Best Laptop Power Banks and Portable Laptop Chargers for 2022
A portable laptop power bank is an essential purchase for working on-the-go. Here are the best portable chargers worth your hard-earned money.
We know it all too well here at Laptop Mag: your portable powerhouse dies amid some CPU-intensive workload and you’re left with hours of lost effort. There’s nobody to blame but your laptop’s internal battery and yourself for not hitting CTRLS (save).
Luckily, there’s a fix for those awful times when your laptop powers down. The world of portable laptop chargers has exploded (not literally, fortunately) over the last two years, as the need for working on the move has risen. So, rather than praying for a plug at a nearby cafe, you can work completely untethered without fear.
We’ve found the best options in terms of value and reliability and we’ve provided a small guide on the things to look for so you can make the best choice for your and your gadgets. And, if you need any advice elsewhere, check out our laptop buying guide and iPad buying guide, so you can be sure about your purchase decisions.
What to look for in a portable laptop battery charger?
The Intelli ScoutPro does it all — MagSafe wireless charging for iPhone and for either Apple Watch or Samsung Watch, alongside dual 100W USB-C ports, dual USB-A and an OLED display that shows you the current being delivered to your up to 5 devices, this world’s smallest 240W power bank is the ultimate convenience.
And with a 24,000 mAh capacity, included carry case with s for cables and a durable metal build, this is a great option at 189.
Excitrus NitroCharge 120 Pro
The Excitrus NitroCharge 120 Pro is our top recommendation for a laptop power bank. We could talk about the 25,600 mAh battery inside giving you so much capacity for multiple charge cycles. We could also talk about the digital display giving you an accurate percentage level of the battery remaining.
But our favourite two elements are the 100W input and output power delivery — enabling fast charge and juicing up laptops in no time, and the MagSafe charging spot on top! You get the 15W for iPhones, but it also just broader Qi wireless charging too, to that same standard.
DIY Laptop PowerBank
In this project I will show you how to create a Laptop PowerBank. It mainly consists of a Li-Ion battery pack and one buck and boost converter. This way the PowerBank can get charged up through the Laptop power supply and aftewards charge up the Laptop directly to give it an additional run time of 3 hours. Let’s get started!
Here you can find the wiring schematic along with tons of reference pictures of my laptop powerbank. Feel free to use them to create your own powerbank.
You did it! You just created your own Laptop PowerBank!

According to links the LiFePo4 BMS is used with Li-Ion batteries. Those are different chemistries and have different working voltage. For discharge and charge. I do not understand how is it can even work. It should already give problems at first discharge.
This is an awesome project and a must doing it.
Hey I stumbled in this video am so amazed I will like to make one, but how do I charge the battery when it run down.Thanks
So amazing, that’s why i regarded you l as my mentor in electronic eng. I will give it try and share the experience i get. Thanks
The enclosure looks fantastic. Really clean 🙂
i don’t think that it matters. the laptop will draw the required amount of current. all you need to make sure is that the convertor you’re using supports the current draw of the laptop.He only limited the current on the batteries as they have a current limit recommendation and exceeding that can lead to the battery degrading faster than normal or possibly causing fires.
i know this is a late reply but hope it answered your question and helps anyone else out.
EBay links aren’t really helpful as once products are sold the link changes. Perhaps a link to an online retailer with a suggestion to check eBay.
can somebody send me the files seperate
can u up load each part separate because i can not print all at once
Since I am not a EE, I am looking for one who can create a PCB for my powerbank with nand chip on it for prototyping. I know I can order such pcb’s from China for powerbanks but I need an extra function on my device for storage. the measurement of such pcb would be around 150mm/200mm by 1000mm (see pic as a format), double or triple layers. I have a small budget can pay you but let me know your rate.
a better solution would be to increase the laptop battery
That’s a great project. I’m happy to see you included all the safety measures in it.I had the same problem of less working time out of my old laptop battery. So I got a new battery and now if the battery dies, I can hibernate the laptop(it auto hibernate when battery level drops), switch out the battery and continue working. Much simpler method but yours is much cooler 🙂
How To Charge Lenovo Laptop With Power Bank
If you want to charge your Lenovo laptop with a power bank, there are a few simple steps that you can follow.
Step 1: Find the right charging cable for your laptop
The first thing that you will need to do is find the right charging cable for your laptop. This will be different depending on whether or not your laptop has USB-C ports, as well as what kind of charger port it has. Check the manual for your laptop or look online for information about which cables work with it.
Step 2: Use the correct adapter with your power bank
Once you have found the right cable and adapter, plug one end into your power bank and attach it to an outlet. Then plug the other end into your computer’s charging port using an adapter if necessary. Your computer should start charging immediately.
Step 3: Set up automatic updates on your computer’s operating system
The last step in charging your Lenovo laptop with a power bank is setting up automatic updates on its operating system (OS). This ensures that you always have access to new features and security patches when they become available, while also ensuring that any issues reported by other users are resolved quickly so that they do not impact performance or cause problems later on down road
How To Charge Lenovo Laptop With Power Bank
It is possible to charge your Lenovo laptop with a power bank. However, it may take several hours for the laptop to fully charge. Here’s how:
Plug the power bank into an outlet and let it charge for at least two hours before using it to charge your laptop.
Plug one end of the USB cable into your power bank and the other end into your laptop’s charging port.
Turn on your laptop and allow it to fully charge before unplugging the power bank from its outlet or removing the USB cable from its charging port
Can You Charge a Lenovo Laptop With USB?
It’s possible to charge some Lenovo laptops via USB. Check what USB ports you have on your computer. If you have a USB-C connection, it’s possible to recharge through this method providing the charger supports PD (Power Delivery). If you’re not sure, check the ports on your laptop. They often have USB-C displayed on them in small print. Here’s how to charge via USB-C.
It matters which type of USB port you have. You can’t charge your laptop if the laptop only has regular USB-A connections.
If the voltage is lower than the laptop requires, it may still work, but it will recharge at a slower speed.
AC chargers (for laptops without USB-C charging)
There is also the Gravity 500 which allows you to charge your computers, and all your other devices, just like on mains. It can charge all computers, smartphones, connected watches, Nintendo Switch etc. Also small portable fridge and television, for which it is necessary to check the minimum power supply required (max 300 Watts).
Using the Gravity 500 is extremely simple: you plug your laptop’s charging cable (also with EU plug) into it just as you would a regular power outlet.
The Gravity 500 is more expensive and heavier than most USB-C chargers. However, it has a much larger capacity (137,700 mAh / 500Wh) and it also allows for greater compatibility as mentioned above: you can plug in almost any device with a standard power connection. This is a universal power bank, which can work for a wide variety of devices in a wide variety of situations. It also incorporates 4 USB-A ports and 1 USB-C port, a car charger port, AC and DC capability and an on-board display.
The Gravity 500 can be charged from the mains, via car power and at the sun with the Fusion 100 Watts.
The Gravity 144 offers similar benefits, in a smaller, more portable version:
