The DWYM Expert Take

The best thing about the ZMI USB PD Backup Battery is that it supports all of the latest fast-charging protocols, including USB PD 2.0, QC 3.0 and BC 1.2. It also has the power to charge items besides smartphones and tablets, taking on your MacBook or Nintendo Switch console with ease. It does weigh a little more than other portable chargers, but you get three charging ports, with one serving as either an input or output.

Although the 20,000 mAh capacity of PowerPack 20000 is impressive, it’s certainly not the first portable battery to pack in that capacity. However, PowerPack 20000 distinguishes itself from many others by offering support for all of the standard fast charge...

The PowerPack 20000 includes a USB-C power cable that handled charging the MacBook and recharging the internal battery pack.

The ZMI QB820 is a great, large capacity USB-C PD power bank for the Nintendo Switch. It’ll charge the Switch at the fastest possible rate in handheld mode, equal to any wall charger.
- Switch Chargers
What makes using this power bank even better is that it actually goes beyond charging with its two USB-A ports and that’s because once you connect the USB-C port to a laptop, you can use it as a USB Hub.
- Charger Harbor
Looks clearly mean nothing when it comes to a product like this, so in terms of this charger’s abilities to keep your devices charged, it too excels in this era. It features three total USB ports with two of them...

The battery doesn’t come with an adapter, which is a mark against it not on cost, but because it can be tricky to find a good adapter that matches the PowerPack 20000’s wattage.

My only gripe is the size and weight, but it is no bigger or heavier than any other power bank of similar capacity.
- Switch Chargers
It's quite large and heavy and not really meant for holding and charging your devices.

The DWYM Expert Take

For portability, you can't go wrong with the Anker PowerCore+ Mini Portable Charger, which is slightly larger than a tube of lipstick. Its size makes it easy to slip into a pocket so that you can charge on the go. However, there are some sacrifices with this model, including the ability to only charge one device at a time.

What other experts liked
Fantastic price, very portable, and has decent battery.
- BestReviews
The mini charger is super small and compact.
- Runner Click
However, it does have one if the longer warranty periods of the group that offers limited coverage over 18 months.
- Tech Gear Lab
This is about as light as they come too, making it great to place in any carry-on or backpack. The build quality is excellent with a very compact interior design too.
- Land Of The Traveler

The power bank is 3.5 inches long and about .9 inch thick with a width of .9 inches – almost the same size as a lipstick.
- Power Bank Guide
We love that it intelligently charges your device as fast as your device allows which is great because overcharging or rapid charging batteries can seriously shorten their lifespan.
- Trek Bible
October 26, 2018 | Full review
The size of the power bank is so small that it can even fit easily in any pocket and this means that you can very well put the Mini and your phone into the same pocket and have your phone being charged as you walk the streets.
- Charger Harbor
In saying this, the Anker PowerCore mini portable charger looks pretty smart and manages to avoid that “tacky” look that some competitors have.

The design itself is very minimalistic and elegant. I already mentioned about aluminum shell finish which feels very solid in your hand and gives you extra peace of mind if you accidentally drop it.
- XDA Developers

It has a small capacity for an external battery at 3350mAh which keeps the size to a minimum – it’s about the same size as a tube of lipstick.
- Deteched
There’s been multiple times where I forgot I had the mini portable charger in my pocket. Being the size of a stick of lipstick, it’s ultraportable and ultralight.
- Charge Champ

What other experts didn't like
It charges devices slowly.
- BestReviews
Lacks an indicator to display leftover battery life.
- Runner Click
It doesn't have a built-in flashlight and also lacks integrated cables or a charging plug, requiring you to use your own USB wall brick.
- Tech Gear Lab
Additionally, the efficiency can tend to decrease over time. This is common for all battery packs but since you are dealing with just 1 charge it could be a factor if you intend to use it very often.
- Land Of The Traveler
January 2, 2019 | Full review
However, 3350 mAh battery pack capacity is not adequate for most tablets and the latest generation of Android phones that have 3000 or 4000 mah batteries.
- Power Bank Guide
The charging speed of the PowerCore+ Mini is 5V/1.0A and that’s not exactly a fast charging speed.
- Charger Harbor
In most cases however, you are dealing with sub standard cells and are going to have a bad time after a few charges of any device.
- Power Bank Expert
August 17, 2016 | Full review
To display the charging capacity, led has 3 colors to indicate: green 50%-100%, yellow 20%-50%, and red 5%-20%. Its obviously not as accurate as Astro.
- XDA Developers
May 29, 2015 | Full review
It takes roughly three hours to recharge and can output power at one amp. One amp certainly isn’t quick by today’s fast charging standards, but it is a trade-off I’ll take in place of better energy efficiency.
- Deteched
I do wish they could have put multiple lights as a more accurate way of finding out how much charge is left.

An Overview On Portable Chargers

There’s no shortage of portable chargers available. In fact, once you start shopping, you’ll likely immediately be aware of the vast array of products out there. But although portable chargers may look alike, some even promising very similar specifications, there are notable differences from one product to the next.

One of the biggest features to look at when shopping for a portable charger is how long it will take to charge your devices. This is especially important if you have a device with fast-charging capabilities since not all portable chargers support that. A device that can fully charge multiple items at once in a limited amount of time may be well worth paying extra or sacrificing other features, such as portability.

Another feature that sets some newer chargers apart from others is the ability to charge more than just a smartphone or tablet. Some of these devices can charge a laptop or gaming console, making them useful if you’re regularly out and about with these items. You’ll also find some chargers can plug into your computer and act as a hub, charging multiple devices at once while you’re working.

While all portable chargers are designed to tuck into backpacks and laptop bags, some are even more powerful. If it’s important to be able to slip your charger into a pocket or handbag, look for much smaller devices. Some are only slightly larger than a tube of lipstick, making them especially portable, but you may sacrifice power and charging capabilities for that convenience.

While you’re waiting for your devices to charge, you may occasionally want to check in on status. Some chargers have indicator lights that show you exactly where you are in the process, giving you a general idea of the time you have left. However, if you’re only charging smartphones and laptops, you’ll likely be able to get this same information by looking at the device itself.

DWYM Fun Fact

USB-C is poised to revolutionize the way devices are charged. Instead of having multiple ports on a device for all the different cables you need, with a USB-C, you can use the same port as both an input and an output. This can be seen on newer equipment like MacBooks. You can either plug your power cord or your USB charging cord into any of the ports provided, aside from the headphone jack, but even that is changing. Some phones replace the headphone jack with a USB-C port, although you’ll still find the traditional 3.5mm headphone jack on laptops. The goal with USB-C is not only to streamline the ports that devices need to have but also to provide a single standard that will make life easier for everyone.

The Portable Charger Buying Guide

  • A good portable charger starts with its power. The Anker PowerCore+ Portable Charger and Jackery Supercharge Portable Charger pack the biggest punches, with 26800mAh of power each. You’ll still get impressive power in the ZMI USB PD Backup Battery, which has 20000mAh capacity. The much smaller Anker PowerCore+ Mini Portable Charger lags behind, with only 3350mAh.
  • The time it takes to charge is a top consideration. Although this can vary depending on the capacity of each device you’re charging,  the Anker PowerCore+ Portable Charger generally excels at this, with the ability to charge three devices at once at a lightning-fast speed.
  • Before you can charge other items, you’ll need to charge the portable charging device. The Anker PowerCore+ Portable Charger can charge faster than other power banks, reaching full capacity in about 6.5 hours. The Anker PowerCore+ Mini Portable Charger also falls behind in this area, taking approximately three hours to fully recharge after depletion.
  • One factor determining how quickly your portable charger can get results is whether or not it supports the new fast-charging capabilities built into many modern devices. The ZMI USB PD Backup Battery stands out from the pack here, supporting all the current protocols, including USB PD 2.0, QC 3.0 and BC 1.2. The Anker PowerCore+ Portable Charger can’t compete in this area, lacking the ability to charge devices like the iPhone X or iPhone 8 at the fastest available speed.
  • New charging technologies built into devices like laptops and gaming consoles make it easier to build portable chargers for them. The ZMI USB PD Backup Battery can not only charge your smartphone but it also capably charges the newer MacBooks that have Thunderbolt ports, as well as being able to charge the Nintendo Switch at the fastest possible rate in handheld mode. The Jackery Supercharge Portable Charger can also charge both MacBooks and Nintendo Switch consoles. The Anker PowerCore+ Mini Portable Charger is very limited in what it can charge, lacking the power necessary to handle most tablets. You’ll also find it can’t charge the latest Android phones, which have higher-capacity batteries.
  • One of the best things about the ZMI USB PD Backup Battery is its ability to serve as a hub. Simply plug it into a computer’s USB-C port, then plug your items into the two USB-A ports to charge while you work.
  • If you’re concerned about portability, look closely at the weight and size of the devices you’re considering. The Anker PowerCore+ Mini Portable Charger is among the lightest portable chargers you’ll find, weighing only 2.8 ounces. Compare this to the 15.16 ounces you’ll get with the Jackery Supercharge Portable Charger, and you can see the difference. Both the ZMI USB PD Backup Battery and Anker PowerCore+ Portable Charger are on the higher end of weight, at 14.25 and 13.5 ounces respectively.
  • The Anker PowerCore+ Mini Portable Charger is also far easier to slip into a pocket, measuring only 3.5 inches long and 0.9 inches thick. The ZMI USB PD Backup Battery, Anker PowerCore+ Portable Charger and Jackery Supercharge Portable Charger all have longer, slimmer profiles, similar in shape to a smartphone. They each measure around 6 inches by 3 inches, meaning they’ll still easily slip into a laptop bag or purse, but they may not be quite as easy to carry around all day with you.
  • Portability comes at a price, however. With the Anker PowerCore+ Mini Portable Charger, you can charge only one device at a time. The Anker PowerCore+ Portable Charger, on the other hand, has three powerful output ports. With the ZMI USB PD Backup Battery, you also get three charging ports. That includes a USB-C input and output port, which means you can either use it to charge a device or accept a charge. The Jackery Supercharge Portable Charger has only two ports, a USB-C and a USB-A.
