Built-in protection design is intended to monitor over-voltage, over-current, over-charge, over-discharge, short-circuit and temperature conditions; correct use and undamaged equipment remain essential.
Performance and planning
Headline watts and gigabits are negotiated maximums, not universal results. Plan around every device, port, cable, charger, battery state and protocol in the path.
The 300W figure is a maximum system total under a supported port allocation. It does not mean every port simultaneously delivers its own nameplate maximum. The exact gallery also illustrates a particular multi-device combination at 200W; that is one allocation example, not a contradiction of the 300W system ceiling.
USB-C1 can recharge at up to 140W using a compatible PD 3.1/EPR charger and appropriately rated USB-C cable. The included official 240W USB-C cable supports the cable path, but a wall charger is not included.
When multiple outputs are active, the controller can reallocate the available total. A device may briefly reconnect or renegotiate when another cable is inserted; connect the most power-hungry device to the highest-rated port first.
Advertised phone or laptop recharge counts are controlled examples, not guarantees. Device battery size, starting level, screen use, radio activity, temperature, protocol and conversion efficiency all change the result.
Charging normally tapers as the receiving battery fills. A lower displayed rate near full charge does not by itself indicate a fault.
Use scenarios
These practical examples keep the exact connector direction, supported protocol and safety limits in view.
Mobile workstation
Reserve USB-C1 for a 140W-class laptop and distribute smaller loads across the remaining ports within the 300W total.
Home outage essentials
Keep USB-powered communications and low-voltage devices running temporarily. This unit has no AC outlet and is not a household UPS.
Area light
Use the integrated light for short-duration task or emergency illumination while monitoring remaining battery on the display.
Ground transport only
At 153.6Wh, current IATA power-bank guidance forbids this power bank in passenger baggage. Plan road or rail transport only where local rules allow, or use a regulated dangerous-goods cargo service.
Setup and usability guidance
Use this sequence for a controlled first connection. Follow the connected-device maker’s stricter instruction whenever it differs.
- Charge the power bank on a hard, dry, ventilated surface using the designated USB-C input and a standards-compliant charger/cable that supports the required input profile.
- Before first use, verify the display operates normally and inspect the enclosure and all 5 ports for damage, contamination or looseness.
- Choose the output port by the connected device’s power need. Use the highest-rated USB-C path and an appropriately rated cable for a laptop or other high-power device.
- Connect one device first and confirm stable charging. Add further devices one at a time, expecting the available total to be shared.
- Keep the power bank uncovered and away from direct sun, bedding and other heat sources during charge or discharge.
- Disconnect finished devices, then recharge the power bank before long storage. Do not leave a depleted lithium battery unused for extended periods.
Compatible devices and systems
A connector that fits is only the first check. The host, accessory, operating system and power source must support the requested function.
- USB-C laptops and mobile workstations that accept standard PD 3.1/PD 3.0 profiles up to the selected port maximum.
- USB-C handheld gaming systems, tablets, phones, cameras and accessories within the supported voltage/current profile.
- USB-A phones and accessories using supported SCP, QC, AFC, Apple 5V/2.4A or BC1.2-class modes.
- Not compatible with AC appliances, barrel-input laptops without a supported USB-C PD input, or equipment requiring more than the system’s available USB output.
- USB-C phones and tablets that accept standard USB Power Delivery or one of the specifically supported negotiated profiles.
- USB-A phones, accessories and legacy cables within the listed USB-A port output.
- Low-power wearables or earbuds only when the connected product and power-bank mode support stable low-current charging.
- The operating system is not the deciding factor for ordinary charging; port protocol, voltage/current profile, cable rating and device input are decisive.
- Not every proprietary phone fast-charge mode is universal. Unmatched devices fall back to a mutually supported standard profile.

Warnings and limitations
Review these electrical, thermal, transport and physical limits before connecting valuable equipment.
- The battery is 153.6Wh. Current IATA power-bank guidance effective in 2026 forbids power banks above 100Wh and up to 160Wh in passenger baggage; it is not a matter of airline approval for this product category. Do not take SKU 25286 in cabin or checked passenger baggage.
- Do not bring this 153.6Wh power bank onto a passenger aircraft. For necessary shipment, consult the carrier about regulated lithium-battery dangerous-goods cargo procedures rather than ordinary baggage.
- Stop using the product if a connector, cable jacket, battery enclosure or plug is bent, cracked, loose, swollen, scorched or unusually hot.
- Keep connectors dry and free of lint or metal debris. Disconnect power before cleaning; never probe a port with metal.
- Never modify, splice, crush or tightly knot a charging cable, charger or battery pack.
- Lithium batteries require careful end-of-life handling. Use an authorised battery/e-waste channel; never place the product in fire or ordinary mixed waste.
- This is a 153.6Wh battery weighing 1637g. Carry it by the handle with a supporting grip, prevent falls and never suspend other loads from the handle.
- Keep the unit upright on a stable, dry surface with ventilation around every side. Do not operate in rain, standing water, a hot parked vehicle or direct sun.
- The area light is not a road flare, certified safety beacon or substitute for required emergency equipment.
- High-power 28V/5A charging needs a genuine PD 3.1/EPR chain. Do not use under-rated cables or loose adapters.

Product-specific FAQ
Open any question for a concise exact-model answer. The native collapsible format keeps this long guide easy to scan on a phone.
What is the exact battery capacity of SKU 25286?
48,000mAh nominal, corresponding to 153.6Wh. Usable delivered energy is lower after conversion and safety reserves.
What is the maximum output?
300W maximum system total; USB-C1 up to 140W. It is conditional on the correct port, compatible device, cable and current power-sharing state.
Can it charge a laptop?
Yes, for USB-C laptops that accept standard PD profiles. USB-C1 supports up to 140W and USB-C2/C3 up to 100W, but the system total and connected-device negotiation still apply.
Can it charge more than one device?
Yes, using its three USB-C ports and two USB-A ports; the total is shared and per-port speed can reduce when several outputs are active.
Can I take it on a flight?
No under current IATA power-bank guidance. At 153.6Wh, it is above the 100Wh passenger power-bank limit and forbidden in both cabin and checked baggage. Use permitted ground transport or regulated cargo procedures.
Can it go in checked luggage?
No. Power banks are spare lithium batteries and must not be placed in checked baggage.
Is the advertised mAh fully available at USB output?
No. The nominal mAh is measured at internal cell voltage; conversion to 5V or higher, cable loss, temperature and safety reserve reduce usable output.
Does it support wireless charging?
No. This exact product charges through its USB outputs.
Can I use it as a UPS while recharging it?
Do not rely on it as a UPS. Continuous pass-through operation is not verified here and can add heat and battery cycling.
Is a wall charger included?
No wall charger is identified in the official package list. Maximum 140W recharge requires a compatible PD 3.1/EPR wall charger; a 240W USB-C cable is listed as included.
Why is the output below the headline wattage?
The connected device requests its supported profile, charging tapers near full, heat can reduce power and simultaneous outputs share the total.
What if the battery swells, leaks or becomes very hot?
Disconnect it if safe, move it away from combustible materials without puncturing it, stop use and contact an authorised battery service. Do not ship or discard it casually.

This is probably my favorite new UGreen product in a long while. The capacity is enormous but is packaged in a compact, attractive form factor. The light is a useful feature when camping and I love that it supports fast charging. I have an Anker 548 battery bank that used to be my go-to camping battery with 60,000 mAh but it’s twice the size and has a maximum output per port of 30 watts. While this battery doesn’t boast the same capacity, it’s less than half the size in footprint but still offers 80% of the capacity and boasts quicker charging speeds and a more attractive screen. The only feature this lacks over the Anker is a solar charging port, which I honestly never used on the Anker due to impracticality. My only gripe with this UGreen battery is that the input port is on the front of the device. I would have personally preferred it to be on the back, but that’s a nitpick.

“After 7 days with the UGREEN 300W 48,000mAh Power Bank, I’m impressed with the build quality, the multiple ports (3 USB-C + 2 USB-A), and the fact that it managed to fast-charge both my laptop and phone with ease. The smart display is very useful and the LED lantern mode is a thoughtful addition.
On the flip side: the unit is physically heavy and takes up space, so I don’t carry it every day. Also, while the rated 48,000 mAh sounds great, the real-world gains over smaller units are less dramatic for my usage (mostly phone/tablet). If I only focused on phone-charging, a lighter model might suffice. That said, for trips/outdoor/back-up use this gives excellent peace of mind.
I’d give it 5 stars because of how well it performs and how many features it crams in; my only suggestion might be to include clearer info about port-sharing limits and maybe include an additional cable or charger in the box.”

Awesome backup
T
In over a decade of experiences with countless brands, along with no-name brands, this truly redefines the way I measure capacity, features, mobility , ruggedness, etc. This will qualify as one of the most reliable, power Bank/inverters, backups, of it's kind.Charge time is exemplary.It is heavy but the handle is secured.The sos dim/bright light came in handy.Not covered in markets info clearly in features;This is a HUB. While charging the PowerBank, simultaneously, device(s) can still be charged.Side by side with Ankers C100W PowerBank, this goes above & beyond.
S
It's a powerhouse for all my accessories...! Great to have it the quality of the product is awesome and it works as described.
P
Runs fine and best part is it charges under 2 hours if used with 140w charger
R
Bisher super. Schnelles Laden. Gute Kapazität. Gibt's zwar billiger aber dann nur mit langsameren Ein und Ausgängen... Habe nichts zu meckern
S
Design wise plastic and it's good but capacity doesn't feel like 48000mah as it's draining 1 percent to charge 4 percent of my 5500mah phone.

Looks good however to early to comment, will update in few months.

Ich hatte es für eine Woche zum Wandern und Outdoor sachen machen mit und hielt einfach bis zum Schluss durch, gewohnte Ugreen Qualität halt... Einfach zu empfehlen für Leute die viel draußen Unterwegs sind
M
Mein Akku lässt sich nicht laden. Scheint defekt. Rückgabe wird aber von Amazon nicht akzeptiert. Das kann doch irgendwie nicht sein.

Hi to All,I bought this power bank because I needed something that lasted awhile before I had to charge it again. It did just that. I use this lil buddy to keep my Samsung phone, along with two other cell phones topped off for an entire week. As a bonus, I can also keep my 10k power bank charged from 50% twice. After a week I'm looking at around 20% battery left. Keep in mind, because of heat dissipation during charging/recharging, the battery mah may vary. So don't get all caught up in labels. Cool light on the side is a bonus. Great carry handle. Recharges fast, but I don't use that feature, since it's awhile before I need it again. Great buy. Get yourself 1 if you need power for your many devices, or if you have homies you chill with often.

Got the thing in this morning. Brand new. Very excited to put the new battery through its paces.The battery bank will not allow me to use all three usb c ports to charge three devices at the same time.Got a portable mini pc, my laptop, and a pair of bluetooth headphones. No matter what I do, when I plug in a third USB C port, the first one loses power immediately and stops charging. The only way I can get this to work as intended is to not use that first USB C port on the front of the bank.... but that's the only one that can go to 140w... going to be returning. Very disappointed. Been using Ugreen products for a long time now. I own one of their battery banks, two usb c switches, tons of their cables, three of their charger bricks, and numerous stands and other items. Last year, their 300w Desktop charger started losing ports (port 1 and port 3 no longer work) and now this... Really wish I didn't have to use Anker for everything.
