I sometimes take my laptop with me when I’m out and about so I can do some work or watch movies. However, it can be tricky finding a power socket wherever you are, and even if you do find one, sometimes you’re not sitting close enough to charge your device.
I decided to buy a power bank that could charge my HP Spectre x360 Convertible 13” laptop and Google Pixel 4 XL while I was out and about. I had a little gander on Amazon and based on customer reviews on the site and my positive experience with other Anker products – namely the SoundCore Bluetooth speaker and Soundcore Life P2 earbuds, both of which have excellent battery life – I bought the PowerCore+ 26800 PD 45W power bank which has a USB-C and two USB-A slots and comes with an Anker 60W wall charger and USB-C to USB-C cable.
I carried out four tests to see how well the Anker power bank performed when it came to charging my laptop and phone.
Charging my laptop while working
With 12% battery life left on my laptop, I plugged it into the power bank to charge while doing a bit of work in Word, Excel and WordPress. After working, I watched The Leftovers on Amazon Prime – pretty good TV series about 2% of the world’s population mysteriously disappearing – until the power bank ran dry.
After 2 hours and 20 minutes of charging, the power bank added 78% battery life to my laptop, bringing it up to 90%. Pretty good, considering it was in constant use while its battery was being topped up. With 90% battery life, I could use it for another 5 or 6 hours, depending on what I was doing.
Charging my laptop and mobile simultaneously
I ran the batteries down on both my laptop and phone until they give me a warning that they were about to die – 12% on the laptop and 15% on the Pixel 4 XL – and then started charging them at the same time. With little use on both devices, I charged them until the light on the power bank started blinking, leaving the laptop with 99% battery life and the phone with 98% after 2 hours and 25 minutes.
I could have left them charging until the power bank died but didn’t want to completely discharge it and reduce its overall battery life.
Charging only my laptop while switched on but not in use
Again, I started charging my laptop when the battery level reached 12%, which took 2 hours 35 minutes to reach 100%. However, it consumed all of the power bank’s battery to fully charge the laptop, compared to being able to almost fully charge both my laptop and phone simultaneously.
Not sure why this is but based on these two tests, I would charge both devices at the same time in order to get the most out of the power bank.
Charging my mobile with light usage
I tested to see how quickly my phone would charge using both the USB-C and USB-A cables. Using the USB-A cable, it took on average 2 hours 30 minutes to charge while it only took 1 hour and 40 minutes on average using the USB-C cable.
With 100% battery life in the power bank, I managed to charge my phone fully five times with little usage. I was expecting to get at least six charges out of it, considering it could charge my laptop and phone simultaneously, but five charges will keep my phone running for about five or six days without being plugged into the wall.
Recharging the power bank
Recharging the Anker power bank is surprisingly quick, taking only three hours on average for each recharge, compared to about half a day for the PowerCore 20100 which I also own.
Should you buy this Anker power bank?
If you need to keep your laptop and mobile alive while you’re travelling or out and about, I would definitely recommend getting this power bank by Anker.
However, if you need a power bank just to charge your phone with on a daily basis while you’re out shopping in town, I would get something a bit lighter because at 730 grams, the Anker power bank can add some serious heft to all the shopping bags you’ll be carrying around town.
