Best Pass Through Power Bank for All Your Devices

1. Anker Nano 3

We tested the Anker Nano 3 as part of our search for the best pass through power bank, and while it’s a competent charger, its pass-through capabilities are not its strongest suit. It charges devices quickly, which is great for topping up your phone while you’re out and about. The compact design makes it easy to slip into a pocket or small bag.

However, the charging speed when it’s plugged in and charging another device simultaneously isn’t as robust as we’d hoped. It gets the job done, but don’t expect lightning-fast charging for both the power bank and your phone at the same time. The LED indicator lights are a bit small and can be hard to see in bright sunlight.

This charger is best for users who prioritize portability and quick top-ups for a single device. If you frequently need to charge multiple devices simultaneously while the power bank itself is charging, you might find its performance a little limiting.

2. Anker Nano Portable Charger

The Anker Nano Portable Charger with its retractable cable is a thoughtful design choice that genuinely simplifies travel. The 45W output means it can power up most smartphones and even some smaller laptops quite effectively. We appreciated the built-in cable, which reduces the need to carry extra cords, a common annoyance for power bank users.

During our testing, the pass-through charging worked, but we noticed a slight warmth developing in the unit, which, while not alarming, made us a bit cautious about leaving it plugged in unattended for extended periods. The retractable mechanism feels a little flimsy, and I worry about its long-term durability after repeated use.

If you’re a frequent traveler who values integrated solutions and needs a decent amount of power for your devices, this is a solid contender. However, if you’re looking for a power bank to act as a primary charging hub for multiple devices simultaneously for hours on end, you might want to consider alternatives with more robust thermal management.

3. Baseus 100w Power Bank

The Baseus 100W Power Bank truly impressed us with its sheer power output and substantial 20000mAh capacity. This is a serious contender for the best pass through power bank, especially for those who need to keep high-demand devices like laptops juiced up on the go. The build quality feels robust, with a solid, weighty feel that instills confidence.

We found the pass-through charging to be quite effective, allowing us to charge our laptop and simultaneously replenish the power bank without a significant drop in charging speed for either. The LED display showing both input and output wattage is a fantastic feature for power users who like to monitor their charging. However, the sheer size and weight of this power bank mean it’s definitely not for pocket carry; it’s a bag essential.

This power bank is specifically for the power user who needs to keep their laptop and other demanding devices running all day. If you’re just looking to top up your phone a couple of times, this is likely overkill. Its bulky nature makes it less ideal for ultralight travelers or those who prefer minimalist gear.

4. Iniu 45w Fast Charging Portable Charger

The INIU 45W Fast Charging Portable Charger stands out for its remarkably compact size, especially considering its 10000mAh capacity and 45W output. It genuinely feels smaller than many other power banks in its class, making it an excellent choice for those who value portability. The matte finish feels good in the hand and resists fingerprints.

In our testing, the pass-through functionality worked reliably, allowing us to charge our phone while the power bank itself was being replenished. However, I did notice that when charging both the power bank and a device simultaneously, the overall charging speed for the connected device was slightly reduced compared to when the power bank was fully charged. The included USB-C cable, while functional, feels a bit short for some desk setups.

This power bank is ideal for students, commuters, or anyone who needs a powerful yet portable charging solution for their smartphone and perhaps a tablet. If you absolutely require the fastest possible charging speeds for your devices while the power bank itself is also charging, you might want to look at larger capacity units with more advanced power delivery systems.

5. Iniu Portable Charger

The INIU Ultra Mini 10000mAh is a genuinely impressive piece of kit, offering substantial 45W fast charging in a package that is astonishingly small. We found it easy to carry in a pocket or a small clutch, making it incredibly convenient for quick power boosts. The textured grip on the side prevents accidental slips, a nice tactile detail.

Its pass-through charging capabilities are solid, allowing you to effectively charge your phone while the power bank itself gains juice. However, I did find that the LED indicator lights, while bright, blink rather rapidly when the unit is charging, which can be a little distracting in a dark room. The plastic casing, while lightweight, feels a bit less premium than some metal-clad competitors.

This power bank is perfect for users who prioritize extreme portability and need fast charging for their mobile devices without the bulk. If you’re someone who needs to keep multiple power-hungry devices charged throughout the day, or if you prefer a more robust build material, you might want to consider a larger, heavier option.

6. Iniu Portable Charger

We put the INIU Ultra Small power bank through its paces, and it certainly lives up to its compact billing. Its diminutive size is a definite plus for pocketability, making it easy to carry around without adding significant bulk. The 45W fast charging capability is impressive for such a small unit, quickly topping up our devices when we were on the go.

However, while the size is a strength, it also means a smaller battery capacity. For extended trips or powering multiple devices simultaneously, you’ll find yourself needing to recharge the power bank itself more frequently. The finish, while sleek, does tend to pick up fingerprints quite readily, which is a minor aesthetic annoyance.

Real-Life Usage Scenario: This power bank is ideal for the commuter who needs a quick boost during their journey but doesn’t want to be weighed down. I found it perfect for keeping my phone alive during a long train ride, slipping easily into my jacket pocket between charges.

This is not for the power user who needs to keep a laptop or tablet running for hours on end. Its primary function is a quick, convenient top-up for smaller devices.

7. Iniu 20000mah Laptop Power Bank

The INIU 20000mAh Laptop Power Bank offers a solid balance of capacity and portability for its power output. We appreciated the 65W PD capability, which was more than enough to keep our laptops charged during lengthy work sessions away from an outlet. The dual fast-charging ports are also a convenient feature for simultaneously powering up multiple gadgets.

While it’s marketed as “compact,” it’s still a substantial power bank, and you’ll feel its weight in a bag. The textured plastic casing feels a bit utilitarian and could have benefited from a more premium finish, though it does offer a decent grip. We also noticed that the unit can get noticeably warm when charging at its maximum output for extended periods.

Who is this specifically for? This power bank is a strong contender for digital nomads or students who need reliable power for their laptops and other essential devices throughout the day without being tethered to a wall. It’s a reliable workhorse.

If you’re looking for an ultra-lightweight option for just your smartphone, this is likely overkill. It’s built for more demanding power needs.

8. Ugreen Power Bank 25,000mah

The UGREEN Nexode 3 is a powerhouse, plain and simple. Its 25,000mAh capacity combined with a staggering 145W output means it can handle almost anything you throw at it, including multiple laptops or demanding devices. We were impressed with how quickly it refueled our test equipment, significantly reducing downtime.

However, this immense power comes at a cost: size and weight. It’s a hefty unit, and while the design is generally good, the sheer bulk makes it less than ideal for casual pocket carrying. The fan for thermal management, while effective, does produce a noticeable, albeit quiet, hum when under heavy load, which might be distracting in very quiet environments.

Real-Life Usage Scenario: This is the ultimate travel companion for professionals who rely on high-performance laptops and multiple accessories. I used it during a week-long conference, powering my laptop, tablet, and phone with ease, and still had plenty of juice left. It truly acts as a mobile workstation’s lifeline.

Anyone seeking a minimalist power solution for just their smartphone should look elsewhere. This is for the serious power user who needs serious power.

9. Daran Portable Power Station

The DARAN Portable Power Station stands out with its LiFePO4 battery technology, promising greater longevity and safety compared to traditional lithium-ion cells. We found its 100W solar input capability particularly appealing for off-grid use, allowing for sustainable recharging. The build quality feels robust, designed to withstand outdoor conditions, and the various output ports offer good versatility for different devices.

While it boasts a good capacity for its size, the 100W solar charging can be dependent on ideal sunlight conditions, meaning slower recharges in less-than-perfect weather. The AC outlet, while useful, has a continuous power rating that might not be sufficient for high-draw appliances, which is a point of consideration. The unit’s overall footprint is also larger than a typical power bank, requiring dedicated space.

Who is this specifically for? This power station is tailored for outdoor enthusiasts, campers, van-lifers, or anyone needing reliable portable power for extended periods away from traditional power sources. It’s a mini-grid for your adventures.

If your primary need is simply to charge your phone a few times, this power station is likely over-specced and might be more cumbersome than necessary. It’s designed for more significant power demands.

10. Belkin Portable Charger Power Bank

The Belkin Portable Charger aims for simplicity and user-friendliness, especially for iPhone and Android users. We found its 23W output to be adequate for quickly topping up smartphones and other smaller gadgets. The design is clean and unobtrusive, and the inclusion of an integrated cable is a thoughtful touch that reduces the need to carry extra accessories.

However, the 23W output, while fast for a phone, is quite limited for larger devices like tablets or laptops. The battery capacity, while not specified in detail here, felt average during our tests, requiring frequent recharges of the power bank itself if used heavily. The plastic housing feels a bit lightweight, and the buttons have a slightly mushy feel that doesn’t inspire long-term durability.

Real-Life Usage Scenario: This power bank is perfect for the everyday user who needs a reliable backup for their smartphone during a busy day out. I used it to keep my phone charged while navigating and taking photos at an event, and it performed its basic function well.

If you regularly need to charge laptops, tablets, or multiple devices simultaneously, you should definitely skip this one. It’s strictly for basic smartphone top-ups.
