But with so many power bank options on the market, how do you know which one offers the most power and best value for your needs?

In this article, we will compare some of the top power banks across various factors like capacity, size, portability, and price to determine which is the overall strongest power bank available. Key factors we will consider include:

  • Battery capacity – The higher the mAh, the more charges it can provide
  • Size and weight – A balance of portable but still high capacity
  • Number of ports – More ports allow simultaneously charging multiple devices
  • Charging speed – Faster charging of your devices
  • Extra features – Indicators, built-in cables, wireless charging, etc
  • Price – The value you get for the price
  • Brand reputation – Established brands provide better quality assurance

Knowing how to evaluate power banks on these aspects will help you choose the best model to suit your personal power needs.

Power Bank Capacity Comparison

The most important factor in a power bank is the capacity, stated in milliamp hours (mAh). The higher the mAh, the more charges it can provide for your devices before needing to be recharged itself. Here is a comparison of the battery capacity across some top power bank models:

Power Bank Battery Capacity
Anker PowerCore+ 26,800 mAh
RAVPower 27,000 mAh 27,000 mAh
EasyAcc Monster 20,000 mAh
Mi Power Bank 20,000 mAh
AUKEY 20,000 mAh 20,000 mAh

As you can see, the Anker PowerCore+ tops the list with a massive 26,800 mAh capacity, which can charge an iPhone over 10 times. The RAVPower and EasyAcc models also offer incredibly high capacities of 27,000 mAh and 20,000 mAh respectively. This makes them some of the most powerful power banks available based on battery size alone.

Quick Charging Capabilities

In addition to overall capacity, we also need to consider how fast these power banks can actually charge your devices. Many newer power banks offer quick charge output to rapidly charge your smartphones and tablets. Here are some of the quick charging tech specs for the top models:

Power Bank Quick Charging
Anker PowerCore+ PowerIQ, VoltageBoost
RAVPower 27,000 mAh iSmart 2.0
EasyAcc Monster Quick Charge 3.0
Mi Power Bank Two-way Quick Charge

The EasyAcc Monster with Quick Charge 3.0 and the Mi Power Bank with Two-way Quick Charge are great choices if you want fast charging capabilities. The Anker PowerCore+ and RAVPower models also have their own proprietary quick charging tech to deliver fast power to your devices. So all of these high capacity options can juice up your gadgets rapidly.

Size and Portability

While capacity is important, you also need to consider the physical size and weight of the power bank. After all, a power bank does you no good if it’s too bulky and heavy to conveniently carry with you everyday!

Here’s a comparison of size and weight stats for the top models:

Power Bank Dimensions Weight
Anker PowerCore+ 7.9 x 3.2 x 0.9 in. 1.0 lb
RAVPower 27,000 mAh 6.8 x 3.1 x 0.9 in. 1.1 lbs
EasyAcc Monster 8.1 x 5.0 x 1.3 in. 1.7 lbs
Mi Power Bank 6.6 x 3.2 x 0.8 in. 1.1 lbs

The Mi Power Bank stands out as the lightest and most compact, making it one of the most portable options while still offering a 20,000 mAh capacity. The Anker PowerCore+ is also impressively small and light given its market-leading 26,800 mAh battery. Both deliver great power density.

The RAVPower and EasyAcc models are larger and heavier due to their ultra high capacities. The EasyAcc in particular is fairly large and heavy compared to the competition. So portability is a sacrifice.

Number of Ports

The number of output ports on a power bank determines how many devices you can charge simultaneously. More ports give you added flexibility to power multiple smartphones, tablets, or even laptops at the same time from one power bank.

Here is a rundown of output ports for these high capacity models:

Power Bank Output Ports
Anker PowerCore+ 2 USB-A, 1 USB-C
RAVPower 27,000 mAh 1 USB-C, 1 USB-A
EasyAcc Monster 2 USB-A, 1 USB-C
Mi Power Bank 2 USB-A

The Anker PowerCore+ stands out with 3 total output ports. This gives you two USB-A ports for regular USB charging plus a USB-C port for newer USB-C devices.

The EasyAcc Monster matches the Anker with 2 USB-A ports and 1 USB-C port. The RAVPower and Mi models only have dual USB-A ports. Still, having two ports allows simultaneously charging two phones or devices which is handy.

Charging Speed

We’ve looked at quick charge capabilities, but the actual charging speed will depend on the output power ratings. Higher power output equals faster charging, stated in terms of:

  • Watts (W)
  • Amps (A)
  • Volts (V)

Here are the power output ratings for the top power bank models:

Power Bank Output Wattage
Anker PowerCore+ 30W USB-C, 15W USB-A
RAVPower 27,000 mAh 45W USB-C, 18W USB-A
EasyAcc Monster 18W USB-C, 12W USB-A
Mi Power Bank 18W

The RAVPower model provides the fastest maximum charging wattage through its USB-C port at 45W. This gives it power delivery capabilities to even charge laptops. The Anker PowerCore+ also provides a high 30W output through USB-C.

For regular USB-A ports, the RAVPower and Anker models again lead with 18W and 15W output respectively. They can charge tablets and power-hungry USB devices quicker than the EasyAcc and Mi power banks.

So both the Anker and RAVPower pack not only high capacity, but also market-leading power outputs to quickly juice up your devices.

Extra Features

Beyond just power, there are some extra features that help make these power banks more useful and user-friendly:

  • LED Indicators – Show the remaining battery level and charge status
  • Built-in Cables – Convenient charging cable stores in the power bank itself
  • Wireless Charging – Charges phones wirelessly without cables
  • Flashlight – Built in LED flashlight is useful in emergencies

Here are some of the extra features included for these models:

Power Bank Extra Features
Anker PowerCore+ LED Indicators, Flashlight
RAVPower 27,000 mAh LED Indicators
EasyAcc Monster LED Indicators, Built-in Cables
Mi Power Bank LED Indicators, Two-way Wireless Charging

The Mi Power Bank stands out with a very cool two-way wireless charging feature to wirelessly charge compatible phones and earbuds. The Anker model includes a useful built-in flashlight. And the EasyAcc power bank stores charging cables within the battery itself for convenience. These bonuses help give you the best overall user experience.

Price and Value

With power banks offering a wide range of capacities and features, price is an important factor to get the best value for money based on your needs. Let’s compare prices for these top models:

Power Bank Price
Anker PowerCore+ $99.99
RAVPower 27,000 mAh $89.99
