Anker PowerCore Fusion 5000 Review - mybest

While the Anker's PowerCore Fusion 5000 gets a lot of rave reviews for its convenience and ease-of-use, it also has its fair share of negative reviews online that mention slow charging speeds or defective products that refuse to charge. This may spook some potential buyers from considering it altogether.

To put both good and bad reviews to the test, our editing department purchased an Anker PowerCore Fusion 5000 and subjected it to rigorous testing to see if it's worth the cash. If you're considering purchasing the Anker PowerCure Fusion 5000, then read on.

What Makes the Anker PowerCore Fusion 5000 so Popular?

The Anker PowerCore Fusion 5000 is a unique fusion of a power bank and USB wall charger, combining the functionality of 2 devices in one package.

The device comes with foldable prongs that allow it to charge directly from a wall socket, making charging easy and convenient. This allows users to declutter as it eliminates the need to pack extra charging cables, which also makes it a must-have for long trips.

While it's internal battery capacity of 5000mAh leaves a little more to be desired, it comes in handy during emergencies since it packs enough energy to fully charge a smartphone.

How to Use Anker PowerCore Fusion 5000

Using the Anker PowerCore Fusion 5000 is as simple as connecting your smartphone using the included USB cable. The included micro USB cable is compatible with Android smartphones. Note, however, that iPhone charging cables must be purchased separately as they are not included in the box.

When used as a wall charger, it prioritizes charging any smartphones that are connected to it before charging its own internal battery pack. Users can charge the internal battery simply by plugging the device directly into a wall socket. Its LED indicators show the amount of available power during charging and when in use as a power bank.

The Anker PowerCore Fusion 5000 comes with 2 micro USB cables, a travel pouch, and a user manual. The travel pouch is made of stretchable nylon fabric with a high-quality feel to it. The user manual can be also downloaded directly from Anker's website, making it easier to access and reference when needed.

Looking into the Anker PowerCore Fusion 5000's Reviews

The Anker PowerCore Fusion 5000 has plenty of good reviews online. Users have cited its ease of use and convenience, praising it as a must-have item for extended trips and other excursions.

However, it also has its fair share of critical reviews. Here are some of the most common critical reviews we've seen online.

Charging Woes: My Phone Won't Charge!

The most common issues mentioned in the critical reviews we've seen online involved the device's apparent lack of charging capabilities.

Despite claiming to have ample battery capacity and fast-charging capability, users have complained of slow charging speeds or being unable to charge their phones altogether.

It doesn't charge at all. It looks like the internal battery is charged, but it doesn't respond at all when I connect my phone and press the button.
Charging speed is incredibly slow.

Portability Issues: it's Too Heavy!

Some of the comments we've seen did not cast its portability in a positive light. Most people purchase power banks as a way to charge their devices on the go, so weight and portability are important. Which is fair, as its wall-charging capabilities are negated if it's too heavy to carry around.

Its wall charger capabilities are very appealing, but it's too heavy to carry around.
When I plug it in and use it as a wall charger, it feels like it will fall right out of the socket due to its own weight.

Battery Problems: it Runs out Too Fast

While comparatively less in number, some of the critical reviews also touch on the internal battery's capacity. The Anker PowerCore Fusion 5000 has an internal battery capacity of 5000mAh, which is admittedly less robust than other offerings on the market.

I think its capacity is too limited for it to be a viable power bank.

Putting the Anker PowerCore Fusion 5000 to the Test

Now that we've touched on the reviews we've found for the product, it's time to put them to the test. We purchased an Anker PowerCore Fusion 5000 and asked a panel of electronics specialists to perform the following tests:

Test 1: Convenience

Test 2: Charging speed

Test 3: Actual charging capacity

Test 4: Heat generation

Test ① Convenience

Our first order of business was to test its convenience and ease of use.

While plenty of reviews online praise the Anker PowerCore Fusion 5000 for its ease of use, we also found some negative reviews concerning its weight. That's why we measured its weight to see if these reviews hold any water.

Weighs about 6.6 Ounces - Not Too Heavy to Carry around

Our weight test showed that the unit itself weighs a measly 6.6 ounces (or 186 grams). By comparison, a small can of coffee weighs approximately 6.7 ounces. This shouldn't feel too heavy when placed inside a bag.

Some negative comments mentioned that the unit is so heavy, it feels like it would fall out of the socket under its own weight. While it didn't actually fall off the socket during our tests, suffice it to say that we completely understand where these reviews are coming from.

2 Charging Ports Make it Super Convenient

The device comes with 2 charging ports, allowing users to charge 2 USB devices simultaneously. This makes it perfect for people that find themselves needing to charge multiple electronics on the go. Anker's unique technology gives the device a wide range of compatibility and allows it to charge most devices at full speed.

Test ② Charging Speed

Next, we took a look at charging speeds.

While the Anker PowerCore Fusion 5000 supports high-speed charging via QuickCharge, a significant portion of reviews online feel that its charging speeds are not up to the task. To put these reviews to the test, we measured its charging speed using special equipment.

Average Charging Current of 1.40A, so it's Not Super Fast

When we hooked the device up to a digital power meter, we found its power output to be at 1.40A, which is a little higher than average. In comparison, most power banks have an output current between 0.96A and 1.31A, which in turn negatively impacts charging speed. This means that the Anker PowerCore Fusion 5000 actually has a higher-than-average current output and charging speed.

We also tested its charging speed as a wall charger plugging the unit directly into a wall socket, connecting a fully-drained smartphone to it, and measuring the time it took to fully charge the phone. 

In our tests, we found that it took 2 hours and 30 minutes for it to fully charge the phone. Considering the fact that the internal battery has enough capacity to fully charge a smartphone, we consider its charging speed to be reasonably quick.

Test ③ Actual Charging Capacity

Our next agenda was testing its actual charging capacity.

To test this, we connected a USB fan to a fully-charged unit and let it run continuously until the battery ran out while using a current measurement device to test the battery's actual capacity. This allowed us to find out exactly how much charge the battery pack can store.

Charging Capacity is 2963mAh - Enough to Completely Charge 1 Smartphone

Our testing indicated that the Anker PowerCore Fusion 5000's charging capacity is around 2963mAh, which is 60% of its advertised capacity of 5000 mAh.

This is normal as power banks usually undergo some form of conversion loss, leading to actual capacities of around 60% to 70% of their advertised capacities. Considering that 2963 mAh is just enough to charge a smartphone once over, the battery capacity may not be enough for buyers who need to charge their devices multiple times in the course of a day.

Test ④ Heat Generation

Lastly, we tested the amount of heat generated by the device.

Some power banks generate heat when used. Our use tests also tested the Anker PowerCore Fusion 5000 for any safety issues related to heat generation.

No Significant Heat Generation; PSE-certified Device for Peace of Mind

We used the Anker PowerCore Fusion 5000 both as a wall charger and power bank during our tests, and we are glad to report that it did not generate any heat in both use cases. While it did generate a small amount of heat when used for prolonged periods of time, it did not generate enough heat for it to become too hot to the touch.

The Anker PowerCore Fusion 5000 has been found to comply with the Japanese Act on Product Safety of Electrical Appliances and Materials by the Japanese Ministry of Economy, Trade and Industry, and awarded with PSE certification.

The Final Verdict: a Very Convenient Charger for Long Trips or Excursions

We were reasonably impressed by the Anker PowerCore Fusion 5000 as a power bank. Its most unique feature is most definitely its built-in wall charger capabilities, which greatly extend the capacity of its built-in batteries (providing there's an outlet). This makes it perfect for office or home use.

Its 2 USB ports mean that you can charge multiple devices such as your phone and iPad at the same time, making it extremely convenient and easy to use. While its capacity and charging speed are on the average side, neither of these were pain points for us during normal use. 

Taking build quality, size, and weight into consideration we highly recommend the Anker PowerCore Fusion 5000 for people who value portability and want to pack light. And at its price point of $29.99, it's a great buy for people who value convenience, price, and ease of use.

The Anker PowerCore Fusion 5000 Comes in 3 Colors!

The Anker PowerCore Fusion 5000 comes in 3 colors: black, white, and red. Most power banks usually come in either black or white, so the added color option might be just what you're looking for if you want a power bank with a more personalized touch.


In this review, we took a look at the Anker PowerCore Fusion 5000 and subjected it to a battery of rigid testing. Its affordable price point, convenience, size, and charging capacity make it an excellent product for buyers looking for a power bank that is both compact and portable.
