Best Portable Power Bank In 2021 – Top 10 Rated Reviews


1 BONAI 5.6A 4-port 30,000mAh Portable Charger- Mint – Best 30000mAh Portable Power Bank

The Bonai portable charger is a slim handheld power bank with good looks and a couple of surprises. A colorful metal body protects the bank from damage and dust, so it is sturdy enough to be used for light outdoor activities. The unit comes with a built-in LED flashlight to help you roam around in the dark or in emergencies.

The Bonai isn’t just built to charge your devices; it will protect them as well. It uses circuitry that prevents overcharging, current fluctuations, and overheating. So, you can relax, knowing your device will not get damaged.

The four ports…

The Bonai has a capacity of 30,000 mAh, which is impressive for its size, and four USB-A ports. The total power output of all the ports is 5.6A, while each port can charge to a maximum of 2.8A. This means that the maximum charging speed is limited to two devices, and more connections will slow it down.

Loading it with power…

Recharging the power bank to full capacity takes about a full day; you simply use the provided 2.0A Max lightning cable and your own wall or car charger adapter. If you need it sooner, the Bonai has a second IN port that will allow you to add an additional 2.0 Max lightning cable, cutting the charging time in half.

Specifications:

  • Dimensions: 6.9 x 3.3 x 1 inches
  • Outputs: USB-A
  • Connector Type: Lightning cable 2.0 Max

2 HALO Bolt Portable Charger 58830mWh with AC Outlet; Phone/Car Battery Charger – Best Portable Power Bank for Charging Car Battery

The HALO Bolt is a great portable charger, but maybe not for taking to your favorite coffee shop and sitting with your computer all day. The Bolt is listed with 58,830mWh, which roughly translates to 16,000mAh, give or take. That might get you about 45 minutes of use on a power-hungry laptop.

Having two USB-A ports and a three prong AC outlet, the HALO is a very capable charger and can charge multiple items at a time. Though, that still isn’t what makes the HALO shine.

It does what?

Going on a road trip in your car or on your motorcycle, using an ATV to get around on the trails, or spending the day on the lake in your boat, this is where the Halo stands out.

The Halo Bolt is intended to be stored in an emergency kit for your vehicles, so it is small and can fit in almost any storage compartment or area. It comes complete with an LED floodlight on the side and a DC port with removable jumper cables for your vehicle’s battery.

Safe and secure…

Safety mechanisms are in place, so the jumper cables don’t spark, and they will not work if put on the battery in the wrong way. Indicator lights will let you know that everything is in proper order and safe to use.

The HALO Bolt recharges using a provided standard AC wall charger. Other provided items are jumper cables and a convenient carry case to keep everything in one place.

Specifications:

  • Dimensions: 1.6” x 3.8” x 7.2”
  • Outputs: Two USB-A, Three pronged AC, DC jump starter

The RAVPower is more than a phone charger, as it is equipped with a three prong 80W AC power outlet that you can plug your computer or other devices into. Please note that the AC outlet is not compatible with the Apple or Huawei original charging blocks. It is suggested to use the USB-C port and cable to charge those computers.

More capabilities…

The large 20,000mAh battery capacity can charge many of your devices several times before needing to be powered back up. Blue light indicators will let you know the power status, so there are no surprises or mishaps.

Equipped with a USB-C input/output 30W PD (power delivery) 3.0 port and USB-A 18W QC (quick charge) 3.0 port, the RAVPower is able to charge most devices quickly. The USB-C port charges up to two and a half times faster and can save up to 60% of standard charging time.

What’s included…

There is also a super bright LED flashlight for emergencies or use during a blackout. It is essential that the DC out port and the car lighter port not be used at the same time, as it could damage the power bank. However, it is safe to use the USB ports while using one of the other ports.

Safety first…

The power bank uses a BMS (battery management system) with features to prevent overcharging, overheating, over-voltage, and short-circuiting to protect your devices. The unit will automatically shut down when the maximum of 150W is being pulled. You can simply unplug the devices and put in the power source adaptor to reset the power bank.

Best Portable Power Bank Buyer’s Guide

There are vast arrays of portable power banks available that are capable of a variety of different tasks. As they range from merely charging a phone to being able to jump-start a car battery or running a CPAP machine, it is essential for you to know how you will be using it.

Let’s cover some of the more important aspects of what you should be aware of and what to look out for…

Types Of Ports

EC Technology Portable Charger 22400mAh Power Bank Ultra High Capacity 3 USB Charging External Cell Phone Battery Pack with Auto IC and Flashlight

Before buying a power bank model, you need to understand the devices that you will be connecting to them. Many devices have a basic USB-A port and can be connected without a problem. Most computers and some phones and tablets may require the use of a USB-C port to suit their power demand.

Other devices may require an AC outlet or other type of port. With all of these, it is important that you also have the correct type of cord to fit and work properly in the ports.

Power Ratings

Most ratings for portable power banks are stated in mAh (milliamps per hour); some will be stated as mWh (milli-Watts per hour), be careful here. Milli-Watts will show a much higher number compared to milli-Amps, and you may not be getting what you think.

A general rule of thumb without using an exact formula is to consider that around 35% of the mWh will be an approximation of mAh.

Then there is device voltage to consider…

Many manufacturers might simply list the capacity of the battery cell as an advertisement. For example, 28,000 mAh, doesn’t necessarily reflect the actual charging power available for a device, as that is dependent on volts. A truer representation would be 28,000mAh @ 5V. You could read this as; a phone @5V with a 4,000mAh battery would get seven full recharges of its battery.

It is crucial to have a good idea about the mAh and Volts when it comes to recharging computers. This is because some portable power banks will offer an AC outlet that may or may not be compatible with your laptop’s power block; always be sure to check. Some may offer a DC out port or USB-C port to charge your computer.

Understanding the Volts and mAh will give you a good idea of how well the power bank will work charging your computer and other devices.

A Final Note

As power banks are truly varied, you might consider getting more than one to cover a spectrum of needs. If you are looking to charge devices, such as computers, that demand a lot of power, you will want to purchase a charger that is 20,000mAh or more.

You will either have to have or purchase a charging block separately, as most power banks only provide the correct type of charging cable when purchased.

So, What Is The Best Portable Power Bank?

However, our recommendation of the best portable powerbank is the…
