30000mAh power banks are real workhorses when it comes to providing power for sustained periods of time. They’re especially useful for charging laptops several times over. However, since they have a capacity of around 111 Wh, they can’t be taken on flights without a special permit (read more). This is why they tend to be less popular than 20000mAh power banks which are under the 100Wh limit imposed by the TSA, FAA, and other flight organizations.
Since we write about power banks on a daily basis we decided to create this curated list of what we believe to be the best 30000mAh power banks. The list is intended to be dynamic so that when we discover a new model that we believe it should be mentioned, we simply amend the list. Thus, if you come back at a later time, you might find different models and/or a different order.

The ROMOSS SENSE8+ is one of the most affordable 30000mAh power banks. For a pretty low price, you can get a power bank that not only has a huge capacity, but it also comes with a bidirectional USB type C port, an input Lighning port, and two USB type A ports which are Qucik Charge-compatible.
It can provide up to 12.6 charges to the iPhone 8, 4 charges to the Nintendo Switch, and 4 charges to the iPad Pro. Its maximum power output is 18W, which is enough to quickly charge the average smartphone or tablet.
However, it does have some downsides too. For once, the 18W power output is not enough for charging power-hungry laptops. It also does not feature Power Delivery, which would have come in handy for the USB type C port. But most of all, it has a pretty lengthy recharging time of 11 hours. Compared to its competitors, this is quite slow.
All-in-all, the ROMOSS SENSE8+ is the perfect choice for you if you’re looking to get the most capacity for the least investment and if you don’t care about things such as being able to charge laptops or the power bank’s recharging time.

The POWERADD Pilot Pro 5 is a solid unit that offers multiple charging options. For starters, it comes with Power Delivery 3.0 which provides a 60W power output, enough to charge most laptop models including the MacBook Pro. Furthermore, included in the package are a set of 10 different power adaptors for various other laptop models such as Toshiba, Lenovo, Dell, HP, Acer, Asus, Samsung or Sony.
Another very rare feature of the POWERADD Pilot Pro 5 is the fact that id comes with one DC input port and with one DC output port. Furthermore, included in the pancake is a DC to DC cable, which can be of great help especially when used in conjecture with the 10 adaptors previously mentioned.
It’s also worth mentioning that it comes with an LED display that showcases important information such as the battery charging level or which ports are currently in use. This can be a very handy feature, especially being able to see the exact amount of power left in the battery, as opposed to having to estimate it as it happens with the classic power banks that only have 4 LED lights to showcase the charging level.
Last but not least, we’d like to mention its ultra-fast charging time of under 3 hours! For a portable charger of this size, being able to charge in under 3 hours using a fast charger, is a great accomplishment and it’s a factor to be seriously considered when making a buying decision.
How many charges will a 30000mAh power bank provide?
As previously discussed on our site, the real capacity of a power bank is smaller than it’s actual capacity. Roughly speaking, you’ll get about 75% of the listed capacity. So a 30000mAh power bank will provide an actual charge of around 22500mAh. Listed below are some popular battery capacities which you can find in mobile phones. Check how much capacity your phone’s battery has and you can estimate the number of chargers you can expect from a 30000mAh portable charger.
|Phone battery capacity||Number of chargers by 30000mAh power bank|
For example, the iPhone 12 has a battery capacity of 2227mAh. This means that you can expect about 10 full chargers from a 30000mAh power bank and not 13.5 as it would seem at first sight from the listed capacity.
How to take a 30000mAh power bank on a flight
Since the max limit for Li-Ion batteries imposed by the FAA is 100Wh, 30000mAh power banks don’t make the cut. But they’re not completely forbidden also. Batteries between 100Wh and 160Wh can be taken on board, however, they require a special permit.
So in order to fly with your 30000mAh power bank, you’ll need to contact your airline beforehand in order for them to help you receive the special permit. It would also be a good idea to contact all the airports you’ll be passing through, too. Especially if you’re traveling internationally. It’s possible that local airports from foreign countries have stricter rules. So to avoid any type of unpleasant situations, it’s best to get in touch with the airports as well, not only with the airlines.
Also, remember that you’re allowed to have a maximum of two different batteries with you. So if you have another power bank of equal or smaller capacity, you’ll be fine. But if you have 3 or more, you’ll most likely have to let one or more of them go at the security checkup.
