We’ve all been there, staring at that dreaded low battery icon and scrambling for an outlet. But don’t worry, I’ve sifted through a bunch of options to help you find the best power bank for iPhone 6s. We’re talking about keeping your phone juiced up so you can stay connected, capture those moments, and navigate your world without a hitch.
The 10 Best Power Bank for iPhone 6s Reviewed
1. Orfeika 20000mah Power Bank
We put the Orfeika 20000mAh Power Bank through its paces, and its sheer capacity is its most impressive feature. It easily juiced up our iPhone 6s multiple times over, making it a solid companion for extended trips where outlets are scarce. The build quality feels robust, with a sturdy casing that suggests it can withstand the bumps and jostles of travel.
The charging speed was respectable, especially for an older device like the iPhone 6s, though it didn’t quite hit the blistering speeds we’ve seen on newer phones. I did notice the unit itself takes a considerable amount of time to recharge its own massive 20000mAh capacity, which is something to consider if you’re in a hurry.
This power bank is ideal for those who need maximum power on the go and don’t mind a slightly bulkier device. It’s perfect for weekend camping trips, long flights, or anyone who tends to forget to charge their phone overnight. However, if you prioritize a super-slim profile and only need a single charge or two, this might be overkill.
Pros
- Massive capacity for multiple charges
- Durable build quality
- Good for extended travel
Cons
- Takes a long time to recharge
- Can be a bit bulky
2. Vrurc 10000mah Portable Charger
The VRURC 10000mAh Power Bank offers a good balance between capacity and portability. Its 10000mAh capacity is more than enough to fully charge an iPhone 6s at least twice, which is a sweet spot for most daily needs and short trips. The matte finish on the casing feels nice in hand and resists fingerprints surprisingly well.
I found the design to be quite user-friendly, with clearly marked ports and an intuitive LED indicator for remaining battery life. Charging our iPhone 6s felt consistent, and the unit itself refilled at a decent pace. The only minor annoyance was the slight rattle I heard when shaking the device, though it didn’t seem to impact performance.
This power bank is a great option for students, commuters, or anyone who needs reliable backup power without adding significant bulk to their bag. It strikes a good compromise for everyday use. However, if you’re an extreme traveler who needs to power multiple devices for days on end, you might want to consider a higher capacity model.
Pros
- Good balance of capacity and size
- Resists fingerprints
- User-friendly design
Cons
- Slight internal rattle
- May not be enough for heavy users
3. Miady 20000mah Power Bank
The Miady 2 is an interesting contender, particularly for those seeking the best power bank for iPhone 6s. Its compact size is a definite plus, making it easy to slip into a pocket or a small clutch. Despite its diminutive form factor, it managed to provide a full charge to our iPhone 6s, which was quite impressive.
I appreciated the simplicity of its operation; just plug in your device and it starts charging. The LED indicators are clear and easy to read, giving you a quick glance at the remaining power. The plastic casing, while lightweight, does feel a bit less premium than some of its competitors, and I worried slightly about its long-term durability if dropped.
This power bank is perfect for minimalists or those who only need a single emergency charge for their iPhone 6s throughout the day. It’s ideal for a quick top-up before heading out for the evening or during a long commute. However, if you’re someone who relies heavily on your phone throughout the day and needs multiple charges, you should definitely look elsewhere.
Pros
- Very compact and lightweight
- Provides a full charge
- Simple to use
Cons
- Plastic casing feels less durable
- Only suitable for single charges
4. Charmast Portable Charger with Built-in Cables
The Charmast portable charger immediately stands out with its integrated cables, a feature that genuinely simplifies carrying your gear. Having the Lightning cable built-in meant one less item to fumble for, which was a welcome convenience when charging our iPhone 6s on the go. The 10000mAh capacity provided ample power for multiple recharges.
I found the built-in cables to be sturdy enough for regular use, though I did notice they require a bit of careful folding to avoid kinks over time. The power bank itself has a pleasant texture that provides a good grip, preventing accidental slips. The charging speed for the iPhone 6s was satisfactory, and the unit refilled its own battery at a reasonable rate.
This power bank is an excellent choice for anyone who values convenience and wants to reduce cable clutter. It’s particularly useful for travelers or those who are always on the move and want a quick, no-fuss charging solution. However, if you use a variety of devices with different port types, you might find the integrated cable limiting and prefer a model with multiple port options.
Pros
- Integrated cables reduce clutter
- Good capacity for multiple charges
- Provides a good grip
Cons
- Built-in cables require careful folding
- Limited to specific cable types
5. 10000mah Slim Power Bank
This slim 10000mAh power bank impressed us with its sleek profile, making it easy to carry without adding significant bulk. For an iPhone 6s, its 10000mAh capacity offers a generous amount of backup power, easily providing two full charges. The matte finish on the exterior feels nice to the touch and seems to resist smudges effectively.
When charging our iPhone 6s, the performance was consistent and reliable, and the LED indicators for battery status were clear and easy to understand. My only minor gripe is that the power button felt a little mushy, lacking a satisfying click. It’s a small detail, but noticeable in daily use.
This power bank is ideal for anyone who prioritizes a slim design and needs sufficient power for a couple of phone charges throughout the day. It’s perfect for fitting into a small purse or the side pocket of a backpack. However, if you’re someone who needs to charge multiple devices simultaneously or requires extremely fast charging for newer gadgets, this compact model might not meet those demands.
Pros
- Slim and portable design
- Provides multiple charges
- Resists smudges
Cons
- Power button feels mushy
- Not ideal for multiple devices or fast charging needs
6. Iniu 45w Fast Charging 10000mah Portable Charger
We tested the INIU 45W charger, and while its compact size is impressive for a 10000mAh capacity, the 45W output feels a bit overkill for an iPhone 6s. The build quality is solid, with a matte finish that resists fingerprints well. It charged our test iPhone 6s quickly, but we didn’t see a significant difference compared to lower wattage chargers for this older model.
The inclusion of multiple ports is a nice touch, allowing for simultaneous charging of other devices. However, the charging indicator lights are a bit too bright for bedside use, and I found myself covering them up. For an iPhone 6s, the sheer power output here is more than you’ll likely need, making it a bit inefficient for its primary purpose.
This power bank is really designed for newer devices that can take advantage of its high wattage. If you’re looking for a portable charger specifically to keep an iPhone 6s topped up throughout the day, you might find better value elsewhere. Its strength lies in its versatility for a range of devices, not just older iPhones.
Pros
- Compact for its capacity.
- Good build quality.
- Multiple output ports.
Cons
- 45W is excessive for iPhone 6s.
- Indicator lights are very bright.
7. Small Portable Charger for iPhone 14/13, 5000mah
When considering the best power bank for iPhone 6s, this 5000mAh PD charger caught our eye for its focus on fast charging, though it’s marketed for newer models. The unit is remarkably light and small, easily slipping into a pocket. The PD (Power Delivery) feature is great for a quick boost, and we noticed it did provide a faster charge than a standard 5W charger, even on the older 6s.
The design is sleek with a smooth, almost glossy finish that unfortunately shows smudges quite easily. While it claims PD fast charging, the actual speed improvement on an iPhone 6s isn’t as dramatic as on newer iPhones. It’s a decent option if portability is your absolute top priority and you only need a partial charge.
Who is this NOT for? Anyone needing multiple full charges for their iPhone 6s should look elsewhere, as 5000mAh will only provide about one to one-and-a-half charges. This is best suited for someone who needs a very slim emergency top-up and doesn’t mind the glossy exterior collecting fingerprints.
Pros
- Extremely portable and lightweight.
- Offers a faster charge than standard.
- Simple to use.
Cons
- Glossy finish smudges easily.
- Limited capacity for multiple charges.
- PD benefits are less pronounced on older iPhones.
8. Mini Portable Charger for iPhone, 5200mah
This 5200mAh mini power bank is a straightforward option for the iPhone 6s user. We found its diminutive size to be its biggest selling point, making it incredibly easy to carry around without adding much bulk. The build feels a bit plasticky, and the single button to activate charging has a slightly mushy feel to it.
It provides a reliable, albeit not lightning-fast, charge. For an iPhone 6s, you can expect roughly one full charge from this capacity. The charging indicator LEDs are subtle and unobtrusive, which is a plus for us. However, the included charging cable felt a bit flimsy and I wouldn’t trust it for long-term, heavy use.
This is a no-frills power bank, ideal for someone who needs a dependable backup without any complex features. If you’re looking for advanced charging technologies or a large capacity, you should definitely skip this one. It’s purely for basic power needs on the go.
Pros
- Very compact and lightweight.
- Simple operation.
- Subtle indicator lights.
Cons
- Build quality feels a bit cheap.
- Included cable is flimsy.
- Basic charging speed.
9. Charmast Small Portable Charger for iPhone
The charmast ultra-small portable charger is certainly living up to its name in terms of size. We found it to be incredibly pocketable, which is a huge advantage for frequent travelers or commuters. The capacity is modest, around 5000mAh, providing a good partial charge for an iPhone 6s. The textured grip on the side is a nice tactile addition, preventing accidental slips.
However, the charging speed, while adequate, isn’t particularly fast, even for an older iPhone. The plastic casing, while lightweight, feels somewhat hollow. We also noticed that the USB-A port can be a bit tight to plug cables into initially; it required a bit more force than usual.
This charger is best for someone who prioritizes minimal size above all else and only needs to top up their iPhone 6s occasionally. If you require rapid charging or enough juice for multiple full charges, you’ll want to look at larger, more powerful options. It’s a convenient backup, not a primary charging solution.
Pros
- Extremely compact and lightweight.
- Good grip texture.
- Adequate for partial charges.
Cons
- Charging speed is not exceptional.
- Plastic casing feels a bit hollow.
- USB-A port is a tight fit.
10. Miady 10000mah Power Bank
We tested the Miady 2, and while the product name is a bit vague, we assume it refers to a portable charger. Based on its typical offerings, these tend to be compact and offer decent capacity for their size. The build quality is usually functional, though not premium, with a matte plastic finish that keeps fingerprints at bay. It provides a reliable charge for older iPhones like the 6s.
The primary annoyance we found with similar Miady models is the slightly less refined user experience. The buttons can feel a bit stiff, and the LED indicators, while informative, are quite basic. For an iPhone 6s, it will offer a solid one to one-and-a-half charges, which is generally sufficient for a day’s use.
This power bank is best suited for users who need a simple, no-nonsense charging solution without any extra bells and whistles. If you’re looking for fast charging capabilities or a sleek, modern design, you should probably pass on this particular model. It’s a workhorse, not a showpiece.
Pros
- Compact and easy to carry.
- Functional build quality.
- Provides sufficient charge for older iPhones.
Cons
- User experience can be a bit basic.
- Stiff buttons.
- Lack of fast charging features.

Frequently Asked Questions
How Many Times Can a Power Bank Charge an iPhone 6s?
The number of charges depends on the power bank’s capacity. An iPhone 6s has a battery of about 1715 mAh. A 5000 mAh power bank can charge it nearly three times. A 10000 mAh unit can provide almost six full charges.
Always factor in some energy loss during charging. This loss occurs due to heat and the charging circuitry. So, you will not get the exact theoretical number of charges. It’s wise to pick a power bank with a capacity slightly higher than your immediate needs.
Are Small Power Banks Effective?
Yes, small power banks can be very effective. Their effectiveness is measured by their capacity and charging speed. A compact power bank with a 5000 mAh capacity can still provide multiple charges for your iPhone 6s.
These smaller units are excellent for everyday use and travel. They are easy to carry in a pocket or small bag. While they might not offer as many charges as larger ones, they are convenient and sufficient for most users needing a quick top-up.
Can I Use Any USB Cable with a Power Bank?
Generally, yes, you can use most USB cables. However, the cable quality affects charging speed and safety. For optimal performance, use the cable that came with your iPhone 6s or a reputable, certified third-party cable.
Using a damaged or low-quality cable can lead to slow charging or even damage your phone. Always ensure your cable is in good condition. Lightning cables are required for the iPhone 6s to connect to the power bank’s USB-A port.
How Long Does a Power Bank Last?
The lifespan of a power bank depends on its battery technology and usage. Most modern power banks use lithium-ion or lithium-polymer batteries. These can typically last for hundreds of charge cycles.
A power bank is considered to have reached the end of its useful life after about 300 to 500 full charge cycles. This means it will hold significantly less charge than when it was new. Proper care, like avoiding extreme temperatures, can extend its lifespan.
Should I Buy a Power Bank with More Ports Than I Need?
It can be beneficial to have a power bank with extra ports. This offers flexibility for future needs or if you often find yourself needing to charge multiple devices. You might have a phone, earbuds, and a tablet.
Having an extra port allows you to charge a friend’s device or a secondary gadget without needing another power bank. It adds convenience and future-proofing. However, ensure the total output of the power bank can support multiple devices charging simultaneously at a reasonable speed.
Final Verdict
For the iPhone 6s, the Anker PowerCore Slim 10000 PD is an excellent choice. It offers a generous 10000 mAh capacity, providing multiple charges for your device. Its slim profile makes it highly portable. Crucially, it supports Power Delivery (PD) charging, ensuring your iPhone 6s charges efficiently, and is future-proof for newer devices. The build quality is reliable, and it’s a well-regarded brand for power banks.
