What it does well.
Key features
UNO TFT expressions. The colour display uses animated robot-style expressions to communicate charging and remaining-battery status at a glance.
Foldable magnetic stand. An 8–10N listed magnetic hold and folding support allow hands-free portrait or landscape viewing with a compatible phone/case.
20W wired, 7.5W wireless. USB-C wired output reaches up to 20W; the Qi surface is listed at 7.5W. Keeping those numbers separate prevents an unrealistic wireless expectation.
Pocket-size backup. At about 105 × 75 × 16mm and 144g, the 5,000mAh pack is designed for short mobile top-ups rather than large multi-day energy reserves.
Wired, wireless and recharge power explained
UGREEN lists up to 20W USB-C PD 3.0 output to a compatible wired device, 7.5W Qi wireless output and up to 18W USB-C input to recharge the power bank. These are three different directions or transfer methods; the 18W input rating does not describe phone output, and 20W does not describe the wireless coil.
The model can support a wired device and a wireless phone together. The exact official SKU page does not publish a two-device allocation table, so do not add 20W + 7.5W or assume both maxima remain available. Expect shared/reduced power and use one method at a time when speed and lower heat matter.
Magnetic attachment helps position a compatible iPhone, but the phone still decides its wireless rate. Case thickness, coil alignment, battery state, software and temperature can cause lower power or a pause. The 8–10N figure is a controlled magnetic-force reference, not a guarantee against drops during movement.
USB-C to a device. Up to 20W wired output with a compatible phone, cable and negotiated PD profile.
Wireless to a phone. 7.5W Qi wireless charging under compatible alignment and temperature conditions.
USB-C into the bank. Up to 18W input from a compatible power source.
Wired + wireless. Two-device operation is supported, but the exact shared wattage is not published for PB571.
Capacity and realistic backup expectations
The confirmed official capacity is 5,000mAh. The checked SKU-specific material does not publish nominal cell voltage, watt-hours or a rated 5V output capacity, so those values are not calculated from an assumed chemistry. For travel and compliance checks, use the rating printed on the product itself.
UGREEN describes this as emergency backup and gives a model-specific iPhone demonstration, but a fixed fill count is not transferable across phones. Phone battery size, battery health, screen use, cable or wireless mode, temperature and conversion losses all change the result.
Wired USB-C normally uses stored energy more efficiently than wireless charging because it avoids a second coil-conversion stage. Choose wireless for snap-on convenience and wired mode when getting the most useful device energy from the small pack matters.
Use scenarios
Compact phone reserve. Carry a smaller backup for commutes, events and short outings where pocket size matters more than maximum capacity.
Hands-free calls. Open the stand and attach a compatible phone for portrait video calls while it receives wireless power.
Two-device convenience. Charge one compatible device by USB-C and a phone wirelessly when slower shared power is acceptable.
Setup and usability guidance
- Check the phone and case: iPhone 12 series and later provide the intended magnetic arrangement. Use a compatible magnetic case where required.
- Remove interference: take off wallets, cards, metal plates and thick or weakly aligned cases before attaching the phone.
- Seat the ring: let the magnets centre the phone, confirm the charging icon and keep a hand on both devices until the hold is secure.
- Recharge by USB-C: connect a compatible source using the included USB-C-to-USB-C cable. The bank accepts up to 18W; a wall adapter is not listed as included.
Compatible devices and systems
The intended magnetic fit, Qi power and USB-C charging must be checked separately. A Qi-capable device without a magnetic ring may need an appropriate case for secure portable attachment.
iPhone 12 and later. The primary magnetic device class, subject to model dimensions, case fit, operating-system controls and 7.5W Qi negotiation.
Magnetic-compatible cases. Cases with a correctly centred magnetic ring; thick, metal-backed, wallet or misaligned cases can weaken grip and interrupt charging.
Nonmagnetic Qi devices. They may charge when the coil is centred, but secure attachment is not assured without a correctly aligned magnetic accessory.
What this product does
- Stores 5,000mAh of portable backup capacity in the compact black UNO body.
- Supports two-device wired-plus-wireless use, magnetic alignment, a foldable stand and an emoji TFT status display.
What this product does not do
- It does not provide 20W wireless output; the wireless tier is 7.5W.
- It does not include a confirmed wall adapter and is not intended as a normal laptop power source.
What to do
- Match the cable to the job: use an undamaged cable that supports the connector, current and charging protocol required by the chosen port.
- Keep it ventilated: place the power bank on a firm, open surface while fast charging or recharging; warmth is easier to manage when heat can escape.
- Support both objects when moving: magnetic force helps alignment but does not turn the joined phone and power bank into one impact-proof unit.
What not to do
- Do not cover it: avoid charging beneath bedding, clothing or inside an unventilated compartment where heat can build up.
- Do not expose it to hazards: keep away from water, fire, heaters, hot vehicles, prolonged direct sunlight and freezing or otherwise extreme conditions.
- Do not place cards or metal at the coil: remove wallets, payment cards, keys, coins and magnetic mounting plates before wireless use.
Warnings and limitations
- Lithium-battery care: use only within the conditions stated on the product label and manual. Built-in protection is a backup, not permission to use damaged equipment or block ventilation.
- Heat changes charging: the power bank or connected device may reduce output when warm. Wireless charging normally creates more heat than an equivalent wired session because energy crosses an air gap.
- Label check for travel: the online sources confirm 5,000mAh but provide no Wh figure. Use the physical unit's printed energy marking and ask the airline if the required rating is unclear; do not rely on a calculated assumption.
Magnetic care, storage and travel checklist
Keep the phone-facing surface clean, fold the stand before placing it in a pocket, and protect the TFT window from keys or grit. The magnetic hold can be weakened by an incompatible case and cannot prevent detachment after a knock.
Current IATA guidance places power banks in cabin baggage and requires protection from damage and short circuit. Because the checked online sources provide no Wh rating for this model, read the physical label and verify the airline's current requirements. Neither 5,000mAh alone nor this description is transport approval.
- Follow current crew instructions about onboard storage, use and recharging.

Questions buyers ask.
Is the 20W rating wireless?
No. 20W is the USB-C wired-output ceiling. The documented Qi wireless output for PB571 is 7.5W.
Is this power bank Qi2-certified?
Qi2 certification is not documented for this exact model. It uses Qi wireless charging with MagSafe-compatible magnetic alignment.
Can it charge two devices together?
Yes, one by USB-C and one wirelessly. UGREEN does not publish the exact two-device power split, so expect reduced/shared power.
What does the TFT display show?
It uses animated UNO expressions to indicate charging and remaining-battery status. It should be treated as a status guide rather than a laboratory measurement.
Which phones attach directly?
The intended magnetic fit is iPhone 12 series and later. Other phones or nonmagnetic cases require a correctly aligned magnetic-compatible case or ring.
Can the stand work in landscape?
Yes. The folding support is intended for portrait or landscape use with a securely attached compatible phone.
What is the recharge input?
The USB-C port accepts up to 18W from compatible equipment. That input ceiling is separate from the 20W wired device output.
What are the Wh and rated-output figures?
The checked online SKU-specific sources publish 5,000mAh but not Wh or rated 5V output capacity. Use the physical label and do not infer a compliance value from an assumed voltage.
What cable is included?
A USB-C-to-USB-C cable is confirmed, but the exact India page does not publish its length or power rating. A wall adapter is not listed.
Why can wireless charging slow or stop?
Poor alignment, a thick or metal case, foreign objects, temperature, software or the phone's battery state can cause the system to reduce or pause power.
Can I take it on a flight?
Check the Wh marking on the physical unit and the current policy for every carrier. Keep power banks in cabin baggage and protect them from damage and short circuit; no travel approval is implied.
