The Samsung Galaxy Tab S8, still a robust and efficient tablet, does not necessarily warrant upgrading to newer models as minor improvements are minor. Given its large size and high-spec features, the Tab S8’s battery can deplete quickly, especially during portable use. For charging the Galaxy Tab S8 Plus or Tab S8 Ultra, I have selected top power banks suitable for these models. While all Tab S8 models support PPS 45W fast charging, not all recommended power banks have this feature. Instead, they focus on providing a good charging speed, typically around 18W, with various battery sizes to meet different needs.
ROMOSS PEA30 30,000mAh Power Bank
This ROMOSS PEA30 power bank is one of my most recommended portable chargers because it has a large battery and fast charging from its ports. The 30,000mAh battery can charge any model of the Galaxy Tab S8 to full power at least once, and you can still have spare power to use later; this means a lot considering the base Tab S8 has an 8,000mAh battery and the highest tier Tab S8 Ultra model has an 11,200mAh battery. So, the ROMOSS PEA30 power bank can be reliable for a few days, depending on how heavily you use it.
Charging power from the ports matches the battery because the power bank has a 30W USB-C PD port and two USB-A ports. You can fast charge the Tab S8 via the USB-C port, and in my review of the ROMOSS PEA30 power bank, I found that you get the fastest charging speed when charging one device at a time, so you should charge the Tab S8 alone from this power bank to get an optimal charging rate. Also, using the USB-C port to recharge the power bank faster would be better because it has a 30W recharge speed. Watch my video review of the ROMOSS PEA30 30,000mAh Power Bank for a detailed look at its features and performance.
iWalk LinkPod USB-C Power Bank
The iWalk LinkPod power bank is what I consider to be the opposite of the ROMOSS PEA30 power bank because this charger has a much smaller battery, but that is also what makes it so small and lightweight. The iWalk power bank has a 4,800mAh battery, so this is the type of power bank you should get if you want to charge your Tab S8 just enough to get you through the day because the battery size is not enough to charge the Tab S8 nearly to full power. Also, if you’re searching for a power bank that you can more easily fit into a pocket or purse, this power bank can easily do that.
Design-wise, the iWalk LinkPod power bank has a USB-C connector, so you plug the entire power bank into your Tab S8, and you can recharge the power bank by plugging it directly into a wall charger. The USB-C connector has a 20W power delivery charging speed to charge the Tab S8 fast. In my review of the iWalk LinkPod power bank, I recharged the power and charged my Note 9 simultaneously, so this power bank has pass-through charging. Check out my video review of the iWalk LinkPod USB-C Power Bank to see it in action.
UGREEN 145W Power Bank
The UGREEN 145W power bank can be reliable for charging the Tab S8 and nearly a USB-C chargeable laptop. This UGREEN power bank has a 145W max output, two USB-C ports, and one USB-A port. 100W of Power Delivery can always be used from the USB-C 1 port, and you can use 45W of PD from the USB-C 2 port at the same time; this makes it possible to fast charge your Galaxy Tab S8 from the USB-C 2 port while also charging a laptop from the USB-C 1 port. Not many power banks can charge a laptop and another device simultaneously.
In reviewing the UGREEN 145W power bank, I could charge my Lenovo Flex 5 laptop and fast charge my Note 9 simultaneously. The 25,000mAh battery of this UGREEN power bank is another reason to get it because it’s a lot of power that can charge the Tab S8 to full power once, and you can still have power to use later. Watch my video review of the UGREEN 145W Power Bank for an in-depth analysis.
Baseus Blade 100W Power Bank
The Baseus Blade power bank is one of the few on the market with PPS, so you can super fast charge your Tab S8 with the power bank. This Baseus power bank has two USB-C ports and two USB-A ports. The max Power Delivery output is 100W, but that can only be used if you’re only charging one device from the power bank, so to fast charge your Tab S8, I recommend charging it alone to utilize the PPS fast charging. The 20,000mAh battery is a decent amount of power to charge the Tab S8 to its full power at least once.
In my review of the Baseus Blade 100W power bank, I could see the voltage and amperage on the screen at the top of the power bank, so you can see how fast your Galaxy Tab S8 is charging directly on the power bank. Discover the capabilities of this power bank in my video review of the Baseus Blade 100W Power Bank.
INIU 65W 25,000mAh Power Bank
The INIU 65W power bank is another solid option for charging the Tab S8 while you’re going through your day; with it having a 25,000mAh battery, charging your Tab S8 to its full power and extending battery life for more than a day won’t be a problem. The charging power from the ports is also great because the power bank has two USB-C ports and one USB-A port; one USB-C port has a 65W output, and the other has a 30W output. The 65W USB-C port does feature PPS to charge the Tab S8 faster.
In my review of the INIU 65W power bank, my Lenovo laptop would charge slower from the USB-C 1 port when I had other devices charging simultaneously. So, it would help to charge your Tab S8 alone from this power bank to get the best charging speed. Learn more about its charging efficiency in my INIU 65W 25,000mAh Power Bank video review.
Final thoughts about my choice of Power Banks for Galaxy Tab S8
The Galaxy Tab S8 is a powerful tablet that will stay that way for years, but the battery drain that can happen when you’re heavily using the tablet will always be apparent. The good news is that you have a lot of options when it comes to portable power to choose from for the Tab S8 because you can go for the ROMOSS PEA30 power bank that has a 30,000mAh battery size or an iWalk LinkPod power bank that is comically small and has a small battery but has impressive portability. The power bank you choose is based on your powering and portability needs.
