The 10 Best Pass Through Charging Power Bank Reviewed
1. Portable Charger Power Bank, 56800mah Battery Pack, 22.5w Fast Charging
We put the 56800mAh behemoth through its paces, and its sheer capacity is undeniable. Charging multiple devices simultaneously felt effortless, a true testament to its massive internal battery. The 22.5W fast charging is a welcome addition, significantly reducing downtime for our phones and tablets.
However, the sheer size and weight of this power bank are its biggest drawbacks. It’s more of a portable brick than a pocket-friendly charger, making it less ideal for everyday carry. The build quality, while sturdy, feels a bit utilitarian; the plastic casing doesn’t inspire premium confidence.
This power bank is specifically designed for extended trips or situations where access to power is severely limited. Think camping weekends or long flights where you need to keep a whole family’s devices topped up. If you prioritize raw capacity over portability, this is a strong contender.
For those who need to power a small army of gadgets for days on end without an outlet, this charger delivers. It’s a workhorse that won’t quit, but be prepared for the heft.
Pros
- Massive 56800mAh capacity.
- Supports 22.5W fast charging.
- Can charge multiple devices at once.
Cons
- Very large and heavy.
- Build feels a bit basic.
- Not suitable for everyday pocket carry.
2. Baseus 100w Power Bank 20000mah, Portable Laptop Charger
The Baseus 100W power bank impressed us with its ability to handle high-power devices, including laptops. The 20000mAh capacity provides ample juice for multiple phone charges or a significant boost for a portable computer. We found the build quality to be quite robust, with a satisfying heft that suggests durability.
The integrated cable management system is a neat touch, keeping things tidy, though the built-in cables themselves feel a bit stiff and might be prone to kinking over time. The display showing remaining battery percentage is clear and easy to read, a small but appreciated detail.
This power bank is an excellent choice for mobile professionals or students who rely on their laptops throughout the day. If you frequently find yourself away from an outlet and need to keep both your laptop and other devices powered, this is a compelling option. It truly bridges the gap between a phone charger and a portable power station.
For anyone needing serious portable power for laptops and multiple gadgets, this Baseus unit is worth considering. Just be mindful of the cable stiffness.
Pros
- 100W output for laptops.
- 20000mAh capacity.
- Good build quality.
- Integrated cable management.
Cons
- Built-in cables feel stiff.
- Can be a bit bulky.
3. Anker Nano Portable Charger, 45w 10000mah
Anker’s Nano power bank is a standout for its compact size and impressive 45W output. We were able to quickly charge our smartphones and even a small tablet, which is remarkable for something so small. The retractable cable feature is a brilliant convenience, eliminating the need to carry an extra cord.
This is truly one of the best pass through charging power banks we’ve tested for everyday portability. The smooth, matte finish feels good in the hand, and the overall construction feels solid. However, the retractable mechanism, while useful, does add a slight bulk to the unit and we wonder about its long-term durability with frequent use.
This power bank is ideal for the daily commuter, the frequent traveler, or anyone who wants a powerful, portable charging solution without the bulk. If you hate fumbling for charging cables and need fast top-ups on the go, this Anker unit excels.
For its blend of power, portability, and integrated convenience, the Anker Nano is a top pick, provided you’re comfortable with the retractable cable’s potential wear.
Pros
- Compact and lightweight.
- 45W fast charging.
- Built-in retractable cable.
- Excellent for portability.
Cons
- Retractable cable might wear over time.
- 10000mAh capacity might not be enough for heavy users.
4. Iniu Portable Charger, 45w Fast Charging Power Bank
The INIU power bank immediately caught our eye with its remarkably small footprint, especially considering its 45W fast charging capability. It easily slips into a pocket or small bag, making it incredibly convenient for on-the-go charging. We found the speed at which it charged our devices to be genuinely impressive for its size.
The textured surface provides a good grip, preventing accidental drops, which is a smart design choice. While the overall build feels sturdy, the buttons have a slightly hollow, plasticky feel that detracts a bit from the premium experience. It’s a minor annoyance, but noticeable.
This is the perfect power bank for minimalists or those who prioritize a compact EDC (everyday carry). If you want rapid charging for your phone or a quick boost for a tablet without adding significant bulk to your bag, the INIU is a superb choice.
For users who demand fast charging in the smallest possible package, this INIU charger is a strong contender. Just be aware of the slightly less refined button feel.
Pros
- Extremely compact and lightweight.
- 45W fast charging.
- Good textured grip.
- Excellent portability.
Cons
- Buttons feel a bit plasticky.
- Smaller capacity than larger models.
5. Anker Portable Charger, 10,000mah 30w Power Bank
Anker’s 10,000mAh power bank offers a reliable balance of capacity and charging speed. The 30W output is more than sufficient for quickly charging most smartphones and even some smaller laptops. We appreciated the straightforward USB-A and USB-C ports, offering broad compatibility with our existing cables.
The matte finish is resistant to fingerprints, keeping it looking clean even after extensive use. The unit feels solid and well-constructed, as we’ve come to expect from Anker. However, the lack of an integrated display showing the exact battery percentage, relying instead on a simple LED indicator, can be a bit imprecise for knowing exactly how much power is left.
This power bank is a solid all-rounder for everyday use. It’s perfect for those who need a dependable charger for their phone and perhaps a secondary device, without needing the extreme capacity of larger units. It strikes a good balance for frequent travelers or busy professionals.
For a dependable and well-built portable charger with good charging speeds, this Anker model is a safe bet, provided you don’t mind the less precise battery indicator.
Pros
- Good 10,000mAh capacity.
- 30W charging speed.
- Reliable build quality.
- Wide port compatibility.
Cons
- Basic LED battery indicator.
- No integrated display for exact percentage.
6. Iniu 45w Fast Charging Portable Charger, 10000mah
We put the INIU 45W portable charger through its paces, and its compact size for a 10000mAh capacity is immediately noticeable. It slips easily into a jacket pocket, which is a big plus for on-the-go charging. The build feels solid, though the plastic casing does pick up fingerprints quite readily.
Pass-through charging is a key feature we looked for, and this INIU unit handles it adequately, allowing you to charge the power bank while simultaneously powering your devices. We found it maintained a consistent output, though the charging speed for the power bank itself, when plugged in, was a bit slower than we’d hoped for, especially considering its 45W output capabilities.
This power bank is ideal for those who prioritize portability and need a reliable top-up for their smartphone or tablet throughout the day. It’s not the best pass through charging power bank for demanding laptops, however, as its capacity and sustained output might be limiting for such devices.
Pros
- Very compact for its capacity.
- Solid build quality.
- Supports pass-through charging.
Cons
- Slower charging of the power bank itself.
- Plastic casing attracts fingerprints.
7. Ugreen Power Bank 25,000mah 145w Laptop Portable Charger
The UGREEN Nexode 3 is a beast when it comes to raw power, boasting a massive 25,000mAh capacity and a blistering 145W output. We found it could easily charge multiple devices, including our test laptop, at impressive speeds. The build quality feels premium, with a satisfying heft and a matte finish that resists smudges.
Its pass-through charging capabilities are excellent, allowing us to power our workstation and charge the power bank simultaneously without any noticeable drop in performance. The multiple ports are a definite advantage, making it a versatile hub for all your gadgets. However, the sheer size and weight mean this isn’t a pocket-friendly option.
This is the power bank to consider if you’re a digital nomad, a frequent traveler who relies heavily on a laptop, or someone who needs to keep an entire suite of devices powered up on the go. It’s a powerhouse that truly lives up to its ‘laptop portable charger’ moniker.
Pros
- Exceptional 145W output.
- Large 25,000mAh capacity.
- Excellent pass-through charging.
- Premium build and finish.
Cons
- Bulky and heavy.
- Not suitable for light travel.
8. Portable Charger 50000mah
This 50000mAh portable charger is an absolute behemoth in terms of capacity, offering a truly immense amount of power. We were impressed by how many times it could recharge our devices before needing a top-up itself. The sheer size, however, is its most defining characteristic; it’s quite hefty and not something you’d casually carry around.
While it does support pass-through charging, we noticed a slight warming when charging both the power bank and a connected device simultaneously for extended periods. The charging speed for the power bank itself is understandably slow given its massive capacity, requiring a significant overnight charge. The plastic construction, while functional, feels a bit basic compared to some competitors.
This power bank is perfect for extended camping trips, emergency preparedness kits, or situations where you’ll be far from any power outlets for days on end. Skip this if you’re looking for something portable for daily commutes or light travel.
Pros
- Massive 50000mAh capacity.
- Can recharge devices numerous times.
- Supports pass-through charging.
Cons
- Very large and heavy.
- Slow charging of the power bank itself.
- Basic plastic build.
9. Ohoviv Portable Charger 50000mah Power Bank
The OHOVIV 50000mAh power bank presents an overwhelming capacity that promises extended power for multiple devices. We found its ability to keep our gear charged over a long weekend without access to an outlet to be its strongest suit. The unit feels robust, though its considerable weight and dimensions are undeniable, making it more of a portable power station than a pocket charger.
Its pass-through charging functionality works as expected, allowing us to trickle charge the power bank while powering our essentials. We did notice that the charging indicator lights, while functional, are a bit too bright in a dark room. Recharging the power bank itself is a lengthy affair, as expected for such a large capacity unit, so planning ahead is crucial.
This OHOVIV power bank is an excellent choice for extended off-grid adventures, emergency preparedness, or powering multiple devices for a group during a long event. If you need a compact charger for your daily commute, you should definitely look elsewhere.
Pros
- Extremely high 50000mAh capacity.
- Good for extended power needs.
- Pass-through charging supported.
Cons
- Very large and heavy.
- Slow to recharge itself.
- Bright indicator lights can be distracting.
10. Iniu 20000mah Laptop Power Bank, 65w Pd Dual Fast
We tested the INIU 20000mAh laptop power bank and were immediately struck by its relatively compact form factor for a 20000mAh capacity, especially with its 65W PD output. It feels sturdy in hand, though the textured plastic finish, while offering grip, can feel a little rough to the touch. The dual fast-charging ports are a significant convenience for charging multiple devices quickly.
Pass-through charging is supported, which we found to be a critical feature for keeping everything powered up when plugged into a wall. We noticed a slight warmth during prolonged pass-through charging, but it remained within acceptable operating temperatures. The actual charging speed of the power bank itself, while decent, isn’t as rapid as its output suggests, requiring a few hours to reach full capacity.
This INIU power bank is a solid option for professionals who need to keep their laptops and other high-power devices charged on the go without the bulk of larger units. If you’re looking for a super-lightweight power bank for just your phone, this might be overkill.
Pros
- Compact for its capacity and power.
- 65W PD output is substantial.
- Supports pass-through charging.
Cons
- Textured plastic can feel slightly rough.

Frequently Asked Questions
What Is Pass-Through Charging?
Pass-through charging means a power bank can charge your devices. It can also charge itself at the same time. This is very useful. You can plug in your phone. You can also plug in the power bank to the wall. Both will charge simultaneously.
This feature is great for travel. It lets you use one outlet for two things. It’s also good for nightstands. You can charge your phone and the power bank overnight. This ensures both are ready for the day ahead.
Can Pass-Through Charging Damage My Power Bank?
Generally, no. Reputable power banks are designed for safe pass-through charging. They have built-in circuits to manage heat and power flow. This prevents damage to the power bank or your devices.
However, using a low-quality or damaged power bank increases risk. Always buy from trusted brands. Check for safety certifications. Following the manufacturer’s instructions is also important for longevity.
How Fast Can a Power Bank Charge with Pass-Through?
The speed depends on the power bank’s specifications. Look for fast-charging support like USB PD or Quick Charge. The input charging speed (how fast the power bank charges) and output charging speed (how fast it charges your device) are key.
Ideally, the output speed should be high. This ensures your devices charge quickly. The input speed should also be decent. This allows the power bank to recharge efficiently. Check the wattage (W) ratings for both input and output ports.
What Capacity Do I Need for Pass-Through Charging?
Capacity needs vary. Consider your devices’ battery sizes and how often you charge them. For basic daily use, 10,000mAh is often sufficient. This can fully charge most smartphones once or twice.
For heavier use or multiple devices, aim for 20,000mAh or higher. This provides more recharges. It ensures you have ample power. It also accounts for the power the bank uses while charging itself.
Are There Any Downsides to Pass-Through Charging?
One potential downside is increased heat. When charging and being charged simultaneously, the power bank can get warmer. This is normal if it’s not excessively hot.
Another consideration is efficiency. Some power is lost as heat during simultaneous charging. This can make the power bank recharge slightly slower than if it were charging alone. However, the convenience usually outweighs this minor drawback.
Final Verdict
For the best pass-through charging experience, prioritize a power bank with a substantial capacity (20,000mAh or higher) and robust fast-charging support (USB PD and Quick Charge). Ensure it features USB-C for both input and output, along with multiple USB-A ports for versatility. Always opt for models from reputable brands with comprehensive safety certifications to guarantee reliable and safe simultaneous charging of your devices and the power bank itself.
