UGREEN PB311 25742 10000mAh Power Bank, 22.5W, Display
The UGREEN 10000mAh Power Bank (PB311, 25742) is a slim, 217g everyday power bank with a 20W two-way USB-C port for iPhones and a 22.5W USB-A port for fast-charging Android phones. A digital display shows the exact battery percentage, and it gives about two full charges to most phones.
The USB-C port delivers up to 20W Power Delivery. UGREEN's test takes an iPhone 15 to about 60% in 30 minutes.
The USB-A port supports up to 22.5W on compatible SCP and QC phones, so Android phones fast-charge too.
10,000mAh is enough for about 2.2 charges of an iPhone 15, 2.1 of a Xiaomi 13 or 2.0 of a Galaxy S23, according to UGREEN.
Recharge through the two-way USB-C port at up to 20W. UGREEN uses about 3 hours as the reference with a 20W charger.
One slim power bank in the bag covers a long day of calls, maps and social media.

UGREEN 25742, model PB311, is a slim 10,000mAh wired power bank with a bidirectional 20W USB-C port, a USB-A output rated up to 22.5W and a numerical battery-percentage display. Its headline wattages apply when one compatible output is in use. With USB-C and USB-A active together, the published total changes to 5V/3A, or 15W shared. It has no wireless charging coil and is intended mainly for phones, tablets, earbuds and other USB devices within its output range.
Two-way USB-C. The USB-C port both recharges the PB311 and powers a compatible device at up to 20W.
22.5W USB-A ceiling. The USB-A port supports up to 22.5W when used alone with a mutually supported fast-charging protocol.
Clear percentage display. The numerical LED readout gives a more useful remaining-charge estimate than four unlabeled lights.
Low-current mode. A dedicated mode helps keep output active for compatible earbuds, watches and other accessories that draw little power.
USB-C input and output use the same port. Its listed profiles are 5V/3A, 9V/2.22A and 12V/1.67A, with a 20W maximum. USB-A output lists 5V/3A, 9V/2A, 10V/2.25A and 12V/1.5A, reaching 22.5W maximum on a compatible device.
Those figures are negotiated ceilings for single-port operation. When both output ports are connected, UGREEN specifies a combined 5V/3A, or 15W total. The 15W is shared between both devices; it is not 15W per port. Disconnect the second device when one phone needs the best available fast-charging rate.
A device controls how much power it accepts. The correct connector alone does not guarantee PD, QC or a particular proprietary 10V mode; the power bank, cable and receiving device must agree on a common profile.
USB-C alone. Up to 20W output; also accepts up to 20W input to recharge the PB311.
USB-A alone. Up to 22.5W output through a compatible charging protocol and cable.
USB-C + USB-A. 15W combined at 5V/3A, shared by the two connected devices.
Wireless output. None. SKU 25742 is a two-port wired power bank.
The internal battery is specified as 10,000mAh at 3.7V, equal to 37Wh. UGREEN also publishes a 6,250mAh typical rated output capacity at 5V/3A. The lower 5V figure is expected because the pack raises cell voltage to USB voltage and some energy is consumed by conversion, cable resistance and device charging.
A phone-fill count still cannot be guaranteed from 6,250mAh. The receiving device may charge at a higher voltage, remain in use, warm up, stop before 100% or lose energy in its own charge circuit. Battery age and cable quality also affect the result.
Official model material uses an approximately three-hour recharge as a controlled reference with compatible 20W equipment. Treat that only as a test-based guide: a lower-powered adapter, cable losses, temperature or charging another device can extend the time.
Phone top-ups. Use USB-C PD or the compatible USB-A protocol for everyday iPhone or Android charging away from a socket.
Two-device sharing. Power a phone and earbuds together, accepting the published 15W combined ceiling.
Slim daily carry. The roughly 16.5mm-thick body and percentage display suit work bags, commutes and planned backup power.
The PB311 is operating-system independent. Compatibility depends on the receiving device's USB charging input, its supported protocol and the cable used.
USB-C phones and tablets. Compatible iPhone, iPad, Galaxy, Pixel, Xiaomi, OnePlus and other devices that accept one of the published USB-C profiles.
USB-A cable users. Devices that charge through a USB-A-to-USB-C, USB-A-to-Lightning or another correctly wired cable and negotiate a supported profile.
Laptop limitation. At 20W USB-C maximum, it is not a normal primary supply for most USB-C laptops, even if a laptop accepts a slow emergency input.
Keep both ports free of lint and moisture, avoid bending plugs while connected, and protect the percentage display from hard impacts. The displayed percentage is an estimate and can settle after a high-load device is connected or removed.
For air travel, use the printed 37Wh energy rating when checking policy. Current IATA guidance places power banks in cabin baggage and requires short-circuit protection; carrier-specific limits and onboard-use rules still apply, so the capacity alone is not transport approval.
A wall charger and USB-C-to-USB-C cable are not part of the confirmed package. Use a separately sourced cable when the receiving device or chosen adapter requires a different connector.
USB-A is listed up to 22.5W, while USB-C is listed up to 20W. The receiving device and cable must support the relevant profile.
Total output changes to 5V/3A, or 15W shared between USB-C and USB-A. It is not 15W on each port.
The same USB-C port can accept up to 20W to recharge the PB311 and deliver up to 20W to a compatible device.
10,000mAh is measured at the 3.7V cells. The rated 6,250mAh figure is measured at 5V/3A after voltage conversion and normal energy loss.
No. SKU 25742 has one USB-C port and one USB-A port; it has no Qi or magnetic charging surface.
Its USB-C ceiling is 20W, which is below the normal requirement of most laptops. Some low-power devices may accept limited input, but this is not a primary laptop power bank.
It helps maintain output to compatible earbuds, watches, fitness bands and other accessories that draw too little power for ordinary automatic detection.
UGREEN uses roughly three hours as a controlled reference with compatible 20W equipment. Actual time varies with the adapter, cable, temperature and simultaneous use.
The confirmed package contains a 0.5m USB-A-to-USB-C cable. A USB-C wall adapter and USB-C-to-USB-C cable are not included.
It can power two devices, but both share a 15W combined ceiling. Disconnect one device when the other needs the best single-port rate.
Its labelled energy is 37Wh, but travel acceptance is controlled by the airline and route. Keep it in cabin baggage, protect it from damage and short circuit, and check current rules.
