UGREEN PB503 5000mAh 22.5W Mini Power Bank with Built-In USB-C – 35338
The UGREEN 5000mAh Mini Power Bank (PB503, 35338) plugs straight into your USB-C phone, so there is no cable to carry. At 112g it slips into any pocket, charges at up to 22.5W, shows the exact battery percentage and has a fold-out stand for videos while it charges: an easy emergency top-up for iPhone 15 and later and USB-C Android phones.
UGREEN's test shows an iPhone 16 reaching about 55% in 30 minutes. Compatible SCP phones charge at up to 22.5W, and USB PD phones at up to 20W.
Flip out the stand to prop your phone up for video calls, films or recipes while it charges, in portrait or landscape.
Pass-through charging lets you plug the power bank into a charger and still top up your phone from it at the same time.
At 79 × 38 × 26mm and about 112g, it fits a jeans pocket, a small sling bag or even a purse.
Phone low on the way home, in a queue or at a concert: plug in and keep going.

Yes. USB-C iPhones (iPhone 15 and later) plug directly into the built-in USB-C connector, subject to case fit.
Not directly, because those iPhones use Lightning. Charge them from the USB-C port with a USB-C to Lightning cable, sold separately.
UGREEN quotes about 1.14 charges for an iPhone 16, 0.98 for a Galaxy S24 and 0.86 for an iPhone 16 Pro Max. It is best used as an emergency top-up.
No. 22.5W needs a phone with SCP support. USB PD phones such as iPhones charge at up to 20W, and others at the rate they negotiate.

Plug the built-in USB-C connector directly into a compatible phone for convenient cable-free charging. Get up to 22.5W output, a digital battery display, dual-device charging and a foldable phone stand in a compact 112g design.
Cable-Free USB-C. Connect directly to a compatible USB-C phone without carrying a separate charging cable.
Up to 22.5W. Supports up to 22.5W through compatible SCP charging profiles and up to 20W USB Power Delivery.
Two-Device Charging. Use the integrated connector and USB-C port together, with up to 15W total shared output.
Digital Battery Display. Check the remaining battery percentage at a glance instead of relying on basic indicator dots.
Foldable Phone Stand. Supports portrait or landscape viewing while you watch videos, make calls or follow directions.
Pocket-Friendly. Measures approximately 79 × 38 × 26mm and weighs only about 112g.
No extra cable required
The integrated USB-C connector plugs directly into a compatible phone, tablet, earbuds case or other small USB-C device. It is especially convenient for commuting, events, travel and emergency top-ups when you do not want a charging cable hanging from the phone.
A protective connector cap helps cover the USB-C plug when the power bank is stored in a pocket or bag.
Protect the phone’s USB-C port. Support both the phone and power bank while they are connected. Do not bend, twist or use the attached power bank as a handle. Avoid placing the connected combination inside a pocket or bag where sideways pressure could be applied to the phone’s charging port.
With a 5000mAh internal battery rated at 3.6V/18Wh, this compact charger is designed primarily for portable emergency charging and extending your phone’s usable time away from a wall socket.
Its rated output capacity is 2500mAh at 5V/2.4A. The difference between internal cell capacity and rated output is normal because energy is consumed during voltage conversion and charging. The actual percentage added to a phone depends on the phone’s battery size, charging efficiency, temperature, background activity and whether the phone is used while charging.
Open the integrated stand to support a compatible phone while it charges. Portrait mode is useful for video calls, messages and short-form content, while landscape mode is convenient for watching videos or following travel information.
Place the phone on a stable, level surface. The stand is intended for stationary viewing and should not be treated as a protective phone grip.
Know before you go
The integrated LED screen displays the power bank’s remaining battery percentage, making it easier to decide when it needs recharging.
In addition to the built-in USB-C connector, the PB503 includes a separate USB-C port. Both can provide power, allowing two compatible devices to be charged at the same time.
When both outputs are used, the maximum combined output is 5V/3A or 15W shared. For the quickest available charging, connect only one device.
Pass-through charging is supported, allowing the power bank to receive power while supplying power to a connected device. Charging may be slower and additional heat can be produced, so separate charging is preferable when time allows.
USB-C iPhone. Compatible with USB-C iPhone models, including the iPhone 15 series and later USB-C generations.
Android smartphones. Compatible with many USB-C Samsung Galaxy, Google Pixel, OnePlus, Xiaomi, Huawei, Motorola, Nothing and other smartphones.
Tablets and accessories. Suitable for compatible USB-C iPad models, Android tablets, earbuds cases, handheld accessories and other low-power USB-C devices.
Compatibility limitations.
The built-in connector may work with cases up to approximately 2.5mm thick. Compatibility also depends on the case’s bottom edge and the size and position of its USB-C opening.
If the connector cannot be inserted fully without force, remove the case before charging. Never force the connector because this may damage the phone’s port or the power bank.
Recharge the PB503 using a compatible USB-C PD charger and the supplied USB-C cable. A complete recharge takes approximately 2.5 hours under suitable test conditions with a compatible 20W charger.
Before first use, fully charge the power bank without interruption. Recharge time can vary according to the charger, cable, ambient temperature and whether another device is being charged simultaneously.
Integrated safeguards help protect against conditions such as overcharging, over-discharging, excessive current, overvoltage, overload, overheating and short circuits.
The battery is rated at 18Wh, below the commonly applied 100Wh cabin-baggage threshold. Power banks are generally required to travel in cabin baggage rather than checked baggage. Airline and airport rules can differ, so always confirm the latest requirements before travel.
The PB503 supports several commonly used fast-charging protocols, including USB PD, Quick Charge, SCP and FCP. Charging speed is automatically negotiated with the connected device and can vary by model, battery level, temperature and supported protocol.
Please note: AC wall charger and phone are not included.
Yes, USB-C iPhones such as the iPhone 15 series and later USB-C models can connect to the built-in USB-C plug, subject to case fit.
No. Those models use a Lightning port. They can be charged from the separate USB-C port using a suitable USB-C-to-Lightning cable, sold separately.
No. Up to 22.5W requires a compatible SCP charging profile. USB PD output is up to 20W, and other devices may charge at a lower negotiated rate.
It depends on the phone. This is a compact emergency top-up power bank with a rated output capacity of 2500mAh at 5V/2.4A. Many modern phones have batteries larger than this rated output.
5000mAh is measured at the internal cell voltage of 3.6V. Some energy is consumed when converting that voltage to USB output, so the rated deliverable capacity at 5V is lower. This is normal for power banks.
Yes. Use the built-in connector and USB-C port together. Maximum combined output is 15W shared, so charging will be slower than single-device charging.
Yes. It can receive power while charging a connected device, although speed may be reduced and extra heat may be generated.
Approximately 2.5 hours with a compatible 20W USB-C PD charger under suitable conditions. Actual time can vary.
It may work with cases up to approximately 2.5mm thick. A thick bottom edge or narrow connector opening can still block the plug, in which case the case should be removed.
Yes. The foldable stand is designed to support both orientations on a stable surface.
No. It charges through its built-in USB-C connector or the separate USB-C port.
It is not recommended as a laptop power bank. Its 22.5W maximum output and 5000mAh capacity are intended primarily for phones and smaller USB-C devices.
No. A 0.5m USB-C-to-USB-C cable is included, but the wall charger is sold separately.
Its 18Wh rating is below the commonly applied 100Wh cabin-baggage threshold. Power banks usually need to remain in cabin baggage. Confirm the airline’s latest policy before travelling.
The product is covered by a 1-year UGREEN India warranty, subject to the applicable warranty terms and proof of purchase.
