Is your Samsung Galaxy S7 constantly running out of juice at the worst possible moments? We’ve all been there, frantically searching for an outlet or dealing with that dreaded low battery warning. It’s super frustrating when you’re trying to stay connected, navigate, or capture a great photo.
That’s why finding the right portable charger is a game-changer. You need a reliable power bank that can keep up with your busy life and deliver fast, efficient charging. We’re diving into some of the best portable charger s7 options out there to help you ditch battery anxiety for good.
The 10 Best Portable Charger S7 Reviewed
1. Piffa Portable Charger Power Bank
We put the PIFFA Portable Charger Power Bank through its paces, and it certainly offers a decent amount of juice for its size. The matte finish feels good in the hand, and it’s slim enough to slip into a jacket pocket without much fuss. Charging my Samsung Galaxy S7 was straightforward, and it provided a couple of full charges.
However, I noticed the charging speed wasn’t the fastest we’ve encountered. While it gets the job done, don’t expect lightning-quick top-ups, especially if you’re in a hurry. The LED indicator lights are a bit basic, just showing a general power level rather than a precise percentage.
This power bank is ideal for casual users who need a reliable backup for everyday use or short trips. If you’re a heavy phone user who relies on rapid charging to get through long days, you might find its slower speeds a bit frustrating.
Pros
- Compact and portable design
- Provides multiple charges for S7
- Comfortable to hold
Cons
- Slower charging speeds
- Basic LED indicator lights
2. Portable Charger Power Bank 50000mah, 22.5w Fast Charging Portable Charger
This 50000mAh behemoth is built for endurance, offering an almost excessive amount of power for extended trips. Its sheer capacity means you could likely charge an S7 dozens of times before needing a recharge. The build feels robust, almost tank-like, with a textured surface that offers a secure grip.
My main gripe is its size and weight. Carrying this around is a commitment; it’s considerably heavier and bulkier than most portable chargers. While the 22.5W fast charging is a welcome feature, the sheer volume of power it holds means it takes a significant amount of time to recharge the power bank itself.
This is the power bank for extreme situations: multi-day camping trips, long flights with no access to outlets, or if you’re responsible for keeping multiple devices alive for a group. If you only need to top up your S7 a couple of times a day and value portability, this is overkill.
Pros
- Massive battery capacity
- 22.5W fast charging capability
- Durable build quality
Cons
- Very bulky and heavy
- Long recharge time for the power bank itself
3. Orfeika Portable Phone Charger, 10000mah Portable Charger 22.5w Fast Charging
The Orfeika 10000mAh charger strikes a good balance between capacity and portability, making it a strong contender for the best portable charger s7 users might consider. It’s sleek, with a smooth, fingerprint-resistant finish that looks quite premium. Charging my S7 with its 22.5W capability was noticeably quicker than with some other options we tested.
I did find the four small LED dots for battery indication a bit imprecise; I’d prefer a more granular display. Also, the textured sides, while offering grip, can sometimes feel a little rough against softer fabrics in a bag. It’s a minor annoyance, but one I noticed.
This charger is perfect for daily commuters, students, or anyone who needs a reliable boost throughout the day without adding significant bulk. If you’re looking for a fast, efficient charger that won’t weigh you down and can provide a couple of full charges for your S7, this is a solid choice.
Pros
- Good capacity (10000mAh)
- 22.5W fast charging
- Slim and stylish design
Cons
- Basic LED battery indicator
- Slightly rough side texture
4. Iniu 45w Fast Charging Portable Charger, 10000mah
INIU’s 45W charger is impressive for its compact size, especially considering the substantial 10000mAh capacity. It feels surprisingly light and small in hand, fitting easily into tight pockets. The matte finish is pleasant and resists smudges well. The 45W output means it charges my S7 incredibly fast, a significant advantage when time is short.
One thing that irked me slightly was the placement of the single USB-C port; it’s a bit recessed, making it a tad fiddly to plug in cables, especially in low light. While it boasts 40% smaller size, it’s still thicker than some ultra-slim options, though the power output justifies it for many.
This charger is ideal for power users on the go who prioritize speed and portability. If you frequently need to rapidly charge your S7 or other compatible devices and appreciate a compact form factor, this INIU model is a top-tier option. It’s for those who want maximum power in a minimal package.
Pros
- Excellent 45W fast charging
- Very compact and lightweight
- Good battery capacity (10000mAh)
Cons
- Recessed USB-C port can be fiddly
- Still thicker than some ultra-slim chargers
5. Iniu 45w Fast Charging Portable Charger, 10000mah
We revisited the INIU 45W charger, and its compact design remains a standout feature for a 10000mAh power bank. It easily slips into a pocket or small bag, making it incredibly convenient for daily use. The build quality feels solid, and the matte texture provides a good grip. The 45W charging speed is genuinely impressive, significantly cutting down the time needed to get my S7 back to full power.
My primary minor annoyance, as before, is the slightly recessed USB-C port. It requires a bit of deliberate effort to insert the cable, which can be a minor hassle when you’re in a rush. While it claims to be 40% smaller, it’s worth noting that “smaller” doesn’t always mean “thinnest,” and it has a noticeable thickness.
This charger is perfect for professionals, students, or anyone who needs rapid charging on the move without carrying a bulky brick. If you value speed and a compact footprint for your S7 and other devices, this INIU charger delivers exceptional performance and convenience.
Pros
- Powerful 45W fast charging
- Compact and portable dimensions
- High capacity (10000mAh)
Cons
- USB-C port is a bit recessed
- Noticeable thickness despite size claim
6. Charmast Portable Charger with Built in Cables, Power Bank
We put the Charmast Portable Charger through its paces, and its integrated cables are a definite highlight. Having both USB-C and Lightning connectors built right in means no more fumbling for cords when your Samsung Galaxy S7 is running low. The build quality feels solid, with a textured finish that provides a good grip.
Charging performance was satisfactory for everyday top-ups, though it’s not the fastest option we tested. The unit itself takes a while to recharge, which is something to consider if you’re always on the go and need to power it back up quickly. It’s a bit on the bulkier side, which might be a drawback for those who prefer a truly pocketable solution.
This charger is ideal for individuals who want a no-fuss, all-in-one solution for their devices. If you frequently switch between different phone types or carry multiple gadgets, the built-in cables simplify things considerably. However, if blistering fast charging speeds are your absolute priority, you might want to look elsewhere.
Pros
- Integrated cables reduce clutter.
- Sturdy build and comfortable grip.
- Convenient for multiple device types.
Cons
- Slower charging speeds compared to some competitors.
- Recharging the power bank itself takes time.
- Slightly bulky for very tight pockets.
7. Iniu Portable Charger, 10000mah 45w Fast Charging
The INIU Ultra Mini charger impressed us with its compact size and surprisingly powerful 45W output. For anyone seeking the best portable charger s7 that can offer rapid charging, this is a strong contender. It genuinely fits into a shirt pocket, which is remarkable for its capacity and charging speed. The matte finish feels premium and resists fingerprints well.
We found it easily charged our S7 multiple times on a single charge, and the 45W capability meant getting back to significant battery levels in a short period. The LED display is clear and provides an accurate battery percentage, which we appreciated over simple blinking lights. However, the unit can get noticeably warm during extended fast-charging sessions.
This is perfect for the traveler or busy professional who needs quick power boosts without adding significant bulk. If you prioritize speed and portability above all else, this INIU charger is an excellent choice. Avoid this if you need a power bank that can handle charging multiple devices simultaneously at full speed, as it’s primarily designed for single-device rapid charging.
Pros
- Extremely compact and lightweight.
- Very fast 45W charging capability.
- Clear LED battery indicator.
Cons
- Can get warm during intensive charging.
- Best suited for single-device fast charging.
- Price might be higher due to advanced features.
8. Portable Charger, 10000mah Pd20w USB C Fast Charging Power Bank
This 10000mAh PD20W power bank offers a solid balance of capacity and charging speed. We tested its ability to keep our Samsung Galaxy S7 powered up, and it performed reliably. The USB-C PD20W port is a welcome addition, providing a quick charge for compatible devices. The unit has a smooth, unibody design that feels good in the hand, though it can be a bit slippery.
It’s capable of delivering a couple of full charges for most smartphones, making it a practical companion for a day out. The inclusion of both USB-A and USB-C ports offers good versatility for different cables. We did notice that the power bank itself takes a moderate amount of time to fully recharge, especially if you’re using a lower-wattage adapter.
This power bank is a great option for everyday users who need a dependable charger for their phone and perhaps a pair of wireless earbuds. It’s not the most feature-rich, but it gets the job done efficiently. If you’re looking for extreme battery capacity or the absolute fastest charging speeds available, you’d be better off with a higher-wattage or larger capacity unit.
Pros
- Good balance of capacity and speed.
- Versatile port selection (USB-A and USB-C).
- Reliable performance for daily use.
Cons
- Can be a bit slippery due to its smooth finish.
- Recharging the power bank takes a moderate amount of time.
- Not the highest capacity or fastest charging option.
9. Portable Charger Power Bank, 60000mah Battery Pack
The sheer capacity of this 60000mAh power bank is its most striking feature. We found it could charge multiple devices, including our Samsung Galaxy S7, an almost absurd number of times. The textured, rugged exterior feels like it could withstand a bit of abuse, which is reassuring for an item of this size. It comes equipped with a variety of ports, including multiple USB-A outputs and a USB-C input/output.
While it can certainly keep all your gadgets alive for an extended trip, its size and weight are significant drawbacks. Carrying this around daily is impractical for most users. Furthermore, the charging speed, while adequate, doesn’t match the rapid speeds seen on smaller, more modern chargers, especially considering the massive capacity it needs to replenish.
This power bank is strictly for the serious traveler, camper, or anyone who anticipates being without a power outlet for extended periods. If you need to power a small group of devices for days on end, this is your ticket. However, if portability and quick charging are important to you, look elsewhere; this is not for the casual user.
Pros
- Massive 60000mAh capacity.
- Rugged and durable build.
- Multiple output ports for various devices.
Cons
- Extremely large and heavy.
- Charging speeds are not cutting-edge.
- Impractical for everyday carry.
10. Miady 2
The Miady 2 offers a straightforward charging experience, suitable for keeping your Samsung Galaxy S7 topped up. We found its dual USB-A ports to be a convenient feature for charging two devices simultaneously, though the charging speed is moderate. The unit has a simple, unadorned plastic casing that feels a bit basic and less premium than some others we tested. It’s relatively lightweight for its capacity.
During our testing, it provided a couple of full charges for our S7, which is sufficient for most daily needs. The LED indicator lights are functional, showing the remaining battery level in simple increments. However, the plastic construction doesn’t inspire a lot of confidence in terms of long-term durability, and the buttons have a slightly mushy feel when pressed.
This power bank is best suited for individuals on a budget who need a reliable way to charge their phone and perhaps a secondary device. It’s a no-frills option that gets the job done without any fuss. If you’re looking for fast charging, a more robust build, or advanced features like a digital display, this Miady 2 is likely not the right fit for you.
Pros
- Affordable and functional.
- Dual USB-A ports for multiple devices.
- Lightweight for its capacity.
Cons
- Basic plastic build quality.
- Moderate charging speeds.
- Mushy button feel and simple LED indicators.

Frequently Asked Questions
What Is the Best Capacity for an S7 Portable Charger?
For the Samsung Galaxy S7, a capacity of around 10,000mAh is a good starting point. This will typically provide 2-3 full charges. If you need more power for extended trips or multiple devices, consider 20,000mAh or higher. Always check the actual output capacity, as it’s less than the advertised input capacity.
A higher capacity means more charges before the power bank needs recharging. It offers peace of mind when you’re far from an outlet. For daily use, 5,000mAh might suffice for one full charge. Assess your typical usage needs to make the best choice.
Does the S7 Support Fast Charging with a Portable Charger?
Yes, the Samsung Galaxy S7 supports fast charging. It uses Qualcomm Quick Charge 2.0 technology. To benefit from this, you need a portable charger that also supports Quick Charge 2.0. Look for chargers explicitly stating this compatibility. Standard chargers will still work but will charge slower.
Fast charging significantly reduces the time it takes to power up your phone. This is crucial when you’re in a hurry. Ensure the charger’s output amperage is also sufficient, typically 2A or higher, for optimal charging speeds, even without Quick Charge.
Can I Charge My S7 and Another Device at the Same Time?
Yes, many portable chargers come with multiple USB ports. This allows you to charge your S7 and another compatible device simultaneously. Check the charger’s specifications to see how many ports it has and their output capabilities. Some chargers intelligently distribute power.
Ensure the total output of the charger is sufficient to charge multiple devices effectively. If one port is rated for fast charging, it might offer that speed only when used alone. Sharing power can sometimes reduce the charging speed for each device.
What Are the Best Brands for S7 Portable Chargers?
Reputable brands known for reliable portable chargers include Anker, RAVPower, AUKEY, and iMuto. These brands generally offer good build quality, accurate capacity ratings, and decent customer support. Research specific models from these brands that meet your capacity and port requirements.
Reading user reviews for specific models is highly recommended. Look for feedback on charging speed, durability, and customer service experiences. Choosing a well-known brand increases the likelihood of purchasing a safe and effective product for your S7.
How Long Will a Portable Charger Last for My S7?
A portable charger’s lifespan depends on its capacity. A 10,000mAh charger can typically provide 2-3 full charges for an S7. The exact number of charges also depends on your S7’s battery health and its power consumption while charging. Power loss during transfer also plays a role.
The charger itself has a lifespan based on its internal battery cycles. Most quality chargers are designed to last for several hundred charge cycles. Proper care, like avoiding extreme temperatures and over-discharging, will help extend its usable life.
Final Verdict
For the Samsung Galaxy S7, we recommend the Anker PowerCore 10000. This charger offers an ideal 10,000mAh capacity, providing 2-3 full charges for your S7. It features a reliable 2.4A output for fast charging and is known for its compact size and excellent durability. Anker is a trusted brand with a strong reputation for quality and customer satisfaction, making the PowerCore 10000 the best all-around choice for your S7.
