A 5,000mAh power bank is suitable for compact emergency top-ups. A 10,000mAh model is often a practical choice for everyday phone charging.

A 20,000mAh model provides more stored energy for repeated charging. Higher-capacity models, such as 50,000mAh or 60,000mAh, are better suited to ground-based outdoor or backup use.

Explore our Mini Power Banks and High Capacity Power Banks .

Compatibility depends on your device's charging connector, required voltage, charging protocol, and power requirements.

Some Avepower models include built-in USB-C connectors or 8-pin-style charging cables. Others offer USB-A and USB-C ports.

Check the specifications of the product and your device. If you are unsure, contact us with your device model.

Some Avepower power banks support charging multiple compatible devices simultaneously.

The number of supported devices and the maximum combined output vary by model. Charging speed may decrease when several devices share the available power.

Always check the individual port ratings and total output specifications.

No. Depending on the model, a USB-C port may support input, output, or both.

For example, the Avepower T82 lists a USB-C input/output port.

Check your product's exact specifications before assuming two-way charging is supported.

No. The mAh rating describes battery charge capacity, while watts (W) describe electrical power.

Charging speed depends on the output wattage, supported charging protocols, charging cable, and connected device.

A larger-capacity power bank is not automatically faster.

The number of full charges depends on the power bank's stored energy in Wh, your phone's battery energy capacity, and charging losses.

A simple comparison of mAh ratings can overestimate the actual number of charges.

Use the rated watt-hours and allow for power conversion and device-charging losses when estimating capacity.

Connect your power bank to a compatible wall charger using the specified input port or built-in cable.

Check the product's supported input voltage, current, and charging specifications. The charging time varies by capacity, input wattage, and other conditions.

Stop using the product if it becomes damaged or unusually hot.

Yes, but only when the power bank provides the voltage, USB-C Power Delivery profile, and output wattage required by the laptop.

A large mAh capacity alone does not guarantee laptop compatibility.

Check your laptop's charging requirements against the exact output specifications of the power bank.

This function is called pass-through charging.

It should only be used when explicitly supported by the specific model. Not every Avepower power bank supports charging and discharging simultaneously.

Check the product instructions or contact support for confirmation.

Eligible products purchased directly from the Avepower online store may be returned within 30 days after delivery, subject to the applicable return conditions.

Products generally need to meet the condition requirements stated in our Return & Refund Policy .

Contact info@avepower.com with your order number, product model, and reason for the request.

Include photos or videos if your request concerns damage or a product defect.

Please wait for approved return instructions before shipping a lithium battery product.

For change-of-mind returns, the customer is generally responsible for return shipping costs.

For confirmed defective, damaged-on-arrival, or incorrectly shipped products, Avepower will generally cover reasonable return shipping costs, subject to the policy terms.

See the Return & Refund Policy for full details.

Once an approved return has been received and inspected, an eligible refund is issued to the original payment method.

The time required for the refund to appear depends on your bank or payment provider.

Please contact us with your order number if you need an update on a confirmed refund.

Avepower provides a 12-month limited warranty for eligible products purchased directly from its official online store, unless another warranty term is specified.

The warranty covers qualifying defects in materials or workmanship under normal use. It does not generally cover accidental damage, misuse, or ordinary battery aging.

Review our Warranty Policy for conditions and exclusions.

Email info@avepower.com with your order number, product model, purchase date, and a description of the problem.

Include photos or videos where possible. Our team may provide troubleshooting instructions before evaluating a repair, replacement, or other remedy.

Under U.S. passenger aviation rules, power banks must be carried in carry-on baggage only.

Lithium-ion batteries rated 100Wh or less are generally permitted.

Batteries above 100Wh and up to 160Wh require airline approval and are subject to quantity limits.

Batteries exceeding 160Wh are not permitted as ordinary passenger spare batteries.

Check the FAA guidance and your airline's current rules.

Generally not when the power bank's rated energy exceeds 160Wh.

For example, the Avepower DX273 50,000mAh model lists a nominal energy rating of 185Wh, which exceeds the U.S. passenger-aircraft limit.

Check the Wh rating marked on your specific model, rather than relying on its mAh value alone.

Use the following formula:

Wh = mAh × Nominal Voltage (V) ÷ 1,000

For example, a 20,000mAh battery rated at 3.7V has approximately 74Wh.

Always use the actual nominal voltage and energy rating shown in the product specifications.

Stop using or charging the power bank immediately.

Do not puncture, disassemble, crush, or attempt to repair a damaged lithium battery.

If safe to do so, keep it away from combustible materials and follow local hazardous-battery disposal guidance.

Contact Avepower support for product-specific assistance.

Store your power bank in a cool, dry environment away from direct sunlight and excessive heat.

Avoid leaving it in a hot parked vehicle or exposing it to moisture and physical damage.

Follow the manufacturer's long-term storage and periodic charging instructions.
