7 Best Power Banks for Black Friday Deals 2025
Black Friday 2025 is here, and it brings some fantastic deals on power banks that can keep your devices charged all day long.
Whether you travel often, work remotely, or just need backup power for your smartphone, finding the right portable charger matters more than ever.
The market offers everything from compact 5,000mAh options to massive 80,000mAh battery packs with multiple charging ports.

Understanding Power Bank Capacity and Your Needs
Power bank capacity measured in mAh (milliamp hours) determines how many times you can charge your devices. A standard iPhone 15 has about 3,350mAh battery capacity. A 10,000mAh power bank charges it roughly twice, accounting for energy loss during charging.
Your usage patterns determine what capacity makes sense. Daily commuters might only need 10,000mAh to top up their phone once or twice. Long distance travelers benefit from 20,000mAh or higher for multiple days without wall outlets.
Weight increases with capacity, so balance power needs with portability. A 50,000mAh power bank weighs significantly more than a 10,000mAh model. Consider where you’ll carry the power bank and how much extra weight you want in your bag or pocket.
Fast Charging Technology Explained Simply
Fast charging technology pushes more power to your device in less time. Standard 5W charging takes hours to fill a phone battery. Modern 20W to 30W charging reaches 50% in about 30 minutes, making a huge difference when you’re in a hurry.
USB C Power Delivery (PD) and Qualcomm Quick Charge represent two main fast charging standards. Most recent phones support one or both technologies. Check your phone’s specifications to know what charging speeds it accepts.
Higher wattage doesn’t damage devices because phones only draw what they need. A 87W power bank charges a 20W phone at 20W, not 87W. The extra wattage capacity means the power bank can charge laptops and other high power devices too.
Built-In Cables vs Separate Cables
Power banks with built in cables offer convenience by always having a charging cord available. You never forget cables at home or lose them in your bag. This design simplifies travel packing and reduces the number of items to track.
Separate cables provide flexibility to replace damaged cords or use different cable types. Built in cables that break require replacing the entire power bank. Consider your typical usage scenarios when deciding between integrated or separate cable designs.
Some power banks offer both built in cables and additional ports for separate cables. This combination provides convenience plus flexibility. The hybrid approach works well for most users, giving options for different charging situations.
Wireless vs Wired Charging Benefits
Wireless charging provides cable free convenience, especially with magnetic power banks that attach to iPhones. You can use your phone while charging without cord restrictions. Wireless charging typically delivers 5W to 15W, slower than wired fast charging but convenient for casual use.
Wired charging offers faster speeds and higher efficiency. Less energy gets lost as heat compared to wireless charging. For quickly charging a dead battery, wired connections work better with 20W to 30W speeds.
Many modern power banks include both wireless and wired options. You can use wireless charging for convenience and switch to wired when speed matters. Having both capabilities provides maximum flexibility for different situations throughout your day.
Black Friday Shopping Tips for Power Banks
Compare prices across different retailers before buying. Black Friday deals vary, and the best price might not always appear on Amazon. Check manufacturer websites and electronics retailers for competing offers.
Read recent customer reviews to understand real world performance. Look for comments about charging speed, build quality, and actual capacity. Reviews reveal issues that product descriptions don’t mention, like slow recharging or incompatible cables.
Consider buying during early Black Friday deals rather than waiting until the actual day. Many retailers offer the same discounts throughout November. Popular power banks sell out quickly, so purchasing early ensures you get your preferred model.
Safety Features and Certifications Matter
Quality power banks include safety features that protect your devices from overcharging, overheating, and short circuits. Look for certifications like UL or CE marks. Reputable brands include these protections, while cheaper unknown brands might skip safety features.
Airline approved power banks must stay under 100Wh (watt hours) for carry on luggage. Most power banks under 27,000mAh meet this requirement. Check TSA guidelines if you travel frequently, as non compliant power banks get confiscated at security checkpoints.
Battery quality varies significantly between manufacturers. Premium brands use higher grade lithium ion or lithium polymer cells that last longer and charge more efficiently. Cheap power banks might claim high capacity but deliver much less actual charging power than advertised.
Frequently Asked Questions
How long does it take to fully charge a 20,000mAh power bank?
Charging time depends on the input wattage of both the power bank and your wall charger. A 20,000mAh power bank with 18W input takes about 4 to 5 hours to fully charge from empty. Power banks with 30W input charge faster, reaching full capacity in roughly 3 hours. Always use a wall charger that matches or exceeds the power bank’s input rating for fastest charging times.
Can power banks charge laptops?
Many modern power banks with USB C Power Delivery can charge laptops. Look for models with 45W to 87W output for laptop charging. The power bank needs sufficient wattage to match your laptop’s requirements. MacBooks, Chromebooks, and many Windows laptops charge from compatible power banks, though gaming laptops often need more power than portable chargers provide.
How many times can a 10,000mAh power bank charge my phone?
A 10,000mAh power bank typically charges most smartphones 1.5 to 2 times fully. Energy loss during charging reduces the effective capacity to about 7,000 to 7,500mAh. Phone battery size affects the number of charges you get. Phones with 3,000mAh batteries get more charges than phones with 5,000mAh batteries from the same power bank.
Are solar power banks worth buying?
Solar power banks work best as emergency backup rather than primary charging method. The small solar panels charge very slowly, often taking days of direct sunlight to fill the battery. Solar capability adds peace of mind for camping trips or emergency kits, but don’t rely on solar as your main charging source. Wall charging remains much faster and more practical for regular use.
What does mAh mean on power banks?
mAh stands for milliamp hours and measures battery capacity. Higher mAh numbers mean more stored energy. A 20,000mAh power bank holds twice as much energy as a 10,000mAh model. However, actual charging capacity is lower due to energy loss during the charging process, typically around 70% to 75% efficiency for most power banks.
Do power banks lose charge when not in use?
Power banks slowly discharge even when not actively charging devices. Most quality power banks lose about 2% to 5% of charge per month during storage. Check and recharge your power bank every few months if you don’t use it regularly. This prevents the battery from dropping too low, which can damage the cells and reduce overall lifespan.
Can I take power banks on airplanes?
Airlines allow power banks in carry on luggage but not checked bags. The power bank must be under 100Wh (watt hours) for most airlines. Calculate Wh by multiplying mAh by voltage and dividing by 1,000. A 20,000mAh power bank at 3.7V equals 74Wh, well within limits. Always pack power banks in your carry on bag and check your specific airline’s policies before flying.
