Top 4 Best Laptop Power Banks for 2026 – Expert Tested

Customer Review: “Really impressed with this battery. I have had a few goalzero products in the past and still like them but this battery takes mobile power to another level. The information screen, for being so small, provides allot of information about battery temperature, the amount of time the battery will operate at current draw and even a menu system. I have a windows surface pro and the battery came with a cable for my laptop. I can go to my local Starbucks and sit there working for a few hours. I have also used it on a flight and in the airport. There allot of charging options including a USB option. I have a 14watt goalzero solar panel that does charge the battery through the USB connector cable. The battery construction appears very solid and just says “quality”. The goalzero 100watt will provide a longer time frame amount of power but next to the Omni charge (73watt hours) it just does not have the same geek street creed (if there was such a thing). Also the Omni charge has a smaller footprint in my bag and comes with a 110 volt ac connection unlike the Goalzero which is an additional purchase and takes up alllot more space in your backpack. If you have a dedicated compartment in your backpack for the Omni charge then you will not need the case but if you going to put it in the main compartment or with other pieces of gear then definitely get the case. Just to avoid the possibility of turning it on while everything jostles around back there.”

Customer Review: “I live in Puerto Rico. Our island got hit pretty hard when Hurricane Maria passed. 45+ days after, things are slowly coming back online, but light is not expected to reach where I live for a month or 2. I’m a college student and this battery is the reason I can charge my devices and my computer with no problem. With the added feature of being charge from any other external batteries or a solar panel, this has saved my college life by providing energy to my computer, cellphone, iPad, etc. I work in a hotel in the capital, and the battery charges in less than 2 hours. I can leave it alone and when my shift is over is at 100% ready to go back to where I live where there is no electricity. This is literary a lifesaver. If you want quality, this is the best battery you can buy and the most versatile.”

Customer Review: “I bought this UGREEN power bank mainly based off the specs of my MSI Raider A18 HX (power gaming laptop) so I’d know it would work for anything weaker — specifically my older school laptop that always dies halfway through a 3-hour cyber security lecture. I have no access to a power strip during class, so I needed something that would at least extend my battery life.My hope was that this power bank would slow down the battery drain. It honestly exceeded my expectations. My Raider normally uses a 330W brick, so I 100% knew no portable power bank was gonna fully power that monster under heavy load — but this thing is actually gaining battery % while I’m using the laptop. I expected to still lose power, just slower. Nope — it’s actually charging while being used, which blew me away.One important thing: if you want this to charge a laptop at high wattage, you NEED a USB-C PD 3.1 cable that is E-marked (5A). The included cable is nice, but for max power to the laptop you need a cable rated for it. I grabbed a 240W VisionSync cable with an LED display so I could literally see the wattage in real time — and it confirmed the UGREEN was pushing ~120–130W into my laptop. The small drop vs 140W is likely just cause I bought the 6ft cable instead of the 4ft (long cables = slightly more power loss).Anyway — this thing is smaller than I expected, looks clean, charges fast, truthful with its advertising for wattage transfer, and honestly feels like a premium device. For reference I bought it on 10/31/2025 on sale for $64.99, and I feel like it easily punches in the $120–$140 category in terms of value.If this thing ever fails, I’ll edit this review, but so far so good — super happy with this purchase.In my first picture, I have it showing rate of wattage going through to my laptop using a cable like I mentioned before. In my second picture, I am demonstrating the input wattage transfer speed- the speed at which the power bank itself is charging. Both were very good and better than what I expected with the length of my cable. I truly believe most power banks lie about the power of their devices, but I am happy to declare that UGREEN is legit.”

Customer Review: “A powerhouse portable charger—does it truly deliver 145W fast charging and long-lasting battery life? This UGREEN Nexode lives up to the hype. It features 145W total output, ensuring rapid charging for laptops, tablets, and phones. The dual USB-C ports (140W & 100W) plus a USB-A port (22.5W) allow for convenient multi-device charging. The massive 25,000mAh capacity provides multiple full charges for high-power devices, and the TFT digital display offers real-time battery level, voltage, and charge time estimates. It charged my MacBook Pro from 0-56% in just 30 minutes—compact, powerful, and perfect for travel! For a high-performance power bank that delivers serious charging power, this is a top-tier pick!”

Customer Review: “This is an awesome device. After some quick tests I can say it fully meets my needs and expectations. Yes, it is expensive, and at $150 I didn’t think I could justify it. I got it on sale for $100 and I believe it was definitely worth it.The display is fantastic and really provides all the information you need in order to know what is going on with the inputs and outputs.My main use will be for charging the 50wh battery in my Surface Pro 8. The Anker 737 will charge it at a 55w rate via either of the two Thunderbolt ports (the supplied Microsoft charger is rated at 60w through the Surface connector), and it appears that the conversion efficiency is about 80%, meaning that it can fully charge the Surface and have capacity left over to charge a phone or two.(An interesting note about conversion efficiency based on some quick tests and calculations: If I charge my Surface Pro 8 from my Jackery 300’s PD port, it takes about 60wh to fully charge the 50wh battery. It appears that the Anker 737 will need to supply almost 70wh to fully charge the 50wh battery. If I connect the Microsoft AC adapter to the Jackery 300’s AC port and charge the Surface that way, it requires about 90wh to fully charge the 50wh battery. The more up and down conversions you do, the more you lose.)The supplied cord is rated for 140w and is 60cm long (NOT 6 cm as some have said), or about two feet.I had limited success with pass-through charging, YMMV. I connected a 45w charger and the Anker started charging at 42w. Then I connected a phone, which started charging at 10w, but the input to the Anker then dropped to an identical 10w. A different charger and a different load might give different results, I don’t know.Others have complained about having difficulty charging DJI batteries. Here’s what I think is going on (my best guess, anyway): I have the Mini 2 battery charging hub and three batteries. The hub appears to be happiest with an input of 12v, 1.5a. (The supplied DJI charger is rated at 9v, 2a and 12v, 1.5a.) USB-C PD 3.1 does not appear to support 12v, and when connected to the hub, the hub and the Anker can’t seem to negotiate an 18w charging rate at 9v. HOWEVER, when I connect the hub to the Anker’s USB-A port using the supplied DJI cable all is well and the hub charges at 18w.Some users have panicked over the USB-A port showing 0.1a with no load connected. Anker explains this on their support page (which takes some digging to find). 1. Make sure Trickle Charge mode is off (tap the button twice). 2. Wait two minutes after disconnecting a load from the USB-A port. 3. Relax.Some users have experienced less than expected charging rates. Not all USB cables are created equal. (In fact, back in the early days of USB-C there were some cables that didn’t meet the standard and were risky to use.) Make sure your cable supports the rate your device requires. I bought a six foot, 140w Anker cable to go along with the 737. That, plus the cable supplied with the 737, should meet all my needs.”

Customer Review: “This power bank is extremely reliable and well-made. The 24,000mAh capacity provides plenty of power, and it charges devices quickly and efficiently. The build quality feels solid and premium, exactly what you expect from Anker.The display is useful for monitoring battery status, and having multiple ports makes it convenient for charging more than one device at a time. Great for travel, work, or everyday use.Overall, an excellent power bank with strong performance and dependable quality.”

Customer Review: “The functionality on this is amazing! It has several sockets and phone charge outlets. We used it on our camping trip and it did not disappoint. We charged it at home and it was easy to use.We were able to charge the phones, power a mini fridge, lights and some tablets/laptops. We came home and still had energy left ! It seems to have an excellent run time and battery life. The portable battery is not that big, nor very heavy and we definitely prefer it over a generator. I’m planning to get the solar pads too. Im not sure about the lifespan of this kind of item but the box is very well made and seems great quality.”

Customer Review: “Background: Long time Ecoflow customer going back to Delta Pro pre-launch days. Have a few other of the Delta product line including Delta Pro, Delta Pro Extra Battery, Delta Max, Delta 2 Max, Delta 2 (950). Promoted the product through the family and everybody has atleast one in the Delta series.TL:DR: The Delta 2 has a robust inverter for it’s weight class. Capacity can be expanded if additional runtime is needed. Solar panel is also a solid product, getting high 80% efficiency in mid winter. Will update again during sunnier weather. For the size and weight a solid product pair for mobility.The Good Delta 2: Solid product with impressive product warranty, robust battery chemistry, and monster of an inverter for the weight package. Any 5-15P corded appliance you can throw at it should be able to run with ease with the only concerning point being runtime depending on the wattage drawn which can be supplemented if I get the Delta 2 extra battery.The Good 220w Solar Panel: Solar panel yielding 80% of rated output in winter weather, looking forward to seeing what this thing can do during the summer with clearer skies and longer days.The Not a Fan Of: Super minor and personal preference but not particularly keep on the elastic bands for the 220w. Have other mobile solar panels that are less temperamental and prone to kick back.Usage Scenario in photo: No need to worry about where an outlet is for a backyard cook out. Plugged in a electric fryer (~1200w) only used for 30 mins, ICECO G20 (all day), and the ECOFLOW Multifunctional Outdoor Camping Light. Delta 2 Unit able to handle all 3 devices and with the additional charging from the panels had enough to keep lights on through the night.”
