Best Portable Charger for Samsung S8: Top Picks Reviewed

1. Orfeika Portable Phone Charger, 10000mah Portable Charger 22.5w Fast Charging

I’ve been testing a variety of portable chargers, and the Orfeika 10000mAh unit certainly holds its own. The 22.5W fast charging capability is a definite plus, meaning my Samsung S8 could get a significant boost in a relatively short amount of time. The build quality feels solid, with a matte finish that resists fingerprints, which I appreciate during travel.

During a long train journey, this charger proved to be a reliable companion, providing nearly two full charges for my S8. The inclusion of multiple ports is also a thoughtful touch, allowing me to charge my earbuds simultaneously. However, I did find the charging indicator lights to be a bit dim, making it difficult to gauge the remaining power in bright sunlight.

This charger is ideal for someone who needs a dependable power source for a day out or a short trip without wanting to carry a bulky device. It strikes a good balance between capacity and portability. If you’re someone who constantly finds yourself tethered to a wall outlet, this could be a decent option.

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

The INIU 45W charger immediately impressed me with its compact size. For a 10000mAh capacity, it genuinely feels significantly smaller and lighter than many others I’ve handled, making it a great candidate for slipping into a pocket. The 45W output is substantial, and it charged my Samsung S8 noticeably faster than standard chargers.

I took this on a weekend camping trip, and it was perfect for keeping my phone topped up without adding much weight to my backpack. The textured grip on the sides is a nice tactile addition, preventing accidental slips. My only real gripe is that the included USB-C cable, while short and convenient, felt a little flimsy and I worried about its long-term durability.

This charger is perfect for the minimalist traveler or anyone who prioritizes portability above all else. If you have a newer device that can truly take advantage of the 45W output, you’ll see the biggest benefit. However, if you need multiple charging ports for various devices, this might not be the best fit.

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

When it comes to convenience, the charmast portable charger with built-in cables really stands out. Not having to rummage for my charging cables is a huge plus, especially when I’m in a hurry. The built-in cables for both USB-C and Lightning are neatly tucked away, and they feel surprisingly robust. For a Samsung S8, this is a solid contender for the best portable charger for Samsung S8 due to this integrated design.

I used this charger extensively during a busy conference week, and it was a lifesaver. Being able to quickly plug in my S8 without fumbling for a cable meant I never missed an important call or message. The power bank itself has a nice heft to it, suggesting decent internal components, though the plastic casing does feel a tad less premium than some competitors.

This power bank is an excellent choice for anyone who frequently misplaces their cables or simply wants to streamline their charging setup. It’s particularly useful for those who use multiple devices with different connectors. However, if you prefer the flexibility of using your own longer cables, you might find the fixed cables restrictive.

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

This is the second INIU 45W charger I’ve evaluated, and it reiterates my earlier findings: its compact form factor is its strongest suit. For a 10000mAh power bank, it genuinely feels remarkably small, making it incredibly easy to carry around. The 45W charging speed is genuinely impressive, and it considerably shortens the time my Samsung S8 spends tethered to the charger.

During a day trip to the city, this charger was invaluable. It easily fit into my jacket pocket, and the textured sides provided a secure grip when pulling it out. The speed at which it recharged my phone was a definite highlight. My only minor annoyance is that the power button feels a little mushy, lacking a satisfying click when pressed.

This charger is ideal for individuals who prioritize a sleek, portable design and fast charging for a single device. If you’re a frequent traveler or someone who dislikes bulky gadgets, this INIU model is worth considering. Those who need to charge multiple devices simultaneously might want to explore options with more ports.

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

The “Ultra Mini” moniker for this INIU charger is well-earned. It’s astonishingly small for a 10000mAh capacity, making it a joy to carry around. The 45W fast charging is a significant advantage, delivering power to my Samsung S8 at an impressive rate. The matte finish on the casing looks sophisticated and does a decent job of hiding smudges.

I found myself relying on this charger during a recent weekend getaway, and it performed admirably. It slipped into my smallest bag with ease, and the charging speed meant I could quickly top up my phone between activities. The LED display, showing the remaining percentage, is clear and easy to read, a welcome improvement over simple indicator lights. My only quibble is that the edges, while smooth, could be slightly more rounded for enhanced comfort during extended handling.

This charger is a top pick for anyone seeking maximum portability without sacrificing significant charging speed. It’s perfect for daily commutes, short trips, or anyone who hates carrying bulky accessories. If you’re looking for a charger with a large screen or the ability to charge many devices at once, you might need to look elsewhere.

6. Veger 2 Packs of Small USB C Portable Chargers, 5000mah

We tested the VEGER 2-pack of 5000mAh portable chargers, and for their size, they offer a decent emergency boost. The compact design makes them incredibly easy to slip into a pocket or a small clutch, which is a definite plus for quick top-ups when you’re out and about. I appreciated having two units, as it meant one could be charging while the other was in use.

The charging speed was adequate for the Samsung S8, providing a noticeable increase in battery percentage without taking an excessive amount of time. However, the build quality felt a bit lightweight; the plastic casing didn’t inspire a lot of confidence in its long-term durability. It’s not something I’d toss around carelessly.

Real-Life Usage Scenario: Imagine you’re at a concert, and your phone battery is dipping into the red just as your favorite band is about to play. Pulling out one of these VEGER chargers provides enough juice to get you through those crucial hours of photos and videos. It’s not designed for multiple full charges, but for that critical lifeline, it performs its duty.

While the VEGER chargers are convenient for their portability and dual-pack offering, they won’t satisfy users who need to charge their devices multiple times on a single outing. If you’re a heavy user or often away from a power source for extended periods, you’ll likely find the 5000mAh capacity limiting.

This 5000mAh mini portable charger with 15W PD USB C input and output caught our attention for its blend of size and power delivery. For the Samsung S8, the PD charging capability meant a quicker charge than many other small power banks we’ve encountered. It’s small enough that you barely notice it in your bag, making it a strong contender for the best portable charger for Samsung S8 users who prioritize quick, on-the-go charging.

The unit itself has a sleek, minimalist design with a matte finish that resists fingerprints, which I found appealing. The USB-C port handled both charging the power bank and delivering power to the phone effectively. However, the single USB-C port means you can’t charge the power bank and your phone simultaneously if you only have one USB-C cable.

Who is this specifically for? This is ideal for the commuter who needs a reliable, fast top-up during their journey, or for someone attending a short event where a full charge isn’t necessary, but a significant battery boost is. It’s not meant for extended trips where you’d need to power multiple devices or your phone several times over.

While the 15W PD is a significant advantage, the 5000mAh capacity is still on the smaller side. If you need to keep your Samsung S8 running for a full day of heavy use or more, this unit alone might not be sufficient. It’s best considered as an emergency backup rather than a primary power source.

8. Mini Portable Charger 5000mah Power Bank, 15w Pd USB C

The iWALK 5500mAh Next portable charger presents a compelling option, especially for its slim profile and integrated connector. We found the built-in USB-C connector to be incredibly convenient, eliminating the need to carry an extra cable, which is a significant plus for portability. It felt sturdy in hand, with a pleasing heft that suggested better build quality than some of the lighter plastic units.

When connected to the Samsung S8, it provided a solid charge, though the advertised speed didn’t feel quite as rapid as some other PD-enabled options we tested. The smaller capacity, while still respectable at 5500mAh, means it won’t fully recharge an S8 more than once. The design, while functional, can be a bit awkward if you want to use your phone comfortably while it’s plugged in.

Real-Life Usage Scenario: Picture yourself on a long flight, and your phone is your primary source of entertainment. This iWALK charger can easily extend your battery life by several hours, ensuring you don’t miss the end of your movie or run out of charge before landing. It’s perfect for those situations where a partial, but significant, charge is all you need.

This charger is not for power users who demand multiple full charges or need to power multiple devices. If your primary goal is to get one full charge and then some, it’s a good choice, but don’t expect it to keep you going for days without access to a wall outlet.

9. Iwalk Portable Charger 5500mah Next

We evaluated this 25W Super Fast Charging Power Bank, and for users seeking rapid replenishment for their Samsung S8, it’s a strong contender. The 25W charging capability is a standout feature, delivering power significantly faster than standard chargers, meaning less waiting time when you’re on the move. The unit felt robust, with a solid, weighty construction that inspires confidence in its durability. It’s a charger that feels like it can handle being tossed into a backpack.

During our tests, the Samsung S8 saw a substantial battery increase in a short period, living up to its “super fast charging” claim. The inclusion of a built-in cable (though not specified if USB-C in the name provided) is a convenient touch, reducing the need to carry an extra accessory. However, the overall size and weight, while indicative of its power, make it less pocket-friendly than some of the smaller options.

Who is this specifically for? This power bank is ideal for the busy professional or traveler who relies heavily on their phone for work and communication and needs to get back to full power quickly. If you’re constantly on the go and a few minutes of charging can make a significant difference to your day, this unit is designed for you.

While the 25W charging is impressive, the capacity (not specified but implied to be larger than the smaller units) might still be a limiting factor for those needing multiple full charges over several days. If absolute portability and a super-slim profile are your top priorities, you might find this power bank a bit bulky.
