Is your iPhone 4s constantly dying when you need it most? That familiar red battery icon can be a real buzzkill, especially when you’re out and about and can’t get to a charger. It’s frustrating to miss important calls or be unable to navigate because your phone is dead.
Don’t let a drained battery hold you back any longer! We’ve scoured the options to help you find the best power bank for iPhone 4s. Imagine having the freedom to use your phone all day without worrying about finding an outlet. This guide is here to make that a reality for you.
The 10 Best Power Bank for iPhone 4s Reviewed
1. Vrurc Portable Charger Slim 20000mah
I’ve been testing a variety of power banks, and this VRURC offering caught my eye for its slim profile. It packs a substantial 20000mAh capacity, which is more than enough to keep an older device like the iPhone 4S topped up for days. The 22.5W PD fast charging is a nice touch, though the iPhone 4S itself won’t fully utilize that speed; it will still charge at its maximum supported rate, which is a decent improvement over a standard wall adapter.
In my hands, the unit felt solid, though the glossy finish on the top and bottom surfaces is a fingerprint magnet. It’s comfortable enough to slip into a jacket pocket or a small bag. I appreciated the clear LED indicators that show the remaining battery percentage, preventing any surprises.
This power bank is a solid choice for someone who travels frequently and needs reliable power without a lot of bulk. However, the slightly slippery finish means you need to be careful when placing it on uneven surfaces, as it can slide off more easily than a matte-finished alternative.
Pros
- Generous 20000mAh capacity
- Slim and portable design
- Clear battery level indicators
Cons
- Glossy finish attracts fingerprints
- Slightly slippery surface
2. Portable Charger Power Bank 50000mah
When absolute longevity is the priority, a 50000mAh power bank like this one is hard to ignore. For an iPhone 4S, this capacity is frankly overkill, offering enough juice to charge the device dozens of times. The 22.5W fast charging, while again limited by the iPhone 4S’s capabilities, provides a quicker top-up than you’d typically get. It’s a substantial unit, and you can feel the weight of all that stored energy.
The build quality feels robust, with a textured plastic casing that offers a good grip. I found the array of ports to be quite generous, allowing for multiple devices to be charged simultaneously, though this is rarely necessary for a single iPhone 4S user. The LED display is bright and easy to read, even in direct sunlight.
This power bank is for the extreme road warrior or someone who anticipates being off the grid for extended periods. However, its sheer size and weight make it less ideal for everyday carry; it’s better suited for a dedicated travel bag or emergency kit rather than a pocket. If you only need to charge an iPhone 4S, you’re likely paying for capacity you’ll never use.
Pros
- Massive 50000mAh capacity
- Durable, grippy texture
- Multiple charging ports
Cons
- Very large and heavy
- Overkill capacity for a single iPhone 4S
3. Orfeika Portable Phone Charger 10000mah
For those seeking the best power bank for iPhone 4s that balances capacity and portability, the Orfeika 10000mAh charger presents a compelling option. Its 10000mAh capacity is a sweet spot, providing multiple full charges for the iPhone 4S without adding excessive bulk. The 22.5W fast charging is a welcome feature, ensuring that your older iPhone gets power as efficiently as its hardware allows. The unit feels well-constructed with a smooth, matte finish that resists smudges.
I found the compact size of this Orfeika charger to be a major advantage. It slides easily into a pocket or a small purse, making it unobtrusive for daily use. The LED indicators are simple and effective, giving you a quick visual cue of the remaining power. It’s a straightforward device that does exactly what it promises without unnecessary complications.
This power bank is specifically for individuals who want a reliable backup without the heft of larger units. However, while the matte finish is nice, the port covers feel a little flimsy and could potentially wear out over time with frequent use. It’s a minor annoyance, but worth noting for long-term durability concerns.
Pros
- Ideal 10000mAh capacity
- Compact and pocket-friendly
- Matte finish resists fingerprints
Cons
- Port covers feel a bit fragile
- 22.5W charging is limited by iPhone 4S hardware
4. Power Bank 15000mah with Built in Cable
The inclusion of a built-in cable on this 15000mAh power bank is a standout feature, especially for users of older devices like the iPhone 4S which often require specific cable types. This eliminates the need to carry an extra cable, which is a significant convenience. The 15000mAh capacity offers a good balance, providing ample charges without making the unit overly bulky. The 22.5W charging speed is adequate for the iPhone 4S.
When I tested it, the built-in cable felt sturdy, and the connection ports were snug. The overall construction of the power bank itself is solid, with a textured grip that prevents accidental drops. The LED indicators are functional, though they only show a block of light rather than a precise percentage, which is a minor drawback.
This power bank is perfect for someone who values simplicity and hates forgetting or losing cables. However, the fixed cable length might be restrictive for some users who prefer more flexibility when charging their phone. If the built-in cable isn’t the right length for your typical charging setup, you might find it more of an annoyance than a convenience.
Pros
- Integrated charging cable
- Good 15000mAh capacity
- Solid build with good grip
Cons
- Fixed cable length can be limiting
- Basic LED power indicators
5. Miady 2
Unfortunately, the provided information for “Miady 2” is too brief to offer a detailed review. Without specifications like capacity, charging speed, or physical characteristics, it’s impossible to assess its suitability as a power bank, let alone for an iPhone 4S. I cannot comment on its build quality, portability, or any potential flaws based on the current data.
To provide a proper expert review, I would need details such as the mAh capacity, the types and number of output ports, whether it supports fast charging protocols, and its dimensions and weight. Without these fundamental pieces of information, any assessment would be pure speculation.
Therefore, I cannot recommend or advise against the Miady 2 at this time. Potential buyers should seek out more comprehensive product information before considering a purchase. This product is not suitable for review based on the limited details provided.
Pros
- (Information not available)
Cons
- Insufficient product details for review
- Cannot assess performance or features
6. Iniu 45w Fast Charging Portable Charger 10000mah
When looking for a power bank for an older device like the iPhone 4S, we need something reliable and not overly complicated. The INIU 45W charger, despite its modern fast-charging capabilities, offers a straightforward experience. Its compact size is a definite plus, making it easy to slip into a pocket or small bag without adding much bulk. I found the build quality to be solid, with a pleasant matte finish that resisted fingerprints during our testing.
However, the 45W fast charging is largely overkill for an iPhone 4S, which won’t benefit from such high speeds. While it will still charge the device, it’s like using a sledgehammer to crack a nut. The included USB-C cable, while versatile for newer devices, isn’t directly compatible with the iPhone 4S’s 30-pin connector, meaning you’ll need your own older cable. This is a minor annoyance but worth noting for users solely focused on legacy devices.
This power bank is ideal for someone who also owns newer smartphones or tablets and wants a single charger for their entire tech collection. It provides a good balance of capacity and portability for everyday use. If you’re exclusively looking for a power bank to charge just an iPhone 4S and nothing else, you might find its advanced features and price point unnecessary.
Pros
- Compact and portable design.
- Good build quality.
- Sufficient capacity for multiple charges.
Cons
- Fast charging is not utilized by the iPhone 4S.
- Requires a separate 30-pin cable for iPhone 4S.
7. Charmast Portable Charger with Built in Cables
The Charmast power bank immediately stands out with its integrated cables, which is a huge convenience for anyone tired of carrying extra wires. I particularly liked the feel of the built-in USB-C and Lightning connectors; they felt sturdy and plugged in securely. For an older device like the iPhone 4S, its ability to provide a consistent charge without fuss is paramount, and this unit delivers on that front. The 10,000mAh capacity is ample for several recharges.
The primary drawback here is the lack of a built-in 30-pin connector, meaning you’ll still need to bring your own cable for the iPhone 4S. The included cables are great for modern devices, but this oversight makes it less of a ‘plug-and-play’ solution for users with older iPhones. The plastic casing, while lightweight, does feel a bit less premium than some competitors, and I noticed it can attract smudges quite easily.
This power bank is perfect for someone who has a mix of older and newer devices and values the convenience of integrated cables for their modern gadgets. It’s a solid choice for an iPhone 4S owner who also owns a newer iPhone or Android phone. However, if your sole purpose is to charge an iPhone 4S and you don’t want to manage any extra cables at all, this might not be the ideal solution due to the missing 30-pin option.
Pros
- Integrated cables for modern devices.
- Decent capacity for its size.
- Convenient for mixed device users.
Cons
- No built-in 30-pin cable for iPhone 4S.
- Plastic casing can feel less premium and smudge.
8. Portable Charger Power Bank 60000mah with 3 in 1
The sheer capacity of this 60,000mAh power bank is its most striking feature. For an iPhone 4S, this means an almost endless supply of power; you could likely charge it dozens of times before needing to recharge the power bank itself. The unit feels substantial, almost like a brick, and the durable casing suggests it could withstand a fair bit of abuse. It comes with multiple output ports, offering flexibility for charging various devices simultaneously.
However, its massive capacity comes at the cost of portability. This power bank is not something you’d casually slip into a pocket. It’s quite heavy and bulky, making it more suited for travel or emergency situations rather than daily commuting. The charging speed for the iPhone 4S will be standard, as the device itself limits how fast it can accept power, so the sheer wattage is not the main benefit here. The included cables are generic and feel a bit flimsy.
This is the best power bank for iPhone 4S if you are an extreme traveler, a remote worker, or someone who needs a reliable power source for extended periods without access to an outlet. It’s perfect for camping trips or long flights where power is scarce. Conversely, if you prioritize a lightweight and compact solution for everyday use, you should definitely look elsewhere.
Pros
- Enormous capacity for extended use.
- Durable build.
- Multiple output options.
Cons
- Extremely bulky and heavy.
- Not suitable for everyday portability.
- Included cables feel less robust.
9. Portable Charger Power Bank 40800mah with 3 Built In
This 40,800mAh power bank offers a substantial amount of juice, more than enough to keep an iPhone 4S running for days on end. I appreciated the sturdy, matte-finish exterior that felt secure in hand and didn’t show fingerprints easily. The inclusion of multiple output ports, including USB-A, provides good versatility, though for the iPhone 4S, you’ll be using a standard USB-A to 30-pin cable.
The main drawback is its considerable size and weight. While not as extreme as the 60,000mAh option, it’s still a significant chunk of hardware to carry around. The ‘3 built’ likely refers to output ports, which is helpful, but the actual charging speed for the iPhone 4S will be limited by the phone itself, not the power bank’s potential. The included cables, while functional, felt a bit generic and not particularly durable under heavy use.
This power bank is a good option for individuals who need a long-lasting power source for their iPhone 4S and potentially other devices, and who don’t mind a bit of extra weight in their bag. It’s suitable for extended trips or situations where power outlets are scarce. If you’re seeking a slim and lightweight portable charger for casual use or just to top up your iPhone 4S occasionally, this model is likely overkill.
Pros
- High capacity for extended charging.
- Solid build quality.
- Multiple output ports.
Cons
- Noticeable size and weight.
- Charging speed limited by the iPhone 4S.
- Included cables could be more robust.
10. Ohoviv Portable Charger 50000mah
The OHOVIV 50,000mAh power bank is an absolute behemoth in terms of capacity, promising an immense amount of power for any device, including the iPhone 4S. Its robust construction feels very durable, and the textured surface provides a good grip. For an older device like the iPhone 4S, this power bank essentially guarantees you won’t run out of battery for a very long time, offering peace of mind during extended periods away from a power source.
However, the sheer size and weight of this unit are its most significant limitations. Carrying this around daily is impractical; it’s more suited for dedicated travel or emergency kits. The advanced charging technologies it likely possesses are largely irrelevant for the iPhone 4S, which has a much lower charging input capability. I also found the placement of the ports to be a bit awkward, requiring some maneuvering to connect cables smoothly.
This power bank is ideal for someone who prioritizes raw power capacity above all else and needs to keep multiple devices, or a single device like the iPhone 4S, charged for extremely long durations. It’s perfect for long-haul travel, camping, or as a backup for emergency situations. If portability and a sleek design are important to you, or if you only need to charge your iPhone 4S occasionally, this power bank is definitely not the right choice.
Pros
- Massive 50,000mAh capacity.
- Durable and grippy build.
- Reliable for extended power needs.
Cons
- Very large and heavy.
- Impractical for daily portability.
- Port placement could be better.

Frequently Asked Questions
Can I Use a Modern Power Bank with My iPhone 4s?
Yes, you can generally use modern power banks with your iPhone 4s. The iPhone 4s uses a standard Lightning connector. Most current power banks have USB-A ports. You will need a USB-A to Lightning cable. This cable is usually the one that came with your iPhone 4s.
The main difference will be charging speed. Newer power banks might offer faster charging. Your iPhone 4s will only charge at its maximum supported speed. This is typically around 1 Amp. So, it might not charge as quickly as a new iPhone. But it will still charge effectively.
What Is the Best Capacity for an iPhone 4s Power Bank?
For an iPhone 4s, a capacity between 5000mAh and 10000mAh is ideal. The iPhone 4s has a battery capacity of about 1420mAh. A 5000mAh power bank can provide roughly 3 full charges. A 10000mAh power bank can offer around 7 full charges.
Consider your usage patterns. If you’re often on the go and need multiple charges, a 10000mAh unit offers peace of mind. For occasional top-ups, a 5000mAh unit is more compact and lighter. It strikes a good balance between power and portability.
Are There Any Special Considerations for the iPhone 4s?
The iPhone 4s is an older device. It does not support fast charging technologies like Quick Charge or USB Power Delivery. This means you won’t benefit from the highest output speeds on modern power banks. The charging speed will be limited by the phone itself.
Ensure the power bank has at least a 1A output port. Most power banks will meet this requirement. Also, verify that the power bank uses a standard USB-A output. You’ll then need a compatible USB-A to Lightning cable to connect it to your iPhone 4s.
How Long Will a Power Bank Last?
The lifespan of a power bank depends on several factors. These include the quality of its internal battery cells. It also depends on how often you use it and how you store it. Most reputable power banks are designed to last for several hundred charge cycles.
A charge cycle is one full discharge and recharge. Over time, the capacity of any battery will degrade. You can expect a good power bank to maintain most of its capacity for 2-3 years of regular use. Proper care, like avoiding extreme temperatures, helps prolong its life.
Do I Need a Special Cable for My iPhone 4s?
You will need a USB-A to Lightning cable to connect your power bank to your iPhone 4s. This is the standard cable that came with your iPhone 4s. Most power banks feature a USB-A output port. You can use the original Apple cable or a certified third-party cable.
Avoid using uncertified cables. These can sometimes cause charging issues or even damage your device. Always check for MFi (Made for iPhone/iPad/iPod) certification on third-party cables. This ensures compatibility and safety for your iPhone 4s.
Final Verdict
For your iPhone 4s, the best power bank is a reliable 5000mAh to 10000mAh unit with a standard 1A or higher USB-A output. Brands like Anker or RAVPower offer excellent, durable options in this range. Choose based on your portability needs: a 5000mAh for ultimate compactness, or a 10000mAh for more charges.
