Best Power Banks of 2025

"I bought this right before a trip and fully charged it. Unfortunately, when I tried to use it, it had no charge. After returning home, I still faced the same issue. It's disappointing because I've had great experiences with other Anker products. Fortunately, they offered me a refund, which I appreciate."

"Overall, I'm pleased with this charger! My classic car lacks charging outlets, so this has been perfect for keeping my phone powered. I did notice it slowed down a bit when it got hot, but it works great otherwise. It's well-made and very portable!"

"I purchased this on May 1st, 2023. While it shows as fully charged, it doesn't charge my phone at all. I've had a good experience with another Anker charger that's still functioning after 6-7 years. I'm hoping they can help with this one."

"I did my research, and this power bank is perfect for my needs. As a high school English teacher, I rely on my iPad daily, and this charger is light, compact, and powerful. It arrived with a 60% charge, and it works flawlessly with all my Apple devices. Highly recommended!"

"For my trip to Thailand, I needed a portable charger that could handle multiple devices. This little charger exceeded my expectations—small, efficient, and it even has an emergency light! It held up beautifully over two weeks, keeping my family connected."

"I've been using the INIU Portable Charger, and it's a game-changer! It's the slimmest 10,000mAh power bank I've encountered. It charges my phone and tablet quickly, uses advanced safety features, and the LED indicator shows the remaining charge. For the quality, it's incredibly affordable. I highly recommend it!"

"This battery has been a life saver for me! It charges fast, taking about 4 hours. I use it to charge my Chromebook and it provides about 50% extra charge if needed. I can charge my cell phone, a small USB LED light, and a portable fan all at once without any issues. For example, it powers my 7-inch portable fan on low for 12 hours straight. However, using multiple devices does drain the battery faster. I love that it fits nicely in my book bag and the long cord allows for discreet charging at places like the library or coffee shops."

"I bought this for a camping trip, and I tested it with my speaker, iPhone, air pump for my inflatable mattress, and a portable projector. All the items worked perfectly! While I’m not sure how long it will last while camping, the initial tests were successful. Plus, I was impressed with the quick delivery—it arrived in just one day!"

"I had heard others using this battery with their CPAP machines, so I was optimistic. However, during a high school wilderness trip, I charged it fully but only got 1.5 hours of CPAP time each night, which made for a poor night's rest. On the bright side, it's great for charging small devices like phones."

"I was pleasantly surprised by the quick charging of these Miady chargers. They took no more than two hours to reach full power, and I was able to charge my phone from 10% to full in about 50 minutes. The fast USB-C connections make a significant difference!"

"These power banks are a game-changer! The 10,000mAh capacity keeps my devices charged all day, whether I'm using my iPhone or Galaxy. The USB-C fast charging is super handy and gets the job done quickly. They're also so lightweight and easy to carry!"

"I recently bought this two-pack, one for my husband and one for myself. While one works great, the second one doesn’t seem to function at all. It lights up briefly while charging, but then goes out. I hope the one that works continues to last!"

"I purchased the INIU Portable Charger and it has quickly become one of my favorite tech investments. With its massive 20000mAh capacity, I can charge my phone multiple times before needing to recharge the power bank itself. The fast charging features, thanks to PD 3.0 and QC 4.0, are fantastic. I appreciate its versatility with multiple ports, allowing my family to charge several devices at once. The LED display is a nice touch, showing me the remaining charge. Overall, this charger offers incredible value for the price!"

"I got this power bank last year before going to Europe, and it replaced my older ones that couldn’t keep up. It charges my phone faster than my regular charger and I can plug in three devices at once. It has saved me countless times during my travels, and I keep it in my purse for daily use. It does take some time to recharge itself, but the battery level display is handy, and it holds its charge well when not in use."

"After two weeks of using this charger on a trip, I can confirm it holds a lot of charge! I found it to be good for about three charges for my iPhone 15 Pro. Using my own USB-C cable, it charges quickly, while the included cable takes longer. I appreciate the included carrying bag and the flashlight feature. While it is a bit heavy, it feels sturdy and durable."

“I bought two of these for a recent trip, and they worked well. Handy iPhone size that can charge my phone throughout the day. I will probably keep one in each vehicle for travel. Good product that I would recommend.”

“I recently purchased the Anker PowerCore 10K after hearing rave reviews. Compact and efficient, this power bank has become an essential part of my travel gear. Its dual USB ports allow charging two devices at once, which is a game-changer for me.”

“I bought this portable charger for my travels. It's slim and compact, looks good, and charges my iPhone fairly quickly. I personally would prefer two output ports to charge multiple devices simultaneously, but overall, it gets the job done well.”

"When I first received the power bank, I thought it might be a bit too large. However, after using it several times over the past few months, I've realized how valuable that 'extra juice' has been. The slight weight I initially noticed has become unimportant. Now, we take it with us everywhere, and I truly appreciate the peace of mind knowing we're always powered up!"

"I recently got the OHOVIV Portable Charger, and it has truly surpassed my expectations. The 22.5W fast charging is incredibly efficient, allowing my phone to charge from nearly empty to full in no time. With its massive 50000mAh capacity, I easily get at least five full charges, ideal for long trips or busy days. The LED display is a great touch, showing real-time battery levels, and the two USB ports let me charge multiple devices simultaneously without sacrificing speed. I highly recommend it!"

"I bought this power bank with low expectations, but it works wonderfully! It’s a bit heavy, but considering all my devices need charging, I can manage. I was able to charge two dead phones in just 40 minutes!"

"I didn't have high expectations initially, but I was pleasantly surprised. It charges my iPhone 12 quickly, and I appreciate the built-in cables and extra ports. The digital screen indicating the battery percentage is really convenient!"

"This portable charger is incredibly versatile! I used it on a trip with friends who had various phone types, and it worked perfectly for everyone. The size is perfect for travel, and it’s become an essential item for me."

"I’ve bought three of these power banks now! They hold charge well, can charge multiple devices simultaneously, and eliminate the need for extra cables. Plus, the different colors help us identify our chargers easily!"

"I really like this charger, but there are a few things to consider before purchasing. It's portable and can fully charge my phone up to 3 times on a single charge, making it very functional and valuable. However, it's slightly bulky and heavy. I noticed that it does get warm when charging, and if my phone reaches 100% but I forget to unplug it, the battery drains a bit. Overall, it’s very convenient and saves me from being near an outlet."

"I decided to get the Anker Zolo Power Bank for an airline trip and it worked wonderfully. While it may not fast charge high-end devices like Samsung Galaxy Ultra or Pixel Pro, it easily fast charged my Pixel 9. I love that it includes a USB-C cable and has an extra USB port, both compatible for charging devices at 30 watts. Its durability and 20000mAh capacity made it my main charger for three devices, and I never felt worried about it breaking."

"Anker is my favorite brand for electronic accessories. This charger is the perfect size and charges my phone quickly. I love the convenience of the charging cord acting like a lanyard, meaning I don't need to carry an extra cable. It functions well, seems durable, and I appreciate the digital screen that shows the battery percentage."

"I purchased this power bank to replace one that had gone bad, and I'm glad I chose Anker. Its 60,000mAh capacity allows me to charge multiple devices without needing to plug into a wall, which is great during blackouts. The emergency light is a fantastic feature that really helps during outages. I also love the smart display that shows me battery status and charging times. My only suggestion would be to include a small compartment for storing cords."

"This power bank has been a lifesaver during the recent hurricanes on the East Coast. Its 87W output easily powered our essential devices for days without power. It's portable, durable, and recharges quickly, making it perfect for emergencies. I highly recommend it for anyone needing a reliable backup power source."

"I love Anker products, but I found this one a bit disappointing. While it's great for charging one device, if I plug in another, the charging speed decreases dramatically for all devices. Despite that, its durability between charges is impressive, and one charge lasts a long time."
