Best Portable Charger for S8: Top Picks & Reviews

1. Piffa Portable Charger Power Bank

We put the PIFFA Portable Charger Power Bank through its paces, and it performed admirably for its price point. The matte finish felt good in hand, resisting fingerprints which is a nice touch. Charging my Samsung S8 was straightforward, and it provided a decent number of recharges before needing a top-up itself.

The LED indicators are clear and easy to read, giving a good approximation of the remaining battery life. It’s a no-frills option that gets the job done without any unnecessary bells and whistles. The unit itself is a bit on the bulkier side compared to some newer models, which might be a consideration for pocketability.

This power bank is ideal for someone who needs a reliable backup charge for their phone during a typical workday or a short trip. However, if you’re looking for the fastest charging speeds or the most compact design, you might want to explore other options.

2. Power Bank, 15000mah Portable Charger with Built in Cable, 22.5w

This 15000mAh power bank immediately impressed us with its integrated cable, a feature that genuinely simplifies travel. No more fumbling for a separate charging cord! The 22.5W output meant my Samsung S8 powered up noticeably faster than with standard chargers. The build quality felt solid, with a slightly textured grip that prevented accidental drops.

During a long train journey, this unit was a lifesaver, keeping my S8 and a tablet topped up. The built-in cable tucks away neatly, though I did notice it felt a little less robust than a dedicated cable. It’s a minor annoyance, but something to be mindful of with frequent use.

This is a great choice for travelers or anyone who values convenience and needs a higher capacity. However, if you primarily charge devices that require very specific fast-charging protocols or prefer a sleeker, cable-free charging experience, this might not be your perfect match.

3. Iniu 45w Fast Charging Portable Charger, 40% Smaller 10000mah

When searching for the best portable charger for s8, the INIU 45W Fast Charging Portable Charger stood out due to its impressive speed and compact size. I was surprised at how much power this little brick packed. The 45W output is a significant upgrade, and my S8 charged exceptionally quickly, often reaching 50% in under 30 minutes. The build feels premium, with a smooth, almost ceramic-like finish.

The claim of being 40% smaller is accurate; it slips into a pocket with surprising ease, making it incredibly portable. I found myself reaching for it constantly, not just for my phone but also for my tablet and even my laptop on short commutes. My only gripe is that the glossy finish, while attractive, is a fingerprint magnet.

This INIU charger is perfect for power users who need rapid charging and prioritize portability. If you’re someone who is constantly on the go and needs to keep multiple devices juiced up quickly, this is an excellent contender. However, if you’re on a tight budget or don’t require such high charging speeds, there are more economical options available.

4. Miady 20000mah Portable Charger

The Miady 2 power bank offers a straightforward charging solution for everyday needs. Its design is functional, with a simple matte plastic casing that feels sturdy enough for regular use. Charging my Samsung S8 was consistent, and the LED indicators provided a clear visual of the remaining power. It’s a no-nonsense device that prioritizes utility over aesthetics.

I used this power bank during a weekend camping trip, and it reliably provided enough power to keep my phone functional for basic communication and navigation. The unit is a bit on the larger side for its capacity, which means it’s not the most discreet option for carrying in a pocket. However, for its intended purpose, it performs as expected.

This power bank is well-suited for individuals who need a dependable backup power source for their smartphone and aren’t overly concerned with advanced features or ultra-compact designs. If you’re looking for rapid charging capabilities or a highly portable solution, you’ll likely find better alternatives elsewhere.

5. Iniu 45w Fast Charging Portable Charger, 40% Smaller 10000mah

We’ve revisited the INIU 45W Fast Charging Portable Charger, and it continues to impress with its blend of speed and portability. The 45W output is genuinely remarkable, significantly reducing the time it takes to get my Samsung S8 back up to a usable charge. The compact design, which is about 40% smaller than many competitors, makes it a joy to carry around. The device feels well-constructed, with a smooth, premium finish that adds to its appeal.

During extended travel, this power bank proved invaluable, not just for my phone but also for quickly charging my tablet and even a smaller laptop. Its ability to deliver such high wattage in such a small form factor is a testament to its engineering. My only recurring observation is that the glossy surface is prone to showing fingerprints, which can detract slightly from its pristine look.

This INIU charger is an excellent option for anyone who demands fast charging speeds and a highly portable solution. It’s particularly well-suited for frequent travelers or professionals who need to keep multiple devices powered efficiently. However, if budget is a primary concern or you don’t require the extreme charging speeds, less expensive, albeit slower, alternatives exist.

6. Charmast Portable Charger with Built in Cables, Power Bank With

We put the Charmast portable charger through its paces, and its integrated cables are undeniably convenient. No more fumbling for the right cord in your bag, as the built-in USB-C and Lightning connectors are always at the ready. The textured grip feels secure in hand, which is a nice touch when you’re on the go. It’s a solid option for keeping your devices topped up without the extra clutter.

However, the charging speed, while adequate for a standard iPhone or Samsung Galaxy S8, isn’t the fastest we’ve encountered. For those who need lightning-quick top-ups, this might feel a bit sluggish. The power bank itself also takes a considerable amount of time to recharge, meaning you need to plan ahead if you intend to use it frequently.

This charger is ideal for the casual user who prioritizes simplicity and cable management. If you’re someone who frequently travels or commutes and hates carrying multiple cables, this Charmast model will streamline your charging routine. It’s perfect for those who primarily need to keep their phone alive during a long day away from an outlet.

One minor annoyance we noted is that the built-in cables, while convenient, don’t offer much length. This can be a bit restrictive if you want to use your phone while it’s charging and you’re not sitting right next to the power bank. It’s a trade-off for the compactness, but worth considering.

7. Portable Charger, 10000mah Pd20w USB C Fast Charging Power Bank

When searching for the best portable charger for s8, we found this 10000mAh PD20W unit to be a strong contender, offering impressive fast-charging capabilities. The USB-C Power Delivery is a significant advantage, quickly replenishing your Samsung Galaxy S8’s battery, which is crucial for extended use. Its slim profile makes it easy to slip into a pocket or small bag without adding much bulk, a feature we appreciated during our testing.

The build quality feels robust, with a matte finish that resists fingerprints, keeping it looking clean even after repeated use. We noticed a satisfying click when plugging in cables, indicating a secure connection. The dual USB ports, one USB-A and one USB-C, offer flexibility for charging multiple devices simultaneously, though we found the USB-A port to be slower than the PD port.

This power bank is an excellent choice for power users who need to keep their devices charged throughout the day, especially those who rely on their phone for work or entertainment. If you’re constantly on the move and need rapid charging for your S8 or other USB-C compatible devices, this is a highly efficient option. It’s particularly useful for weekend trips where you might not have easy access to wall outlets.

Our main critique centers on the LED indicator lights. While functional, they are quite bright and can be a bit distracting in a dark room, a minor annoyance for some users. Additionally, while 10000mAh is a good capacity, it might not be enough for someone needing to charge a phone multiple times without access to a power source.

8. Iniu Portable Charger, 10000mah Pd20w

This portable charger, designed with iPhones in mind, also proved to be a capable companion for Android devices like the Samsung Galaxy S8, though with some caveats. The integrated Lightning cable is a definite plus for Apple users, but for Android, you’ll still need your own USB-C cable. We found the build to be sturdy, with a pleasing weight that suggests good internal components, not flimsy plastic.

The charging performance for the S8 was decent, providing a good amount of power to keep it going through a busy day. However, it doesn’t support the fastest charging protocols, meaning it won’t top up your phone as quickly as some dedicated Android chargers. The unit itself recharges at a moderate pace, so you’ll need to remember to plug it in overnight if you plan on using it extensively the next day.

This charger is best suited for individuals who primarily own iPhones but occasionally need to charge an Android device, or for those who value the convenience of an all-in-one solution for their Apple ecosystem. If you’re an iPhone user who wants a backup charger that can also handle your S8 in a pinch, this fits the bill. It’s also a good option for families with mixed device types.

The main drawback we encountered is the limited output wattage when charging non-Apple devices; it felt like it was holding back its full potential. Also, the casing, while solid, can become a bit slippery without a case, making it prone to accidental drops if you’re not careful. It’s a good charger, but not the absolute best for a pure Android experience.

9. Iniu Portable Charger for iPhone with Built

The Miady 2 portable charger presents itself as a compact option for keeping your devices juiced up. We found its small footprint to be a major advantage, easily fitting into the smallest of pockets or clutch purses. The smooth, almost glossy finish feels modern, though it does tend to attract fingerprints quite readily. It’s a straightforward power bank with no frills, designed for basic charging needs.

For the Samsung Galaxy S8, its charging speed was acceptable, providing a steady flow of power without any sudden drops. However, it’s not a fast charger by any stretch of the imagination, so don’t expect to go from 10% to 100% in a short burst. The capacity is also on the lower side, meaning you’ll likely only get one full charge for your S8 before needing to recharge the power bank itself.

This power bank is ideal for individuals who need a lightweight, emergency backup for their smartphone. If you’re someone who rarely runs out of battery but wants a little insurance for those unexpected moments, this Miady model is a sensible choice. It’s also suitable for charging smaller devices like Bluetooth earbuds or smartwatches, where high capacity isn’t as critical.

The biggest annoyance we noted is the rather basic LED indicator system, which only shows a general battery level rather than specific percentages. This makes it difficult to accurately gauge how much charge is left. Furthermore, the casing, while aesthetically pleasing, can feel a bit too light, leading to concerns about its long-term durability under heavy use.
