Best Power Bank Consumer Reports

Consumer Reports on #1 Power Bank

Consumer Review:

I’ve had this charger for six hours since it was delivered and only four of those are lit. I am not impressed with Anker, but after some time working on the device to figure out how best use my resources (power outlet), now that all of its settings have been configured correctly–this thing rocks! Five stars from me 🙂

Consumer Review:

I love that this power bank is sleek and sexy. The tiny texture provides a nice feeling holding it, but what really sells me are the two ports! I can charge my phone as well or use one of them for another device by plugging into USB-C cable (or even just an old fashioned charger). It accepts standardised charging methods so you don’t have to worry about compatibility issues like with other brands’ products; plus there’s no risk in buying an older model when newer ones come out every year – these hold their value better than gold too!

Consumer Review:

This power bank is the best! I love that it can charge two things at once, and its charging speed is really impressive. The coolest part? It knows which device needs to be charged faster based off of their size or how often they are used – my phone was always dead when we were out running errands because normally there’s not enough time for me to do all these activities while also listening in on your conversation about why ____ doesn’t work like he promised so clearly you need a new marketing team 😉


Frequently Asked Questions

Which power bank is better 10000mAh or 20000mAh?

The difference between 10000mAh and 20000mAh is not that significant, but it’s still worth considering. When your phone reaches 0% battery, the power bank will only provide up to 50% extra running time before it too hits zero. If you really need more power then you should probably go for a higher-capacity charger with a higher milliampere-hour rating (mAh).

What is the most reliable power bank?

The most reliable power bank is the one that will charge when you need it to, when you want it to.

The important thing is finding a charger with high milliamp hours (mAh) for the device in question, so they the power bank can work in cases of emergencies or urgent conditions. Most smartphones can go between 12-24 hours before they need charged again so prioritize accordingly.

Which portable power bank is best?

This is a difficult question to answer because it really depends on your personal circumstances, preferences and needs.

How do I choose a good power bank?

I’d recommend getting one that lets you customize the power capacity. A power bank is basically a portable battery, storing your phone’s energy when it has to work harder or can’t reach an outlet.

Different phones have different specs, so not all batteries will fit in all devices. Make sure to check out the milliamp hours before purchase so you know how much you need for your device in particular!

How do I choose a portable power bank?

Vendors like Anker and Aukey might advertise that their battery packs will support most major devices, but small details in the fine print — such as your phone’s model number — can render those promises useless. Consider seeking out a product with an adjustable output so you’ll never be stuck without power again.

How many mAh is a good power bank?

It depends on the power capacity of your device as well as how you intend to use it. Power banks can vary from as small as 7,000 mAh to as large as 100,000 mAh.

A portable battery needs a certain amount of power for a fixed time frame in order to be useful.

What is a good size for a power bank?

The size of the power bank you should be looking at is related to the number of milliamps (mAh) your device will use for a certain amount of time. The important part is calculating how long it will take for that many milliamps to be drained and choosing a power bank in relation to that information.

Generally, you can estimate

An android phone: 3000-5000 mAh

A tablet: 6000-12000 mAh

A mp3 player: 1000-2000 mAh

How do I choose a fast charge power bank?

It’s important to take time to know your device before purchasing a charger, but with most newer smartphones like the iPhone 8 and Samsung Galaxy S8, you needn’t worry about compatibility.

Most of them identify themselves when they charge up by notifying you of how fast they are charging when connected.

You want it to be at least 10 watts per hour if possible, with Quick Charge 3.0 being even better than that.

If you’ve got an older Android device or your model isn’t one that advertises its charging speed in these terms, look for something over 5 watts per hour with at least 25 million mAh capacities in order to avoid lag times between fully charged and half discharged.

Buying Guide

Capacity: Go for one that has almost the double the battery capacity of your phone

In order to charge your devices, you need a power bank. There are two things that should be considered when buying one: capacity and output voltage compatibility with different device types (e-cig batteries usually only work charging with 4V).

A bigger mAh will result in faster charges but make sure they’re compatible or else it may not work! It can get confusing trying figure out what kind of charger suits what kinds of electronics so check beforehand–you don’t want anything too low because then nothing would charge up anyway.

Quality and safety options: Look for build quality

What’s the best power bank for your phone? Size, portability and weight are all important factors. You want a light-weight charger that can easily fit into any bag without weighing down on you or getting in the way of what else is inside!

The downside to this type if product though might be its limited capacity (if it’s larger than 2200mAh).

To make sure that the device is charged properly and does not get damaged, a high-quality power bank should always be used.

A low quality Power Bank can damage your device by charging improperly or even explode!

Connectivity options and USB charging: The more the better

Most power banks have a variety of connectors and various voltages. This means they can charge multiple devices at once, such as smartphones or tablets for example!

If you want to charge multiple gadgets at once, then a power bank is what we recommend. There are two different types of connector on these devices: one for smartphones and another type that can be used by other electronic items such as video games or speakers with an input voltage ranging from 8-36 volts. Alongside having extra plugs available so users don’t have trouble finding their own charging cable when they need it most; some brands also include USB cables built right into the exterior which saves time searching around inside your purse/bag!

LED indicators: Go for them

All power banks are not created equal. Make sure to purchase one with clear LED indicator lights so you know how much juice is left and when your phone will be charged!

Brand name: Better to go for established brands

It is a good idea to buy from established brands when purchasing power banks. This way you are sure that your purchase contains all of the necessary components and circuits needed for use in portable devices, such as batteries or charging systems.

There is a reason why many people who want to buy power banks will go with the brands that provide high capacity at low prices. It’s because these types of devices can store your expensive gadgets and make them last longer when you’re on-the-go!

Safety: Go for power bank with a high grade Lithium-Polymer battery

Do you charge your mobile device at night? If so, be aware that it could cause problems. Some low-quality power banks fitted with exploding cells are capable of damaging not only a phone but also have serious consequences for users themselves!

It is important to go for a high-grade power bank as they will have improved safety features. They are also more reliable than regular ones because of their stable elements which reduce the chances of any explosions happening and keep your device safe in case something does happen, like an explosion or short circuit protection built into these Power Banks! It might cost you some extra bucks but we think its worth investing since this kind device protects not only yourself with its built-in protections against overcharging/heating etc., but others around you too by preventing fires caused due happened while charging items from certain brands (enough about Samsung).

Ampere count: Get it right

Understanding the ampere count of a power bank is important. It tells you how much electricity will be flowing from your charger to charge whatever device it’s connected with, and knowing this can save you money in unnecessary cost charges for excess energy used by devices that don’t need recharging as quickly or at all!

A power source should be able to supply the necessary current for any device. If a gadget needs 2 amps, then its voltage and amperage requirements are going to match up with an amp or two more than what is coming out of it!

A common question consumers have when they buy products online is “What kind of batteries does my item require?” Understanding how much battery life you can expect from various devices may seem daunting at first glance since there’s no way for shoppers know what their personal usage patterns will look like once everything gets hooked up inside your home.


The quality of cable matters too! As you can see, a cheap or low-quality charger could damage your device. Along with this it’s also possible that these cables will overheat and cause fire if they’re not tightly wrapped around the power bank itself

A good charging cable is worth its weight in gold because not only does it protect from surges but also keeps our devices charged quickly so we don’t have to wait hours on end for one little bit more juice – even when ours isn’t dead yet!

Don’t forget to charge your battery pack too!

The most important thing when it comes time for a power nap is that you have enough juice in the tank. You don’t want this precious resource drained before its got all but depleted, so make sure there’s cable included with whichever charger will be going on duty as well as an extra micro USB lead if needed (or ones of those adaptors). is supported by its audience.
