Top 10 Best Portable Power Banks Reviews

You had a long day at work. You and your girlfriends went out after work to unwind and have fun. Midnight rolls around, and you’re ready to go home.

You reach into your purse to schedule an Uber, but your phone is completely dead.

We’ve all been there at some point or another. For me, my phone always seems to die when I’m driving on a long trip. There’s nothing more annoying than having to stop at a travel station in the middle of the night waiting for your phone to charge.

That’s where power banks come in.

Portable power banks function a lot like a battery. They store a limited amount of energy, measured in milliamp hours (mAh). The most basic power banks will typically provide your phone or tablet with one full charge. Some models can charge your electronic device three or four times before being recharged.

You live a busy life. You need a power bank able to accommodate your busy schedule. This list will help direct you towards the ten best portable power banks on the market.

What You Should Know

Power banks are as different from one another as cell phones. Different cell phones don’t all have the same batteries, and power banks are the same way. In order to get the most out of your purchase, there are some things you need to consider.

Keep in mind that an ideal power bank for an iPhone may not be the same for an Android. You should always check the mAh of your phone battery before buying a power bank. It will go a long way towards ensuring you get the right one for your needs.

1. Milliampere Capacity

As I mentioned in the introduction, all power banks have a certain energy capacity. The amount of juice stored in a power bank determines how many times you can use it to charge your phone before you need to power up the power bank itself. The number of charges you get is heavily influenced by your device’s battery capacity.

2. Voltage

It’s not enough for a power bank to have enough energy capacity. It must give out current at a certain voltage to be able to charge the phone quickly which is known as Quick Charge Technology. That is why make sure that the power bank you buy has a Quick Charge technology.

3. USB ports

Most power banks incorporate USB technology. Some have just one USB port; others have several. If your power bank has a high mAh capacity, it may be able to charge several devices up simultaneously – if it has enough USB ports to do so.

4. Size

Some power banks are more portable than others. Ideally, you want a power bank roughly the size of a thick credit card or a lipstick container, something that will fit comfortably in your purse or your pocket.

5. Price

As a rule, power banks aren’t particularly expensive, but there are always exceptions. Most people will be satisfied with a power bank for $100 or less, but there are premium options available. Since your power bank is rechargeable itself, there is a law of diminishing returns for the most expensive models.


The ideal power bank is the best of both worlds – high milliampere capacity, multiple USB ports, lost price point. The Power Banks RAVPower 22000mAh Portable Charger delivers on all three counts.

Energy capacity of 22,000 mAh

Three USB ports lets you charge multiple devices

Includes two micro-USB charger cables

Current output of 5.8 amps

Backed by a lifetime warranty

10. Pisen Wireless Presenter 2500mAh Power Bank

For a lot of people, the main appeal of a power bank is to provide battery charging when you’re out and about and don’t have access to a standard electrical outlet. If you don’t expect to use a power bank on a regular basis, then you don’t need to spend a lot of money on one.

Fortunately, there are a lot of great low-priced power banks on the market. The Pisen 2500mAh Wireless Presenter is one of my favorite budget models. It’s just over five inches long, and it has a couple of nice features that help to set it apart from other similarly-priced power banks. The main appeal of this particular model is the laser pointer. The 3 mW laser is very bright and can reach up to 328 feet, and the 2500 mAh power bank is capable of providing a complete charge to almost any device at least once.

The Pisen runs on a single rechargeable lithium-ion battery and is rated to hold its charge for up to half a year. The power bank has a single USB port, and it comes with a micro-USB charger cable. The power bank/laser pointer is backed by an 18-month warranty. The laser pointer is designed to interact with Microsoft software, making it a perfect piece of electronics for a professor or business professional.


● 2500mAh capacity
● Includes 2.4 GHz laser pointer
● Backed by 18-month warranty


● Laser pointer may not be visible against LED screens

9. Anker PowerCore+ mini, 3350mAh Portable Charger

If you’re looking for an ultra-compact power bank with a little bit more juice than the Pisen Wireless Presenter, you may be interested in the Anker Powercore+ mini. This miniaturized portable charger is only 3.7 inches long, roughly the size of a lipstick container.

With 3350mAh of energy, the PowerCore+ mini offers more charging time than the Pisen at the same price point. In addition to its traditional USB port, it also has a micro-USB input, and it comes with a micro-USB charger cable as well. The power bank uses a one amp adapter that can charge your phone to 100% in as little as three or four hours.

Like the previous power bank, the Anker PowerCore+ is backed by an 18-month warranty, and it even comes with a handy travel pouch. Its super small size makes it an ideal portable charger, as its small enough to fit inside a coat pocket or pants pocket without feeling cumbersome. However, they do have a shelf life, and they cannot be expected to work reliably after the 18-month warranty expires. Fortunately, the low price point makes replacing them a simple matter.


● 3350mAh capacity
● Compact size less than 4 inches long
● Backed by 18-month warranty


● Functionality unreliable after a warranty expires

8. Anker PowerCore 10000

If you need something that can give you more than one charge, or something with enough power to charge multiple devices consecutively, the Anker PowerCore 10000 might be more your speed. The PowerCore 10000 measures 2.36 x 3.62 x 0.87 in and weighs just 6.4 ounces, making it a convenient size for traveling.

With 10,000mAh, there’s enough energy here to charge a phone up to four times before the power bank needs replenishing. It has a maximum input of 2 amperes, and the power bank has both standard USB and USB-C ports. The power bank is compatible with both Apple and Android systems, and it has a power safety feature that protects you and your devices from any inadvertent surges.

7. Power Banks RAVPower 22000mAh Portable Charger

I touched upon the Power Banks RAVPower 22000 briefly in the editor’s pick. It’s an excellent value for the price, with enough amperes to charge anywhere from three to eight different phones on a single charge, depending on the phone.

There are several reasons to recommend the Power Banks RAVPower 22000. First, the charger has three separate USB ports, meaning your friends, family or coworkers can all take advantage of this to charge their devices. This is especially helpful on long trips, as most cars only have room for one phone to plugin. Another reason to like this phone is its fast charging time. It has a 2.4A input and charges at up to 5.8A.

Measuring 6.50 x 0.94 x 2.76, it’s a little larger than the other power banks, but that isn’t much of a problem, considering its superior capacity. It’s still quite portable, and it comes with a convenient carrying case, as well as two micro-USB charging cables. Perhaps best of all, the RAVPower 22000 is backed by a lifetime warranty with registration.


● 22000mAh capacity
● Comes with three USB ports
● Backed by a lifetime warranty


● Takes a long time to fully charge the phone

6. Solar Charger BERNET 24000mAh High Capacity Portable Power Bank

If you’re looking for a different take on a power bank, the BERNET 24000mAh Solar Charger Power Bank offers a new way to approach the game. Although the Solar Charger works in mostly the same way as any other power bank, the solar technology built into its design ensure that it will last a little longer than your average power bank.

The solar technology allows for an 8% conversion of electricity, so you’re not going to get a huge boost from it. But that extra conversion would be enough to at least partially charge your phone in an emergency, making this a perfect power bank for impossible-to-predict situations. With a capacity of 24000mAh, this power bank can charge an iPhone 6 up to 8 different times.

The power bank has a variety of safety features to protect your electronics from over-discharges, over-currents, and other overages. It has an auto-shutoff so you don’t have to worry about damaging your electronics. The Power bank also has plenty of connections, with three USB ports and two micro-USB connections. Considering the price, this is a very effective and reliable power bank.


● 24000mAh capacity
● Comes with three USB ports
● Solar technology provides 8% conversion


● More sensitive to damage than other power banks

5. Battery Pack RAVPower 26800 Portable Charger 26800mAh Power Bank

The RAVPower 26800 Battery Pack portable charger provides even more room for your family and colleagues to share with you. With three separate USB ports as well as a micro-USB, there’s room for everyone to get the charge they need.

With nearly 27,000mAh of capacity, you can charge your phone seven to nine times with this power bank, or as many as three times for a tablet. The power bank has an easy-to-read light display one side that keeps you abreast of the battery storage, and the power bank can support both 2.4A and 5.5A outputs.

The rechargeable batteries in this power bank are rated for up to 500 recharges, and the bank is protected under warranty for 30 months. All said and done, it’s a very nice power bank, and is the last entry-level power bank on this list. It’s a little larger than the other models listed, making it really too large for a pants pocket. But it’s not too big for a purse or jacket pocket.


● 26800mAh capacity
● Comes with three USB ports
● Backed by a 30-month warranty


● A little larger than some power banks

4. Kinkoo® Infinite One 8000mAh Ultra-slim Premium Portable Charger and External Battery

There’s a lot to like about the Kinkoo® Infinite One portable charger. The price isn’t one of them. The charger is made with cutting-edge technology, to be sure, but considering the high price, the end result is a little underwhelming in some ways.

The most disappointing feature of this power bank is its small capacity. 8000MAh is a pittance considering the price of the portable charger, but some excellent features help to offset this. At less than half an inch thick, the power bank is roughly the same size and shape as an iPhone 6. It is compatible with almost any phone device under the sun, making it one of the universal power banks on the market.

In addition, the power bank is protected by an 18-month warranty and includes two micro-USB cables. Really, I have nothing bad to say about this power bank, with just one caveat. It costs roughly twice as much as the next cheapest item on the list, and it doesn’t come close to matching the energy output. All in all, the Kinkoo® is still worth buying, but its high price makes it harder to recommend.


● 26800mAh capacity
● Comes with two micro-USB charging cables
● Backed by 18-month warranty


● Rather expensive

3. Crave PowerPack CRVPP101 50000mAh Ultra-High Density Portable Power Bank

Now, this is more like it. This is a price jump that I don’t struggle to understand or rectify. The Crave CRVPP101 PowerPack offers a whopping 50,000maH of energy capacity, providing you with 15-20 full charges.

There’s a lot more good where that came from. The power bank has four separate USB ports, as well as line outs of both 12 and 20 volts, allowing you to use this to charge not only your cell phone and tablet but your laptop as well, although you’re only likely to get a single charge for your computer.

All said and done, this is a very capable power bank, versatile enough for almost any situation. The ability to charge your laptop is especially helpful if you need to work during lunch and there are no outlets available at a restaurant – a situation I am all too familiar with. The only real downside of this power bank is its weight. It weighs three pounds, making it undesirable to carry around in your pocket or purse. Still, this power bank is a must for business professionals.


● 50000mAh capacity
● Includes 12- and 20-volt laptop connections
● Features four USB ports


● Too heavy to carry around in your pocket

2. Portable 27000mAh 85W / 110V Battery Pack by ChargeTech

Like the Crave PowerPack, the ChargeTech 2700mAh portable battery pack offers not just USB ports but laptop connections as well, allowing you to effectively recharge any electronic device on the go. This is a premium power pack and carries a hefty price tag, but it goes above and beyond the call of duty.

This 27000mAh power pack is far more than just a charger for your phone or laptop. This portable pack from ChargeTech includes a standard 110V AC outlet, allowing you to plug almost any electric device for emergency support, although it recommends maxing out at 85 watts – so don’t try to run a microwave on this! The power pack uses FastCharge technology that delivers 2.4A to your electric devices, charging them in as little as two hours.

Measuring 7.5 x 5.2 x 1 inches and weighing 2.5, this portable power pack is the perfect size for your backpack or briefcase and is ideal for business meetings and other situations where you may spend an extended period of time away from a power outlet while using your laptop, effectively extending your battery life considerably. The price tag is pretty steep, so this isn’t for everyone, but if you need the best, this is pretty close to the top of the food chain.


● 27000mAh capacity
● Includes 110V AC outlet
● Rated for up to 85W.


● Too heavy to carry around in your pocket

1. Portable 42000mAh 250W / 110V Battery Pack by ChargeTech

Our last entry is a scaled up-version of the previous power pack. It has a relatively high price point, but it also doubles up – not quite literally – on everything the previous portable battery did well.

The previous power pack could store 27000mAh. This model can store 42000mAh. The previous model was rated for up to 85W for its AC outlet. This unit is rated for up to 250W. Plus, it can be combined with a solar panel charger to minimize the drain from charging and slowly build up the reserves when not in use.

The vast majority of people aren’t going to need something this powerful. If you’re looking for straight milliampere hours, there are models that have greater storage that cost $200 less. But if you need something that gives you the freedom to plug into an electrical outlet – for whatever reason – this is as good as it gets.


● 42000mAh capacity
● Includes 110V AC outlet
● Rated for up to 250W.


● Quite expensive
