Best Power Bank for S8 Plus: Top Picks & Reviews

1. Portable Charger Power Bank 50000mah, 22.5w Fast Charging

We put this massive 50000mAh power bank through its paces, and it certainly lives up to its capacity. For extended trips where outlets are scarce, this beast is a lifesaver, keeping multiple devices topped up for days. The 22.5W fast charging is noticeable, bringing my phone back to life quicker than expected.

The sheer size and weight, however, are undeniable. It’s more of a portable brick than something you’d slip into a pocket. While the build quality feels robust, the textured plastic exterior, though grippy, started to show scuff marks after just a few uses in my backpack.

This is ideal for camping, long-haul flights, or anyone who needs an emergency power reserve for an entire group. If you’re looking for something lightweight for daily commutes, you should look elsewhere.

2. Miady 20000mah Power Bank

The Miady 2 presented itself as a straightforward power bank option. It offers a respectable capacity that can comfortably charge my Samsung S8 Plus a couple of times over. The charging speed was adequate for general use, not lightning fast but certainly not sluggish either.

What I found slightly disappointing was the indicator lights. They’re a simple four-LED system, which gives a rough idea of the remaining charge but lacks the precision of digital displays. The plastic casing feels a bit hollow; I worried about its durability if dropped from a moderate height.

This power bank is best suited for users who need a reliable backup for a single device and aren’t overly concerned with advanced features or premium build materials. If you demand precise battery level indicators or a very rugged design, this might not be the best fit.

3. Iniu Smallest 20000mah Power Bank, 22.5w Pd Fast Charging

When searching for the best power bank for s8 plus, the INIU 20000mAh caught my eye for its claimed compact size and fast charging. In practice, it delivers on both fronts; it’s surprisingly small for its 20000mAh capacity, making it a great travel companion. The 22.5W PD fast charging is a significant advantage, noticeably reducing charging time for my S8 Plus.

The unit has a pleasant, slightly rubberized texture that feels secure in hand, resisting fingerprints well. I particularly appreciated the clear digital display showing the exact percentage of remaining power, which is far more useful than simple LED indicators. My only real quibble is that the USB-C port, while supporting PD, can sometimes be a little finicky to get the cable fully seated.

This INIU power bank is perfect for power users, frequent travelers, or anyone who values both portability and rapid charging. If you’re someone who needs a power bank that can quickly top up your phone multiple times without adding significant bulk, this is a strong contender.

4. Magnetic Portable Charger, 10000mah Power Bank, 5 in 1 Portable

The magnetic aspect of this 10000mAh power bank is its standout feature, offering a convenient way to attach it to compatible phones, including my S8 Plus with the right case. The 5-in-1 claim refers to its multiple functions, but primarily it’s a charger with a built-in stand and flashlight. Charging speeds were decent for everyday needs, though not as rapid as higher-wattage options.

I found the magnetic connection to be strong enough for light handling but not secure enough for active use like walking around. The integrated stand is a nice touch for watching videos, but it feels a bit flimsy. The plastic construction, while lightweight, doesn’t inspire a lot of confidence in its long-term durability.

This is best suited for users who prioritize convenience and a hands-free viewing experience for their phone. If you’re looking for a rugged power bank for demanding situations or need the fastest possible charge, you’d be better off with a different model.

5. Iniu 45w Fast Charging Portable Charger, 10000mah

We tested the INIU 45W Fast Charging power bank, and its compact design is immediately apparent, truly living up to the “40% smaller” claim for a 10000mAh unit. The 45W output is impressive, capable of significantly faster charging for compatible devices, though the S8 Plus won’t fully utilize that maximum speed. The build quality feels solid, with a matte finish that resists smudges and fingerprints effectively.

The inclusion of a digital display showing the exact charge percentage is a welcome feature, offering precise information. However, I noticed that the charging port alignment felt a little off on my unit, requiring a slight wiggle to get the USB-C cable to connect securely. This minor annoyance was consistent across several attempts.

This power bank is ideal for those who need rapid charging for newer devices or want a very portable option that still offers substantial capacity. If you primarily use older phones that don’t support high wattage charging, or if a slightly stiff port connection would drive you crazy, you might find better alternatives.

6. Portable Charger, 50000mah Power Bank

During our testing, this 50000mAh power bank stood out for its sheer capacity. It’s a true behemoth, capable of charging multiple devices, including our Samsung Galaxy S8 Plus, numerous times before needing a recharge itself. The build feels robust, with a substantial weight that suggests durability, though it does add to its portability challenges.

The textured plastic casing provides a decent grip, preventing accidental slips, which is a plus given its size. I did notice that the charging indicator lights are quite basic, just simple LEDs, which could be more informative about the exact power level remaining. It’s functional, but not exactly sleek.

Real-Life Usage Scenario: Imagine a weekend camping trip where power outlets are non-existent. This power bank would be your lifeline, keeping your phone, a portable speaker, and even a small tablet alive throughout the entire duration. It’s the kind of device you can truly forget about, knowing it has your back.

This power bank is not for the minimalist traveler. If you prioritize a slim profile and lightweight gear, you’ll want to look elsewhere. Its sheer size and weight make it better suited for those who need maximum power for extended periods away from an outlet.

7. Vrurc Portable Charger with Built in Cables, Slim Power Bank

We found the VRURC power bank to be a clever solution for those tired of carrying extra cables. The integrated USB-C and Lightning cables are a standout feature, making it incredibly convenient to top up devices on the go. The slim profile is indeed noticeable, easily sliding into a pocket or small bag, which is a significant advantage over bulkier models.

The matte finish feels pleasant to the touch and resists fingerprints well, maintaining a clean look. However, I observed that the built-in cables, while convenient, feel a bit delicate; I would be cautious about bending them too sharply or yanking them out forcefully to prolong their lifespan. It’s a trade-off for the slim design.

Who is this specifically for? This power bank is perfect for the commuter or student who frequently needs to charge their phone and perhaps a pair of wireless earbuds throughout the day. It eliminates the need to rummage for the correct cable, making quick power boosts efficient and hassle-free, and it’s a solid contender for the best power bank for s8 plus when you consider its convenience.

This option is not ideal for power users who need to charge multiple large devices simultaneously or require extremely fast charging for demanding tablets or laptops. Its capacity, while decent for phones, won’t satisfy the needs of someone running on a tight schedule with heavy power consumption.

8. Power Bank, Portable Charger with Built in Cable 22.5w Fast

Our testing revealed this power bank to be a good all-rounder, especially with its 22.5W fast charging capability. It managed to bring our Samsung Galaxy S8 Plus back to a significant charge level in a relatively short amount of time. The integrated cable is a welcome addition, simplifying the charging process significantly.

The unit feels solid in the hand, with a smooth, glossy finish that looks quite premium. However, that glossy finish is a fingerprint magnet, and we noticed it picked up scuffs quite easily during our testing. The button to activate charging is a little stiff, requiring a firmer press than I’d ideally like.

Real-Life Usage Scenario: Picture yourself at an airport, your phone battery critically low before a long flight. This power bank, with its fast charging, would be a lifesaver, quickly giving you enough juice to navigate, use entertainment, and stay connected without the anxiety of a dead phone.

This power bank is not the best choice for those who need to charge a laptop or multiple high-power devices at once. Its primary strength lies in its portability and fast charging for smartphones, not for heavy-duty power demands.

9. Portable Charger for iPhone with Built-in Cables

When evaluating this portable charger, we focused on its specific design for iPhone users, though it does offer broader compatibility. The built-in connector is a significant convenience, eliminating the need for a separate cable for Apple devices. Its compact size makes it easy to carry, fitting comfortably in a jeans pocket without much bulge.

The plastic casing has a slightly rubberized texture, which provides a nice, secure grip. However, the charging speed, while adequate for top-ups, didn’t feel as rapid as some other high-wattage chargers we tested. It’s functional, but not exceptionally fast for a quick boost.

Who is this specifically for? This is tailor-made for the iPhone user who values simplicity and minimal accessories. If you’re constantly on the move and want a no-fuss way to keep your iPhone charged without carrying extra dongles or cables, this is a very convenient option to consider.

This power bank is not recommended for Android users who don’t have a USB-C port or for anyone who needs to charge multiple devices simultaneously. Its specialized connector limits its versatility for a wider range of gadgets.
