1. Usb Pd Power Bank Anker

If you are like me who uses a smartphone a lot, then you’d understand the importance of carrying a backup power bank (A.K.A portable charger).

Some of the portable chargers are capable of even charging your laptops, so it becomes handy when you are traveling or go hiking.

But as you may know, there are lots of power banks are available on the market.

Which is the best brand for power banks?

In our opinion, Anker is the best and most popular brand for power banks because of its great features and affordable price range. However there is a lot of models offered by Anker such as Anker PowerCore / PowerCore+ / PowerCore / Astro. As all of them have different features and functions, it is hard to choose any one of them.

So which Anker power bank is best?

Well, this question is hard to answer as there are so many Anker power banks are available. First of all, you would need to identify your needs such as do you need a power bank to fast charge any specific device (Apple/Samsung) or do you need a power bank with higher capacity or do you need a fast charging capability and so on.

So to save you the legwork we have reviewed many Anker portable chargers according to their capacity, charging speed, ease of use, and warranty.

And after testing so many power banks, we came up with the reviews of Best Anker Power Banks.

You can use these Anker power banks to charge your Smartphone, Nintendo Switch, GoPro Cameras, and laptops as well.

Best Anker Power Banks for iPhone and MacBook.

The iPhone 8/8+, iPhone X, XS, XS Max, XR, MacBook, iPad Pro, and Google Pixel models support the fast charging known as USB-C PD (Power Delivery), and there are only few Anker power banks available that features the USB-C PD technology. Using this power bank, you can charge your iPhone up to 50% in 30 minutes. Also, all these power banks are rapid charging (2.4 amp) supported meaning that you can charge your Samsung S9, S8, S7, Note 9/8 or any USB-C compatible devices relatively faster then included wall charger.

Also, these Anker power banks come with 2.4 amp rapid charging (USB port) so if you own an iPhone 7/7 plus/6/6s/6 plus or LOWER MODELS then it will recharge your device faster than your included Apple wall charger.

Please note that all these power banks come with the fast charging technology known as USB-C PD so they are expensive than other Anker power banks. So if you do not wish to charge your Apple device faster then you can choose the normal Anker power banks mentioned in the third table which are relatively cheaper.

None of these power banks include a USB-C to Lightning cable. In order to fast charge your Apple device, you would need to purchase the separate USB-C to Lightning cable. You can choose either Anker Powerline II USB C to Lightning Cable OR Apple Lightning to USB-C Cable (2 m).

So here are Anker power banks that support the USB-C PD fast charging.

Best Anker Power Banks for Samsung and other Quick Charge Supported Devices.

Now here is the list of Anker power banks that support the Quick Charge 3.0/2.0 as input and output. Most of the smartphones (Samsung Note 5/Note 8/Note 9/S6/S7/S7 Edge/S8/S9/S10) are compatible with Quick charge 2.0 and 3.0(Backward Compatible too). So using this power bank, you can charge your device up to 80% in less than 35 minutes.

Please note that all these power banks come with the fast charging technology known as QUICK CHARGE 3.0/2.0 so they are expensive than other Anker power banks. So if you do not wish to charge your Samsung device faster then you can choose the normal Anker power banks mentioned in the third table which are relatively cheaper.

Best Anker Power Bank for Non-Quick Charge or PD supported Devices.

If you have a smartphone that doesn’t support Quick charge or PD fast charge, then we recommend following Anker power banks with 2.4 amp rapid charge with PowerIQ 2.0 technology to fast charge any devices. These power banks are relatively cheaper and feature fast recharging capability.

Things you should consider when buying a power bank.

The mAh Rating.

mAh rating means the storage capacity of the power bank. If you want to charge your phone multiple times on a single charge, then you should go for higher mAh rating power banks.

Versatility

Versatility is worth considering when you are looking for a power bank that can charge multiple devices at the same time.

Fast Charging Capability

All smartphones use different fast charging technology to speed up the charging process. For example, Apple uses the USB-C PD fast charging, Oneplus uses the Dash charge and Samsung uses the Quick Charge3.0/2.0. So in order to charge your smartphone through power bank at high speed, you would need to use the fast charging compatible power banks.

That is why this one of the essential factors to consider when choosing any power bank. All the below reviewed power banks are compatible with Quick Charge, Power Delivery fast charge, and even Rapid Charge.

Compatibility

When buying a power bank, you should check if it is compatible with your phone. So like I said earlier you will just have to check if the output port is the same as phone other then that these latest technology power banks will be compatible with all of your devices.

Recharging Time.

Let’s say you bought a great power bank that quickly charges your device but what if it takes forever to recharge the power bank. Why would anyone wait that long? So always choose a power bank that recharges quickly.

Number of Ports.

If you want to charge let’s say 3 devices at the same time, then there might be some instances when typical power bank won’t have three ports, or they won’t have the capability of simultaneous charging. At that time you would need to buy the power bank with 3 or 4 charging ports.

Quick Charge 3.0 vs. Quick Charge 2.0 vs. Samsung Fast Charge vs. iPhone 2.4/3 amp Rapid Charging vs. USB-C PD

Qualcomm® Quick Charge 3.0 is supported by some of the latest smartphones such as Sony Xperia XZ/ XZ1/XZ2 and some LG and Nokia devices. Using this technology, you will be able to charge your phone up to 80% in 35 minutes. Click here to get the full list of Quick Charge 3.0 compatible device.

Quick charge 2.0 is also an impressive fast charging technology which is supported by most of the smartphones such as Samsung S9, S8, S7, S6, etc.

Apple devices (below iPhone 8 models) does not support fast charging, but they only support the 2.4 amp Rapid charging which is not that bad. Most of the Anker power bank comes with a 2.4 amp rapid charging feature.

USB-C PD (Power delivery) is the same as fast charging, and it is supported by Apple devices such as iPhone 8, 8+, iPhone XS, XS Max, XR, and iPhone X. It usually charges the phone up to 50 % in 30 minutes.

Difference between all the Anker power bank series

Anker has released many power bank series over the time such as Anker PowerCore, Anker PowerCore+, Anker PowerCore ll, Anker Astro, Anker PowerWave, Anker PowerCore Lite, Anker Redux and so on. Naruto ultimate ninja storm 4 download.

In all of them, many power banks are outdated, but you will still see them on Amazon. Many people still buy them because of their great reviews, but the fact is they are terrible at charging your device and charging the power bank itself.

Anker PowerCore (Some older versions) and Astro series are one of the oldest in all of them. They are being replaced by Quick Charge power bank series known as PowerCore+ and PowerCore Speed series.

Choose PowerCore+ and PowerCore Speed over any other old series.

Anker has released so far two new series which are PowerCore and PowerCore+ followed by subcategory power banks such as PowerCore Speed and ll in 2018. However, they have discontinued the old Astro and PowerCore (Some old submodels) series long ago.

But some merchants are still selling the old Anker power banks and that too at higher price rates. Anker is continuously updating its power banks to provide users with better technology and efficiency.

For example their new released power banks; PowerCore II Slim 10000 and PowerCore II 20000 both offer PowerIQ 2.0 (0 to 50% in 35 minutes), fast charge support for most of the smartphone, power bank charging time under 5 hours and dedicated 3A rapid charging for non-compatible devices. They both offer this much functionality at the same price compared to their predecessor which does not include any of these features.

PowerCore+ and PowerCore Speed power banks are better than PowerCore Lite and PowerCore Redux.

Anker has introduced PowerCore Lite and Redux series in mid-2018 as their latest power banks. Although they are recently released and looks much slicker & cooler, they are actually slow in charging smartphones as well as power bank itself. Also Redux/Lite series is heavier and bulkier than the PowerCore series.

For example, PowerCore Speed 20000 (3.5 Hours) and PowerCore+ 10050 (5.6 Hours) supports Quick Charge 3.0 and can charge the compatible devices up to 80 % in just 35 minutes. On the other hand, the PowerCore Redux/Lite series takes up to more than 8 hours to charge the power bank alone and takes up to 5-6 hours to charge the smartphone.

So before buying any Anker power bank, you should check the power bank charging time and fast charging features.

Also to prevent any defraud you should always purchase the power banks from original Anker seller known as AnkerDirect.

The technology used by Anker in their latest power banks.

PowerIQ 2.0/1.0: PowerIQ technology is developed by Anker which automatically detects the connected device and automatically adjusts the output voltage to provide the fastest charging speed possible.

Almost all device supports this technology as input including Apple, Samsung, LG and much more. For example, using PowerIQ compatible power bank, you can charge the Galaxy S8 in 1.5 hours.

MultiProtect: This is another Anker exclusive technology that protects your powerbank and smartphone from any fault or malfunction. Anker is a well-known brand for taking their safety measures first.

In all of their power banks, they have incorporated 11 point suite of advanced safety and protection systems. There are so many things that can happen with your power bank from over-heating to fire and even explosion.

To prevent this kind of situations altogether, they have used the following protection system; Input High-Voltage Protection, Output High-Voltage Protection, Input Current Regulation, Output Current regulation, Automatic Current Matching, Input Short-Circuit Protection, Output Short-Circuit Protection, Static Resistance, Device Overcharge Protection, Battery Overdischarge Protection, Output Temperature Control

USB-C PD: USB-C Power Delivery is a new and advanced protocol specification that allows fast and flexible charging. This rapid charging technology is adopted by many smartphone manufacturers such as Apple and Google Pixel. Also, the Anker has also included this technology in their power bank to provide fast charging capability. It supplies up to the 20 times more power than standard USB and thus charging speed increases resulting in 50% charging in just 30 minutes.

Qualcomm® Quick Charge™: Quick Charge technology is designed by Qualcomm that draws more power than previous standard protocols without sacrificing the lifespan of a battery. With its mind-blowing technology, you can charge your smartphone 4 times faster than normal 1A charging standard. The Quick Charge 3.0 is also backwards compatible with Quick Charge 2.0 and 1.0.

1. Mophie Powerstation AC

Capacity: 22Ah Outputs: 1 x AC, 1 x USB-A, 1 x USB-C

With the Mophie Powerstation AC, high power output is the name of the game. This portable laptop battery charger is able to power a 15-inch MacBook Pro. Meanwhile, the USB-C port is rated at 30W with a USB-PD label, meaning its one of the few batteries capable of fast charging an iPhone X or iPhone 8.

2. Omni 20 USB-C

For when you also need a USB hub

Capacity: 20100mAh Outputs: 2 x USB-C, 2 x USB-A Notebook Connectors: N/A

So, if you’re working and you need to charge your Nintendo Switch and a mobile device, you go for it. Plus, the Omni 20 also serves as a USB hub, clearing out some extra storage space in your bag.

• This product is only available in the US and UK at the time of this writing. Australian readers: check out a fine alternative in the Mophie Powerstation AC

3. Poweradd Pilot Pro2

Capacity: 23Ah Outputs: 1 x DC, 2 x USB Notebook Connectors: 10

The PowerAdd Pilot Pro2 doesn’t just come with 10 connectors that cover most of the laptops on the market today, but it’s backed by a two-year warranty. That means you can use the 23MAh/85Wh capacity without worry. The Pilot Pro2 is also light enough to carry around wherever you go, coming in under 560g. The only thing that holds it back is that it doesn’t have any USB-C connectors, so if you have a modern Ultrabook or MacBook, you may want to go elsewhere, otherwise you’ll have to carry a separate power supply to keep the battery charger backed up.

4. RAVPower RP-PB058

Capacity: 26.8Ah Outputs: 1 x Type-C, 2 x Type-A Notebook Connectors: 0

As technology marches forward, new laptops need less power to function. This is especially ture for high-end laptops like the MacBook Pro, HP Elite x2, Huawei Matebook Pro X or the Dell XPS 13. For all of these devices, and more, USB-C is king – the RAVPower uses this revolutionary connector to deliver up to 30W of power, which should be plenty for the best Ultrabooks. You can recharge it using a 30W wall charger that can also be used to power compatible laptops – very handy, indeed.

5. MaxOak Apple MacBook Charger

Capacity: 36Ah Outputs: 2 x Type-A, 1 x Type-C, DC-out Notebook Connectors: 3

The MaxOak MacBook Charger is a perfect example of a laptop battery charger that goes the extra mile to make sure that it matches the expectations of its audience. This portable laptop charger has all the hallmarks of an Apple device, without the logo – but that’s what those Apple stickers are for – with a matching brushed aluminum finish.

It’s the second most capacious portable laptop battery charger on this list, but its huge amount of juice comes with a catch – it carries so much power that at least one airline has outright banned it, so bear that in mind if you plan to use this charger while traveling. It’s also pretty heavy at almost 1kg and will cater to most MacBooks, but nothing else.

6. Qi-Infinity Upgraded Powerbank

Capacity: 35Ah Outputs: 4 x Type-A, DC-out Notebook Connectors: 1

The Qi Infinity Upgraded Powerbank is the only product here that targets Microsoft’s popular Surface lineup by offering the appropriate DC output voltage. It comes with a generous five ports, four of which will let you charge other 5V devices (which includes anything from other power banks to tablets and smartphones). But, what’s really interesting here is the addition of fast charging through Qualcomm’s Qi tech. You’ll be able to charge the new MacBook as well, but no traditional laptops that rely on a 19V DC output. Just keep in mind that with a capacity of 35Ah, it might not be allowed on some airlines.

• This product is only available in the US at the time of this writing. UK and australian readers, check out a fine alternative in the RAVPower RP-PB058

7. MaxOak K2

Capacity: 50Ah Outputs: 4 x Type-A, 2 x DC-out Notebook Connectors: 11

The K2 is the world’s second highest mountain and it is fitting – to some extent – that MaxOak named this battery after that lofty peak. After all, at 50Ah, this is the biggest battery on our list and one that is also the heaviest of the lot. It supports laptops up to 60W (3A, 20V) as well as fast-charging.

Note that it takes up to eight hours to charge the battery and that can only be achieved via a proprietary charger. Sadly, it doesn’t carry a USB Type-C connector – which makes it useless for newer laptops – and you won’t be able to lug it around on the plane (as with the previous two peripherals, the massive capacity here may mean it’s banned on some flights).

8. Sandberg Powerbank 20000

Capable, powerful battery charger

Capacity: 20Ah Outputs: 2 x USB Type A, 1 x DC-out Notebook Connectors: 12

Sandberg's Powerbank is neither the cheapest nor the most powerful around. However, it does come with a couple of features that make it a rather enticing option. It outputs a number of voltages (12V, 16V, 19V and 20V), automatically choosing the right one depending on the device which is connected.

This portable laptop battery charger also features two USB ports, and they’re hardwired to output 5V. You’re also supplied with 12 different charge tips, but if you have an Ultrabook that needs a USB Type-C port for charging, you’ll be out of luck. It also features a premium brushed aluminum finish, with bright blue LED status lights that clearly indicate the amount of juice left, or how close the battery is to full charge.

• This product is only available in the UK and Australia at the time of this writing. US readers, check out a fine alternative in the MaxOak K2.

Capacity: 27Ah Outputs: 1 x USB Type-C, 2 x USB Type-A, DC-out Notebook Connectors: 0

If you are looking for a versatile laptop charger, then do consider this RavPower offering. It is by far the most expensive model on our list, but this Reddot award winner carries a feature that no one has replicated till now. It has an AC output that can deliver up to 100W of power – yes, this could even power a TV if needed.

Note that you will probably need an adaptor (there’s one bundled) because the power bank can only accommodate two-prong plugs. You will be able to take it on a commercial flight, but you will not be able to recharge it via USB.

10. Dell Power Companion PW7015L

Great if you have a new Dell laptop

Capacity: 18Ah Outputs: 2 x USB Type-A, DC-out Notebook Connectors: 0

Dell sells the Power Companion with various battery capacities. It is more compact than the RAVPower models, and the unit looks like a Dell power brick that charges your laptop. When you're at your desk, you can daisy-chain to recharge the Power Companion and your Dell laptop by connecting your Dell charging brick to the Power Companion, and then connecting it to your notebook.

Dell's Power Companion is a far sleeker battery pack if your office relies on Dell Inspiron, Latitude, XPS or Venue laptops and tablets, with the added benefit that it has extra USB ports should you need them.
