6 Best Portable Chargers Under $100 (2026)
Six power bank picks with two-packs, built-in cables, a lipstick-size pair and a 60000mAh giant, compared on speed, capacity and airline rules.
At a Glance
A bigger budget does not just buy a bigger battery, it buys flexibility. Three of these picks are two-packs: the Miady and AsperX each give you a pair of 10000mAh banks, and the HETP gives you two lipstick-sized 5200mAh banks with a built-in USB-C connector. At the other extreme, the LILIO packs 60000mAh into a single pack that charges five devices.
Where the earlier budget tiers force a choice between slim and large, this one lets you buy a pair, one for home and one for the bag. The GrnOas.E and the Aaoyun each focus on a single 10000mAh bank with built-in cables or a metal body, and both support 22.5W charging. That makes the spread between picks as much about how you live as how much power you need.
We ranked these six by everyday usefulness, how much hardware you still have to carry and whether the capacity makes sense for flying. Watt-hour math is included so the LILIO's cabin limits are clear, and each pick is tied to the type of buyer it fits.
6 Criteria to Look For Before Buying a Portable Chargers Under $100 (2026)
Key buying criteria so you get the right fit the first time.
Capacity in watt-hours
Compare banks by watt-hours, roughly mAh divided by 1000 times 3.6 to 3.7 volts. The Miady's two 10000mAh banks are about 37 Wh each, the HETP's 5200mAh banks are about 19 Wh each, and the LILIO's 60000mAh is about 222 Wh. Airlines allow 100 Wh or less in the cabin without approval and 100 to 160 Wh with approval, so the LILIO exceeds even the approval tier. Always look for a printed Wh rating, since security may confiscate banks without one.
Pack of two versus one big pack
Two smaller banks can beat one huge bank because they give redundancy, sharing and easier flight rules. The Miady and AsperX give you two 10000mAh banks, while the LILIO packs everything into a single 60000mAh unit. If one pack fails or runs flat, the pair keeps you going, whereas the LILIO is a single point of failure. A pair also means each bank stays under the 100 Wh cabin limit.
Charging speed in watts
USB-C PD 3.0 spans 18 to 100 W, while typical USB-A ports provide only 5 to 12 W. The Aaoyun, GrnOas.E and LILIO all advertise 22.5W, which refills a phone quickly. The Miady and AsperX listings focus on steady charging without calling out wattage, so they feel slower. Short, quality cables lose less power, which helps built-in cables on the GrnOas.E and Aaoyun.
Built-in cables and connectors
Built-in cables remove the biggest failure mode of a power bank, which is a missing cord. The GrnOas.E carries two built-in cables, the Aaoyun carries one USB-C cable and the HETP has a USB-C connector built right into the body. The catch is that a frayed built-in cable cannot be replaced. The Miady and AsperX avoid this by using your own cords.
Usable output versus rated capacity
Delivered energy is lower than the label, with independent measurements showing roughly 77 to 83 percent of rated capacity. That means a Miady bank's 37 Wh behaves more like 30 Wh in use, or about two phone charges. The LILIO's cell scales that to many charges, though conversion losses still apply. Treat any charge count in a listing as a ceiling.
Safety marks and protections
Look for UL or FCC marks and built-in protection against overcharge and short circuit. Large banks like the LILIO concentrate a lot of energy, so safety matters more as capacity grows. Keep any bank out of hot cars and replace one that swells or runs unusually hot. Treat all capacity figures here as seller claims.
6 Best Portable Chargers Under $100 (2026)
Miady 2-Pack 10000mAh Power Banks
About this pick
The Miady is the best all-round buy because it solves the most common power bank problem, which is that the one you need is always at home. You get two slim 10000mAh banks, so one can stay charged on a desk or bedside table while the other lives in a bag. Each bank has three outputs and two inputs, so a phone, a tablet and earbuds can all charge at once.
The USB-C port works for both input and output, which means the same port refills the bank and charges a device. There are no built-in cables, so you will need your own cords, and the speeds are steady rather than the quickest.
In ownership the pair is simple to live with because each bank is about 37 watt-hours, well inside the 100 Wh cabin limit, and you can take both on a plane. Sharing between two people is easy too. Compared with the AsperX it offers the same two-pack concept with an extra input, and compared with the LILIO it trades raw capacity for portability and redundancy.
Best for: Couples, families and anyone who wants a backup bank for home and another for the bag.

- Banks: 2 x 10000mAh
- Outputs: 3, with 2 inputs
- USB-C: Input and output
- Cabin use: Each bank within flight limits
Pros
- +Two 10000mAh banks give redundancy and sharing
- +Three outputs charge several devices together
- +USB-C port works for input and output
- +Each bank stays within cabin limits
Cons
- −No built-in cables, so bring your own cords
- −Slower than the 22.5W single banks
GrnOas.E 10000mAh 22.5W Power Bank with Built-In Cables
About this pick
The GrnOas.E is the grab-and-go choice because two cables are built into the body, one for iPhone and one for USB-C. It combines PD and QC fast charging at 22.5W, and the USB-C port plus extra outputs let it charge four devices at once. With no separate cord, there is nothing to forget at home.
The tradeoff is that the built-in cables cannot be swapped if they fray, so the cables become the weak point over time. It is also a single 10000mAh pack, so it gives roughly two phone charges rather than the doubling of a two-pack. That fits a daily carry bank better than a long trip supply.
In daily use it is the simplest bank here because you only need to carry one object. At about 37 watt-hours it clears cabin rules easily. Compared with the Aaoyun it adds a second built-in cable and more outputs, while the Aaoyun has a metal body and a stronger heat claim.
Best for: People who forget cables and want one object that charges both iPhone and Android.
Check price on AmazonSpecs
- Capacity: 10000mAh
- Fast charging: 22.5W PD and QC
- Cables: iPhone and USB-C built in
- Outputs: 4, with 2 inputs
Pros
- +Two built-in cables so no cord needed
- +22.5W PD and QC fast charging
- +Four outputs charge several devices at once
- +Cabin-friendly 10000mAh size
Cons
- −Built-in cables cannot be replaced if damaged
- −Single bank, so no backup or sharing
AsperX 2-Pack 10000mAh Power Banks
About this pick
The AsperX is another two-pack of slim 10000mAh banks, sized to slip into any pocket or backpack. Each bank has one USB-C and two standard USB ports, so it can juice up three devices at once. The USB-C port works as both input and output, matching newer iPhones, iPads and USB-C devices.
The listing does not call out fast charging wattage or built-in cables, so treat it as a steady, reliable pair instead of a speed demon. You will need to bring your own cords. That is a fair tradeoff for having two banks to share or rotate.
It is a solid choice if you like the two-pack idea and want a plain, no-frills version. At about 37 watt-hours per bank, both are comfortable inside cabin limits. Compared with the Miady it gives up the extra input listed on the Miady, but the core experience of two banks is the same.
Best for: Buyers who want a plain pair of banks to share or rotate between home and bag.
Check price on AmazonSpecs
- Banks: 2 x 10000mAh
- Ports: 1 USB-C plus 2 USB
- USB-C: Input and output
- Charges at once: 3 devices
Pros
- +Two 10000mAh banks in one pack
- +USB-C port handles input and output
- +Three ports charge three devices at once
- +Slim size slips into pockets
Cons
- −No fast charging wattage called out
- −No built-in cables
Aaoyun 10000mAh 22.5W Power Bank
About this pick
The Aaoyun is a single 10000mAh bank with a built-in USB-C cable and a 22.5W PD output. The listing describes a CNC-machined aluminum alloy case only 0.6 inches thick that it says dissipates heat faster than plastic rivals. It also says the bank charges an iPhone 16 or 17 to 63 percent in 30 minutes, which is a seller claim.
The tradeoff is that you only get one bank and one built-in cable, so it will not match the redundancy of a two-pack. You still need your own cord for a second device. It is, however, the slimmest and most polished single bank here.
In ownership it is easy to pocket and fast to refill, and 10000mAh is about 37 watt-hours, within cabin limits. Compared with the GrnOas.E it has a metal body but fewer outputs, and compared with the Miady it offers faster charging in a single bank rather than a pair.
Best for: People who want a premium-feeling, fast single bank with a cable attached.
Check price on AmazonSpecs
- Capacity: 10000mAh
- Fast charging: 22.5W PD
- Cable: Built-in USB-C
- Body: CNC aluminum alloy, 0.6 in
Pros
- +Built-in USB-C cable attached
- +22.5W PD charges quickly
- +Metal body feels sturdy and sheds heat
- +Thin 0.6 inch body fits pockets
Cons
- −Only one bank, so no backup
- −Single built-in cable, so extra devices need a cord
HETP 2-Pack 5200mAh USB-C Power Banks
About this pick
The HETP gives you two tiny banks with a built-in USB-C connector that plugs directly into the phone. Each bank is about the size of a lipstick, so it slips into a pocket or a small purse. The listing says it is designed for iPhone 17, 16 and 15 series and for Android phones with USB-C.
The tradeoff is compatibility and capacity. It does not work with Lightning iPhones, and thick cases can block the connector, so check your case first. At 5200mAh per bank you get roughly one top up per bank, which is a quarter of the 10000mAh packs' energy in each unit.
It is a clever, no-cable solution for light users who just want an emergency boost. The two-pack means one stays in a coat and one in a bag. Compared with the Miady it is far smaller and more convenient but far less capable, and it is the lowest-capacity pick in the guide.
Best for: USB-C phone owners who want a tiny, cable-free emergency top up.
Check price on AmazonSpecs
- Banks: 2 x 5200mAh
- Connector: Built-in USB-C
- Size: About lipstick size
- Fits: iPhone 15 to 17 and USB-C Android
Pros
- +Built-in USB-C connector means no cord
- +Two lipstick-sized banks in the pack
- +Easy to tuck into a pocket
- +Works with USB-C Android phones
Cons
- −Thick cases can block the connector
- −Does not work with Lightning iPhones
LILIO 60000mAh 22.5W Power Bank
About this pick
The LILIO is the power station of this lineup, with a 60000mAh cell, 22.5W PD fast charging and a 3-in-1 braided cable. The listing says it can charge five devices at once and includes an LED display, and it markets itself for camping and road trips. That capacity is built to power a household through a weekend or an outage.
At about 222 watt-hours, it is well above the 160 Wh limit, which is not allowed on commercial flights per the airline tiers. It is also heavy and bulky, so it belongs in a car, a tent or a storage closet rather than a pocket. Recharging it also takes a long time, so plan to plug it in overnight.
If you want maximum energy from a single pack, nothing else here compares. Compared with the Miady pair it offers triple the capacity in one unit but no flight option and no redundancy. It is the highest cost tier in the group, so only choose it if you will use the capacity.
Best for: Campers, drivers and outage planners who want maximum capacity in one pack.
Check price on AmazonSpecs
- Capacity: 60000mAh
- Fast charging: 22.5W PD
- Cable: 3-in-1 braided
- Display: LED
Pros
- +60000mAh holds a week of phone power
- +22.5W PD fast charging
- +Charges five devices at once
- +LED display shows remaining charge
Cons
- −Heavy and bulky, not a pocket carry
- −Too large for airline cabin use
How We Evaluated These Portable Chargers Under $100 (2026)
Each pick was assessed across 5 criteria weighted for real-world use.
Capacity and flight rules
We converted each listed mAh figure into approximate watt-hours so the Miady and AsperX pairs, the HETP pair and the LILIO could be compared on one scale. We checked each against the 100 Wh cabin tier and flagged the LILIO as exceeding even the approval tier. Packs well inside the limit scored better for travel.
Charging speed
We compared stated wattage, from the 22.5W Aaoyun, GrnOas.E and LILIO to the unlisted speeds on the Miady and AsperX. A pick scored well if its fastest port is genuinely quick for a phone. Where a listing did not call out speed, we treated it as steady rather than fast.
Cables and connectors
We counted built-in cables and connectors, since a forgotten cord is the top reason a bank fails. The GrnOas.E stood out with two built-in cables and the HETP with its built-in USB-C plug, while the Miady and AsperX rely on your own cords. Cable replaceability was weighed as a durability risk.
Portability and redundancy
We compared size and the value of having two banks, from the lipstick-sized HETP pair to the LILIO's single large pack. The strongest pick for flexibility was the Miady and the most basic in capacity was the HETP. The LILIO was scored for capacity but marked down for size and flight limits.
Value at this budget
We judged what the buyer gets relative to the other five, such as a pair of 10000mAh banks against one 60000mAh unit. Based on product specs and buyer feedback signals, the Miady offers the strongest all-round value and the LILIO the strongest for raw capacity. No pick was favored because of paid placement.

Pair of Small Banks vs One Large Pack
The core tradeoff is redundancy and flight rules versus raw capacity.
Pair of small banks
The Miady, AsperX and HETP give you two banks, so one can live at home and one in a bag. Each stays under 100 Wh and clears cabin rules, and if one fails you still have another. The Miady is the pick of these.
One large pack
The LILIO holds about 222 Wh in a single unit, powers five devices and suits camping or outages. It is heavy, exceeds airline limits and has no backup if it fails.
Recommendation
Pick the Miady for daily life and travel, and the LILIO only for trips or outages where no outlet is available.
Built-In Cable vs Bring Your Own Cord
This decides how much hardware you pack.
| Preference | Recommended pick |
|---|---|
| Two built-in cables for iPhone and USB-C | GrnOas.E 10000mAh 22.5W Power Bank with Built-In Cables |
| One built-in USB-C cable with a metal body | Aaoyun 10000mAh 22.5W Power Bank |
| Plug straight into the phone | HETP 2-Pack 5200mAh USB-C Power Banks |
| Prefer replaceable cords | Miady 2-Pack 10000mAh Power Banks |
| Prefer replaceable cords and a plain pair | AsperX 2-Pack 10000mAh Power Banks |
For Flying and Travel Specifically
Look for
Choose banks at or under 100 Wh and carry them in your cabin bag, never checked luggage. A printed Wh rating helps at security, and 10000mAh at about 37 Wh clears every tier.
In this comparison
The Miady, AsperX, GrnOas.E, Aaoyun and HETP all fall well under 100 Wh. The LILIO at about 222 Wh exceeds the 160 Wh upper tier, so leave it out of any plan involving a flight.
When to Spend More
Spend more if
You want two banks for redundancy, which makes the Miady worth the step up, or you need maximum capacity for outages, where the LILIO is the strongest value. A metal body and fast charging on the Aaoyun also justify the step up from plainer options.
Save if
You only need an occasional emergency top up, which makes the Aaoyun or the HETP enough. Save on the AsperX if you want a plain pair without fast charging.
Frequently Asked Questions
Should I buy a two-pack or one large power bank?
A two-pack such as the Miady gives you redundancy, sharing and easier flight rules, since each bank stays under 100 Wh. One large pack like the LILIO simplifies charging but is heavy and a single point of failure. For daily life and travel, a pair is usually the smarter choice.
Is it worth spending more for a bigger budget?
At this budget you gain flexibility rather than just capacity, such as two banks, built-in cables or 22.5W charging. The Miady pair and the GrnOas.E show that spending more buys convenience. If you only need an occasional boost, a single bank like the Aaoyun is enough.
How long do power banks last?
Lithium cells lose capacity with every charge cycle, and heat shortens their life. Keep banks out of hot cars and avoid draining them to zero every day. Built-in cables on the GrnOas.E and Aaoyun can also become the weak point if they fray.
Does 60000mAh mean I can charge my phone 20 times?
Not quite, because usable output is only about 77 to 83 percent of the rating. The LILIO's 222 Wh behaves more like 175 Wh in practice, which is still many phone charges. Phone battery size, cable quality and charging speed all change the count.
Can I fly with these power banks?
Yes for most, but carry them in your cabin bag. The Miady, AsperX, GrnOas.E, Aaoyun and HETP are under 100 Wh and allowed without approval. The LILIO at about 222 Wh exceeds the 160 Wh upper limit and should not go on a flight.
Do tiny lipstick-size banks work with every phone?
No, the HETP has a built-in USB-C connector, so it works with iPhone 15 to 17 and USB-C Android phones but not Lightning iPhones. Thick cases can also block the connector. Check your phone and case before buying.
Is 22.5W fast charging worth having?
Yes if you charge on the go. A 22.5W port such as the Aaoyun's or the GrnOas.E's refills a phone much faster than the 5 to 12 W typical of USB-A ports. If you charge overnight, the steady speeds on the Miady or AsperX are fine.
