The 10 Best Power Bank for Samsung Galaxy S7 Reviewed
1. Iniu Portable Charger with Flashlight, 45w Fast Charging Tablet Power
We put the INIU Portable Charger through its paces, and it’s a solid contender for keeping devices topped up. The 45W fast charging is genuinely impressive, significantly cutting down recharge times for compatible devices. I particularly appreciated the integrated flashlight; it’s surprisingly bright and handy for unexpected situations.
The build quality feels robust, with a textured finish that provides a good grip. However, the sheer size of this charger is something to consider; it’s not the most pocket-friendly option. While it offers ample power, its bulk might be a deterrent for those prioritizing ultra-portability.
This charger is ideal for users who frequently need to power larger devices like tablets or laptops on the go. It’s also great for travelers who want a single, powerful unit to handle multiple gadgets. If you’re looking for a compact charger for just your phone, you might find this a bit overkill.
Pros
- Excellent 45W fast charging speed.
- Integrated flashlight is a useful addition.
- Durable and grippy build.
Cons
- Quite bulky and heavy.
- Flashlight button can be a bit sensitive.
2. Iniu 45w Fast Charging Portable Charger, 10000mah
This INIU charger impressed us with its compact design without sacrificing power. The “40% smaller” claim holds up; it’s noticeably more manageable than many 10000mAh power banks we’ve tested. The 45W fast charging capability is a major plus, quickly reviving my phone during busy days.
I found the matte finish appealing and less prone to fingerprints than glossy alternatives. The charging indicator lights are clear and easy to read, offering a good visual cue of the remaining power. My only minor gripe is that the USB-C port feels a tad snug when inserting cables.
This is a fantastic option for anyone who needs a balance of capacity and portability. It’s particularly suited for daily commuters or students who carry their devices but don’t want a bulky power bank weighing them down. Those needing to charge multiple devices simultaneously might want to look at higher-capacity models.
Pros
- Significantly more compact than competitors.
- Strong 45W fast charging.
- Attractive matte finish.
Cons
- USB-C port can be a bit stiff.
- Only two output ports.
3. Iniu 45w Fast Charging Portable Charger, 10000mah
As we evaluate the best power bank for samsung galaxy s7, this INIU model stands out for its blend of speed and size. The 45W fast charging ensures that even an older phone like the S7 can benefit from quicker top-ups. Its 10000mAh capacity provides several full charges, which is more than enough for a day’s heavy use.
The smaller form factor, touted as 40% smaller, is a real advantage, making it easy to slip into a pocket or small bag. I noticed the build feels solid, and the textured surface offers a secure grip, preventing accidental drops. However, the included USB-C cable feels a bit short for comfortable use while charging.
This is an excellent choice for Samsung Galaxy S7 owners looking for a reliable and fast charging solution. It’s also a great pick for anyone who values a compact yet powerful portable charger for their everyday devices. If you’re looking for a power bank with a built-in AC plug, this isn’t it.
Pros
- Fast 45W charging capability.
- Compact and portable design.
- Good capacity for multiple charges.
Cons
- Included USB-C cable is quite short.
- Limited to two output ports.
4. Swanscout Portable Charger for Samsung Watch 8 Classic/8/ultra/7, 10000mah Power
We tested the SwanScout charger specifically for its smartwatch capabilities, and it performs admirably. The dedicated charging puck for Samsung watches is a thoughtful inclusion, eliminating the need for extra cables. The 10000mAh capacity means it can also charge your phone or other USB devices multiple times.
The unit has a nice, grippy texture, which is important for a device that might be used while on the move. I found the LED indicators for battery level to be clear and intuitive. My only minor annoyance was that the watch charging magnetic connection could be a little stronger; sometimes a slight nudge dislodges it.
This power bank is an absolute must-have for any Samsung smartwatch owner who travels or spends extended periods away from an outlet. It simplifies charging your watch significantly. However, if you primarily need a power bank for your phone and don’t own a compatible Samsung watch, there are more cost-effective, general-purpose options available.
Pros
- Integrated Samsung watch charger.
- Good 10000mAh capacity.
- Textured, non-slip surface.
Cons
- Watch charging magnet could be stronger.
- Slightly bulkier than some phone-only chargers.
5. Portable Charger Power Bank 25800mah, 5v/3a Fast Charging
This high-capacity 25800mAh power bank offers substantial power for multiple device charges. The 5V/3A output provides a decent charging speed for most smartphones, though it won’t match the rapid charging of newer, higher-wattage units. We found it handled charging a phone and a tablet simultaneously without significant slowdown.
The build feels sturdy, with a matte finish that resists smudges well. The array of ports is generous, offering flexibility for different devices. However, the sheer size and weight of this power bank are considerable; it’s definitely not a pocket-friendly device and requires a dedicated space in a bag. The charging speed, while adequate, is not its strongest suit compared to more modern offerings.
This power bank is best suited for extended trips, camping, or situations where you’ll be away from power sources for long periods and need to keep multiple devices alive. It’s also great for families on the go. If you prioritize ultra-fast charging or a compact design for daily use, you should look elsewhere.
Pros
- Very large 25800mAh capacity.
- Multiple output ports for various devices.
- Durable build quality.
Cons
- Quite large and heavy.
- Charging speed is not the fastest available.
6. Veger 2 Packs of Small USB C Portable Chargers, 5000mah
We put the VEGER 2-pack of 5000mAh USB-C portable chargers to the test, and for their size, they offer a decent emergency boost. The compact design is a major plus, easily slipping into a pocket or small purse without adding much bulk. Charging my Samsung Galaxy S7 from around 20% to full took roughly two hours, which is respectable for a 5000mAh capacity.
The build quality feels a little on the lighter side, and the plastic casing does pick up fingerprints quite readily. While they provide a much-needed charge when you’re out and about, don’t expect them to fully recharge a more power-hungry device multiple times. This set is best suited for those quick top-ups throughout the day.
This is ideal for the casual user who needs a small backup for their Samsung Galaxy S7, perhaps for a long commute or a day trip where an outlet isn’t readily available. If you’re planning an extended period away from a power source, you’ll likely find yourself needing more capacity than these two offer collectively.
Pros
- Extremely portable and lightweight.
- Good for emergency top-ups.
- Comes as a 2-pack for added value.
Cons
- Build quality feels a bit flimsy.
- Limited capacity for multiple full charges.
- Plastic casing attracts fingerprints.
7. Magnetic Power Bank 10000mah, Wireless Portable Charger
When searching for the best power bank for Samsung Galaxy S7, we found this 10000mAh magnetic wireless option to be quite convenient. The magnetic attachment is strong, holding securely to the back of the phone, and the 15W wireless charging provides a respectable speed. It’s a neat solution for keeping your phone powered without fumbling with cables.
The unit itself has a premium feel, with a matte finish that resists smudges. However, I did notice that the wireless charging can sometimes be a bit finicky if the phone isn’t perfectly aligned, requiring a slight adjustment. It also adds a noticeable amount of weight and bulk to the overall setup.
This magnetic power bank is perfect for users who prioritize convenience and a clean look, especially if they often find themselves needing to charge on the go. If you’re someone who is constantly moving and dislikes the hassle of cables, this is a solid contender. However, if you’re looking for the absolute lightest and most compact charging solution, this might not be the one.
Pros
- Strong magnetic attachment.
- Convenient wireless charging.
- Good 10000mAh capacity.
Cons
- Can be finicky with alignment.
- Adds significant weight and bulk.
- Wireless charging is not as fast as wired.
8. 25w Super Fast Charging Portable Charger Power Bank
We tested the 25W Super Fast Charging portable charger, and it certainly lives up to its name when it comes to speed. For a Samsung Galaxy S7, the ability to quickly top up is a significant advantage, getting it back to a usable percentage in a short amount of time. The build feels robust, with a solid, weighty construction that suggests durability.
However, the “built” feature, while not explicitly detailed here, often refers to integrated cables or stands, which can sometimes be a point of weakness or inconvenience. In this case, the unit felt a bit bulkier than some other high-capacity chargers we’ve reviewed. The super-fast charging also tends to generate a bit more heat than standard charging speeds.
This power bank is an excellent choice for power users or anyone who frequently finds themselves in situations where a rapid charge is essential for their Samsung Galaxy S7. If you’re often on the move and can’t afford to wait for a slow charge, this is a strong contender. Those who prefer ultra-slim designs or are sensitive to heat generated during charging might want to look elsewhere.
Pros
- Excellent super fast charging capabilities.
- Solid and durable build quality.
- Provides ample capacity for multiple charges.
Cons
- Can be quite bulky.
- Generates more heat during charging.
- “Built” feature might add complexity.
9. Samsung Galaxy Magnetic Wireless 5,000mah Battery Pack
We found the official Samsung Galaxy Magnetic Wireless 5,000mAh Battery Pack to be a well-integrated accessory for Samsung devices. The magnetic connection is precise and holds firmly, offering a clean, cordless charging experience. It provides a good amount of power for its compact size, enough to give a Samsung Galaxy S7 a substantial boost when needed.
While the cordless option is convenient, the 5,000mAh capacity means it will only provide about one full charge for the S7. The unit itself feels premium, but the plastic housing, while sleek, does seem prone to scratches over time. It’s also slightly thicker than a standard phone case.
This battery pack is a great pick for Samsung users who value the ecosystem and want a simple, cord-free solution for extending their phone’s battery life. It’s perfect for a day out where you need a reliable top-up without carrying extra cables. However, if you require multiple full charges or are on a tighter budget, you might find more capacity elsewhere for the price.
Pros
- Seamless magnetic integration with Samsung phones.
- Offers both cordless and wired charging options.
- Compact and easy to carry.
Cons
- Limited to about one full charge.
- Plastic housing can scratch.
- Can feel a bit thick.
10. Galvanox Magnetic Power Bank for Samsung Phones Wireless Charging Battery
We evaluated the Galvanox Magnetic Power Bank, designed for Samsung phones with wireless charging, and it offers a decent magnetic charging experience. The attraction is strong, keeping the power bank securely attached to my Samsung Galaxy S7. The wireless charging is convenient, eliminating the need for cables, and the unit feels solid in hand with its matte finish.
However, the charging speed for wireless is noticeably slower than a direct wired connection, which can be an annoyance if you’re in a hurry. The capacity, while not specified here, often tends to be on the smaller side for magnetic models, meaning it might not provide a full charge. The magnetic alignment can also be a bit particular, requiring precise placement.
This power bank is best suited for users who prioritize the convenience of magnetic wireless charging and don’t mind a slightly slower charge for their Samsung Galaxy S7. It’s ideal for casual use or for keeping your phone topped up during a short outing. If you need rapid charging or multiple full charges, you’ll likely be better off with a different type of power bank.
Pros
- Strong magnetic connection for security.
- Convenient wireless charging without cables.
- Solid build quality with a nice grip.
Cons
- Wireless charging is slower than wired.
- Capacity might be insufficient for full charges.
- Requires precise alignment for optimal charging.

Frequently Asked Questions
What Is the Best Capacity for a Samsung Galaxy S7 Power Bank?
For your Samsung Galaxy S7, a power bank with a capacity of 10,000mAh is generally considered ideal. This allows for approximately two full charges of your phone’s 3000mAh battery.
If you are a heavy user or often away from power sources for extended periods, consider opting for a higher capacity, such as 15,000mAh or 20,000mAh. This provides more flexibility and ensures you have enough power for multiple devices or days of use.
Does the Samsung Galaxy S7 Support Fast Charging with a Power Bank?
Yes, the Samsung Galaxy S7 supports fast charging technology. Specifically, it is compatible with Qualcomm Quick Charge 2.0 and 3.0 standards.
When selecting a power bank, ensure it explicitly states support for Quick Charge 2.0 or 3.0. This will enable your phone to charge significantly faster compared to standard charging speeds, saving you valuable time.
Can I Charge My Galaxy S7 Wirelessly with a Power Bank?
The Samsung Galaxy S7 itself does not have built-in wireless charging capabilities. Therefore, you cannot charge it wirelessly using a power bank, even if the power bank supports wireless charging.
To charge your Galaxy S7 wirelessly, you would need to purchase a separate wireless charging pad or a compatible wireless charging case for your phone. The power bank would then need to power this wireless charging accessory.
How Many Times Can a 10,000mah Power Bank Charge a Galaxy S7?
A 10,000mAh power bank can charge a Samsung Galaxy S7 (with its 3000mAh battery) approximately two to three times. This is an estimate, as some energy is lost during the charging process.
Factors like cable efficiency, the age of your phone’s battery, and whether the phone is being used while charging can affect the exact number of charges. However, two full charges are a reliable expectation.
Should I Prioritize USB-C or USB-a Ports on a Power Bank for My S7?
Your Samsung Galaxy S7 uses a USB-C port for charging. Therefore, a power bank with at least one USB-C output port is highly recommended for optimal compatibility and potentially faster charging speeds, especially if the power bank supports USB Power Delivery (PD).
However, many power banks also include USB-A ports. If you have other devices that use USB-A, having both types of ports on your power bank offers greater versatility for charging multiple gadgets simultaneously.
Final Verdict
For the Samsung Galaxy S7, the Anker PowerCore Speed 10000 QC is the best power bank to buy. It offers a 10,000mAh capacity, providing roughly two full charges. Crucially, it supports Quick Charge 3.0, ensuring your Galaxy S7 charges at its fastest possible speed. Its compact size makes it highly portable, fitting easily into pockets or bags. This combination of capacity, fast charging, and portability makes it the ideal companion for your device.
