UGREEN Nexode 100W Power Bank, 20000mAh/72Wh (25188)
UGREEN Nexode 100W Power Bank, 20000mAh/72Wh (25188) is a rechargeable 20,000mAh (72Wh) USB power bank with two USB-C ports and one USB-A port. It is intended to charge compatible USB devices away from a wall socket while clearly showing remaining battery information on its display.
Overview
USB-C1 supports up to 100W output and 65W input, USB-C2 supports up to 30W output, and USB-A supports up to 22.5W output; the system total is up to 100W with dynamic power sharing. 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.

- Protection artwork covers temperature, over-voltage, over-current, short-circuit, over-charge and over-discharge monitoring.
- 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.
Reaching 100W from USB-C1 requires a device that requests the matching USB PD profile and a 5A electronically marked USB-C cable. The included official 100W cable is intended for this role.
USB-C1 can recharge the power bank at up to 65W with a compatible 65W-or-higher USB-C PD charger and capable cable. The wall charger is separate.
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.
Phone and tablet kit
Use USB-C2 or USB-A for smaller devices while reserving USB-C1 for the highest-priority load.
Multi-device workday
Connect up to three compatible devices and expect power to be redistributed within the 100W total.
Carry-on travel planning
The 72Wh rating is the number used for transport checks. Keep the rating readable, protect the terminals and confirm carrier rules before a flight.
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 3 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 that accept standard USB PD at 100W or less; some proprietary or higher-power notebooks can charge below their original adapter rate.
- USB-C handheld gaming systems, cameras and mobile work equipment within the supported profile and total 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.
What this product does
These are the supported functions of this exact product when the complete connection is compatible.
- Stores rechargeable DC energy and supplies negotiated USB charging away from a wall outlet.
- Provides up to 100W through USB-C1 with a 5A cable and compatible device.
- Recharges at up to 65W through USB-C1 with a compatible wall charger.
- Provides separate USB-C2 and USB-A outputs for smaller devices.
- Shows remaining battery information on the built-in display.
- Can charge more than one compatible device within the stated shared-output limit.
- Automatically negotiates supported charging profiles rather than forcing maximum voltage into every device.
What this product does not do
These exclusions distinguish this SKU from visually similar cables, chargers, hubs, audio products and power stations.
- Does not provide an AC mains outlet or act as a UPS/inverter.
- Does not provide wireless charging.
- Does not guarantee the nameplate maximum to every device or every port simultaneously.
- Does not make an under-rated cable capable of high-current USB-C charging.
- Does not replace a device maker’s required charger for firmware updates, recovery or safety-critical use.
- Does not have the same usable output mAh as its internal nominal cell capacity because voltage conversion has unavoidable losses.
- Does not provide 100W independently from every port.
- Does not reproduce proprietary laptop barrel-connector charging without a supported USB-C PD input path.
Choose by function: If the required task appears in this exclusion list, select a purpose-built cable, charger, adapter or power product with the needed interface and rating.
What to do
These habits support reliable charging, data, audio and battery use while reducing avoidable connector strain.
- Use the correct high-rated USB-C port and cable for the most demanding device.
- Keep the battery’s Wh marking readable for transport inspection.
- Charge and discharge on a firm, uncovered, ventilated surface.
- Disconnect and inspect if charging repeatedly starts and stops or heat becomes excessive.
- Recharge periodically during storage and follow the manual’s temperature guidance.
- Check airline rules before every journey because carrier policy can be stricter than the baseline guidance.
What not to do
Avoid these common mistakes even when the plug appears to fit.
- Do not place the power bank in checked baggage.
- Do not use or recharge it inside a closed bag, under bedding or in direct sun.
- Do not puncture, crush, dismantle, burn or expose the battery to water.
- Do not use a swollen, leaking, dropped, cracked or unusually hot unit.
- Do not exceed cable ratings or use loose adapters for high-power charging.
- Do not rely on pass-through charging as a UPS; that role is not verified for this exact product.
- Do not allow keys, coins or metal tools to bridge any port or connector.
Warnings and limitations
Review these electrical, thermal, transport and physical limits before connecting valuable equipment.
- The battery is 72Wh, below the 100Wh threshold in current IATA power-bank guidance. That guidance places power banks in carry-on baggage only, limits a passenger to two power banks of 100Wh or less, and allows airlines to impose stricter rules. Check the operating carrier before travel; never place a power bank in checked baggage.
- Current IATA guidance also restricts onboard storage and use; keep the power bank accessible, not in an overhead locker, and follow crew instructions about use or recharging from aircraft power.
- 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.
- At 100W, under-rated or damaged cables can overheat or limit power. Use a verified 5A cable and fully seated connectors.
- The exact gallery’s “airline approved” artwork is not used because permission is never universal; current carrier and route rules remain decisive.
Stop and recheck: Disconnect power if a connection becomes loose, wet, damaged, swollen, unstable or unusually hot. Never keep reconnecting equipment that shows a safety warning.

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 25188?
20,000mAh nominal, corresponding to 72Wh. Usable delivered energy is lower after conversion and safety reserves.
What is the maximum output?
100W maximum through USB-C1 and up to 100W total. It is conditional on the correct port, compatible device, cable and current power-sharing state.
Can it charge a laptop?
Yes, through USB-C1, for laptops that accept standard USB PD at 100W or less. A 5A E-marked cable is required, and higher-power or proprietary systems may charge slowly.
Can it charge more than one device?
Yes, using its two USB-C ports and one USB-A port; the total is shared and per-port speed can reduce when several outputs are active.
Can I take it on a flight?
Its 72Wh rating is below 100Wh. Current IATA power-bank guidance says carry-on only, a maximum of two power banks of 100Wh or less, and permits stricter airline policy. Check the carrier before travel.
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 included in the official package list. A compatible 65W-or-higher USB-C PD charger is needed to reach the maximum recharge input.
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.
