- Uses 21700-class cells and a flame-retardant V-0-rated housing claim shown in the gallery.
- 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 connector direction, supported protocol and safety limits in view.
Compatible laptop support. Use USB-C1 for a USB-C laptop that accepts up to 100W, with the included 100W cable and enough battery remaining.
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 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.
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.
- 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.
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 for this 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.
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.
- 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 5A cable and fully seated connectors.
Check before ordering
Confirm connector direction, required protocol, power profile, cable length and package needs before choosing by appearance.
- Confirm 20,000mAh / 72Wh is the required balance of runtime, size and transport rules.
- Confirm the highest-rated output port matches the device’s input protocol and wattage.
- Confirm the included cable rating and whether a separate wall charger is needed.
- Confirm simultaneous-device power sharing is acceptable for the planned setup.
- Confirm the dimensions and weight suit the bag or workspace.
- Confirm airline and destination battery rules if the product will travel.
Care and troubleshooting
Disconnect power before inspection and change one variable at a time when diagnosing a connection.
- Disconnect all cables and wipe the enclosure with a soft, dry cloth. Do not allow liquid or cleaner into a port.
- Store partially charged in a cool, dry place away from combustible clutter; check and recharge it periodically according to the manual.
- If a device charges slowly, test one output at a time, use the highest-rated port, verify cable wattage and compare the device’s supported input profile.
- If the power bank reboots when a second device is attached, disconnect all loads, let it cool, then reconnect the highest-power device first and remain within the shared total.
- If the display seems inaccurate after long storage, complete a normal controlled charge/discharge cycle; stop if the enclosure or temperature appears abnormal.
- A damaged or end-of-life battery should be isolated from metal objects and delivered to an authorised battery service or recycling channel.

Questions buyers ask.
What is the 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 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 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.
