UGREEN 15086 10000mAh Magnetic Power Bank, 20W USB-C, Stand
Overview
UGREEN 15086 is a 10,000mAh magnetic wireless power bank with one bidirectional USB-C port, one USB-A output, a Qi charging surface and a foldable phone stand. Its 20W USB-C and 22.5W USB-A figures are wired single-port ceilings; wireless output is a separate 5W, 7.5W or 15W tier chosen by the receiving device. It can serve up to three devices at once, but UGREEN does not publish the exact three-way power split, so multi-device use should be planned for convenience rather than maximum speed.
- 10000mAh / 37Wh
- USB-C up to 20W
- USB-A up to 22.5W
- Qi wireless up to 15W
What it does well.
Key features
Three charging paths. Use USB-C, USB-A and the wireless surface for a phone, earbuds or another compatible USB device. All advertised maxima do not apply simultaneously.
Magnetic alignment. The magnetic ring helps align compatible iPhone 12-and-later models or suitable magnetic cases. This is Qi charging in a MagSafe-compatible form factor, not a documented Qi2 product.
Foldable support. The rear stand supports portrait or landscape viewing while the phone is magnetically attached; keep the base stable and avoid forcing the hinge.
Battery indication. LED indicators provide an approximate view of remaining power so the pack can be recharged before a long day.
Wired and wireless power explained
The USB-C port accepts up to 20W to recharge the power bank and can deliver up to 20W to a compatible device: 5V/3A, 9V/2.22A or 12V/1.67A. The USB-A port is output only and reaches up to 22.5W through its listed 4.5V/5A, 5V/4.5A, 5V/3A, 9V/2A or 12V/1.5A profiles. A phone selects only a mutually supported profile; attaching a higher-rated cable does not force the maximum.
The Qi surface is listed for 5W charging with compatible AirPods cases, 7.5W with compatible iPhones and up to 15W with selected compatible Qi phones from brands such as Samsung, Google or LG. These are wireless ceilings, not USB-C output figures. Alignment, case material, temperature and the phone's own charging rules can lower the result.
UGREEN markets simultaneous charging of three devices. The exact product page does not provide a USB-C + USB-A + wireless allocation table. When more than one output is active, expect shared power and a lower rate than the individual-port headlines; do not add 20W + 22.5W + 15W and treat the sum as available output.
USB-C alone. Up to 20W wired output to a compatible USB-C device; the same port is the power-bank input at up to 20W.
USB-A alone. Up to 22.5W wired output with a compatible device, protocol and cable.
Wireless alone. 5W, 7.5W or up to 15W depending on the receiving Qi device and operating conditions.
Several devices. Up to three charging paths can operate, but the exact shared allocation is not published for SKU 15086.
Capacity and real-world expectations
The internal cell rating is 10,000mAh at 3.7V, equal to 37Wh. mAh at the cell voltage cannot be compared directly with a phone battery or USB output without accounting for voltage conversion. UGREEN does not publish a rated 5V output-capacity figure for this exact SKU in the checked official material, so no lower delivered-mAh number is invented here.
Actual usable energy depends on whether power is delivered by wire or wirelessly, the selected voltage, conversion losses, cable resistance, device temperature and whether the phone is being used. Wireless charging normally delivers less usable energy from the same stored 37Wh because the coil link creates additional conversion loss and heat.
A recharge-count claim would therefore be device- and condition-specific. Use 37Wh as the comparable energy label, then allow for conversion loss rather than expecting the full 10,000mAh to arrive at a phone battery.
Use scenarios
Commute backup. Attach a compatible iPhone magnetically for short top-ups without a loose phone cable.
Desk or hotel stand. Open the stand for portrait calls, landscape video or a visible bedside clock while charging.
Cable-first efficiency. Choose USB-C or USB-A when speed, lower heat and better use of stored energy matter more than magnetic convenience.
Setup and usability guidance
- Check the receiving device: confirm Qi support for wireless charging or choose the correct USB cable for wired use.
- Prepare the phone: remove metal plates, wallet attachments, cards and very thick cases. Use a magnetic-compatible case when the phone or case does not provide a suitable ring.
- Align the coil: centre the phone until the magnetic ring seats it, then verify the phone's charging symbol before moving it. Re-seat if charging cycles on and off.
- Recharge the pack: connect a compatible USB-C power source to the USB-C port. A wall adapter is not listed in the package; a lower-powered adapter can take longer.
Compatible devices and systems
Compatibility is determined separately for magnetic attachment, Qi power and wired charging. A phone can support Qi yet need a compatible magnetic case to stay attached.
Magnetic iPhones. iPhone 12 series and later models with their built-in magnetic ring, subject to model fit, current software and Apple's charging controls.
Qi phones. Other Qi-enabled phones can receive wireless power when their coil aligns, but may need a magnetic case or ring for secure attachment. Wireless tier varies by model.
Wired USB devices. Phones, tablets, earbuds and small USB devices that accept one of the published USB-C or USB-A voltage profiles with a suitable cable.
What this product does
- Stores 37Wh of rechargeable energy for portable top-ups.
- Supports a phone in portrait or landscape with the foldable stand and can power as many as three connected devices.
What this product does not do
- It does not document Qi2 support or Apple MagSafe certification; “MagSafe compatible” describes magnetic fit and Qi use.
- It does not include a wall adapter, and it is not a substitute for the higher continuous wattage required by most USB-C laptops.
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.
- Store thoughtfully: for extended storage, keep the unit in a cool, dry place away from direct sun and periodically check its condition and remaining charge.
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 treat a maximum as a constant: advertised wattage is a negotiated ceiling, not a promise that every device, cable or multi-port combination will draw it.
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.
- Magnetic and wireless caution: remove payment cards, keys, coins and metal plates from between the phone and power bank. Confirm alignment after changing a case or orientation.
Care, storage and travel checklist
Keep the magnetic face and phone back clean so grit is not trapped between them. Fold the stand before packing, protect the USB ports from loose metal, and avoid storing the unit under pressure from heavy items.
For flights, the printed 37Wh rating is the relevant battery-energy figure. Current IATA guidance says power banks should be carried in cabin baggage and individually protected from short circuit, while carriers may set tighter limits or prohibit onboard use. Verify the itinerary's current policy; this product description does not grant transport permission.
- For long storage, keep it cool and dry, away from conductive objects, and inspect it before returning it to service.

Questions buyers ask.
Is 20W the wireless charging speed?
No. 20W is the USB-C wired ceiling. Wireless charging is listed at 5W, 7.5W or up to 15W according to the compatible receiving device.
Is SKU 15086 a Qi2 power bank?
Qi2 is not documented for this exact product. It uses Qi wireless charging with a magnetic, MagSafe-compatible alignment design.
Can it charge three devices at once?
UGREEN markets up to three simultaneous charging paths: USB-C, USB-A and wireless. The exact three-way wattage split is not published, so expect slower shared charging.
What do 10,000mAh and 37Wh mean?
10,000mAh is the nominal cell capacity at 3.7V; 37Wh is the corresponding energy rating. Delivered phone energy is lower after voltage conversion and other losses.
What is the rated output capacity?
UGREEN does not publish a rated 5V output-capacity figure for this exact SKU in the checked official material, so one should not be inferred from the nominal mAh alone.
Which cases work for magnetic charging?
Use the bare back of a compatible magnetic iPhone or a properly aligned magnetic-compatible case. Thick cases, metal plates, wallets and weak or misplaced rings can prevent stable attachment or charging.
Can the stand be used in landscape?
Yes. The foldable support is intended for portrait or landscape viewing while the phone is securely attached. Keep the base stable and do not force the hinge.
How is the power bank recharged?
Use the USB-C port with a compatible USB-C power source. Input is listed up to 20W; the connected adapter and cable determine the negotiated level.
Is a charger included?
A USB-C-to-USB-C cable is confirmed. A wall adapter is not listed as included, and the exact cable length or rating is not published for this package.
Why does wireless charging feel warm or slow down?
Coil alignment and wireless conversion create heat. The phone or power bank can reduce power for temperature control; remove an interfering case, ventilate the setup and disconnect if heat is excessive.
Can I take it on a plane?
The pack is labelled 37Wh, but that is not automatic travel approval. Keep it in cabin baggage, protect it from damage and short circuit, and check current airline, airport and destination rules before departure.
