We’ve already reviewed two of MAXOAK’s most famous power banks with their 50,000mAh and 30,000mAh portable chargers having not only high power capacities but also being able to charge lots of devices at once.

With that said, this power bank from MAXOAK takes a more simple approach because it has a 13,000mAh power capacity with just two charging ports. So let’s see if a more simple approach with a power bank is what MAXOAK is good at, or if they should just stick with creating large behemoth portables chargers.

Take a closer look at this 13,000mAh MAXOAK power bank in this Charger Harbor review.

Power Capacity:

How much power you’ll be getting

The power capacity starts at 13,000mAh and you’re going to end up receiving quite a normal Output power capacity through the conversion process during charging. The conversion is 70% efficient and that’s going to result in about 9,000mAh of power capacity that you can use with the devices that you change.

Charging Smartphones

With that said, this MAXOAK power bank is going to be most useful to charge smartphones with, because you’ll be able to charge most smartphones multiples times.

A smartphone with a large battery capacity like an iPhone 6 Plus with its 2,915mAh battery will be able to charge 3 times to its full charge. The same things are true for a Galaxy S7 with its 3,000mAh capacity that will also be able to charge to full power about 3 times.

So if you have a smartphone that has a smaller battery capacity than either an iPhone 6 Plus or Galaxy S7 you can expect to get as much as 3 full charges and most likely even more.

Charging Mini tablets with the MAXOAK 13,000mAh Power Bank

Charging tablets with the MAXOAK power bank can be done too, but it’s best to charge Mini tablets like the iPad Mini 2, 4, and Galaxy Tab series. If you’re charging either an iPad Mini 2 or 4 then you’ll be able to get a single full charge and then possibly another halfway charge.

Charging a Galaxy Tab with their 4,000mAh power capacity will result in 2 Full possible charges.

Charging Full-Sized Tablets

If you’re charging Full-Sized tablets like an iPad 12-Inch, then you’ll get quite close to its full power because a Full-Sized iPad has a power capacity of 10,000mAh and so it’ll get to about 90% of its power.

Output Charging:

Output charging is good but it could be better.

We say this because one charging port delivers a charging speed of 5V/2.1A and that’s good. The other charging port Outputs 5V/1.0A, which isn’t good because that’s a slow charging speed for a lot of devices.

So if you’re only charging a single device with this power bank, you should always use the 2.1 Amp port because that’s going to provide a faster charging speed.

Only use the 1 Amp port if you’re charging two devices at once. With that said, at least each of the charging ports can use their max power because the Max Output of the power bank is 5V/3.1A.

Input Charging:

The MAXOAK power bank has a recharge rate of 5V/1.5A and as long as you’re using a 2 Amp wall charger it’ll be able to charge to its full power within 8-9 hours.

Design

Size and Weight:

Not too large of a power bank but the weight can feel a bit heavy if you’re holding it for long durations of time. MAXOAK mentions that you can fit it into your pocket but we find that to be a joke. It’s best held in the hands.

It has a length of 4.7 inches, a width of 2.8 inches, and a thickness of 0.8 inches. The weight of the power bank is 10.7 ounces.

Functional Components:

The 2 USB Output ports are on a single side and there’s a Micro-USB Input port on there too. On the long side of the power bank is where there’s the power button.

On top of the power bank is an LCD power capacity display that shows the power capacity in a percentage manner. With that said, it’s important to know that the LCD only shows two digits, and so when the power bank shows “99” when it’s recharging, that means it’s full.

Charging automatically starts, however, there have been cases that when a device is connected, the power bank doesn’t detect it; then you have to press the power button to begin charging.

Build

Structure and Material:

The siding of the power bank is made of Aluminum and the centerpiece is made of plastic. It has quite a strong build, and even though it’s no rugged power bank, we think that it can do well with a drop to a softly covered flooring.

Tech:

On the tech side, the MAXOAK power bank doesn’t do anything too special. Since it doesn’t use any special batteries, the conversion rate of the power bank is average, but it does use safety tech to keep you and your devices safe during charging.

Reliability

The MAXOAK 13,000mAh power bank is quite reliable because even after conversion, the power capacity is still quite solid that you can charge some devices multiple times over.

Charging speeds could be better, or rather the Charging design could be better because you can’t charge 2 devices at very fast charging speeds at the same time since one port only offers 1 Amp of charging speed.

Even though it won’t fit into your pocket, the 13,000mAh power bank is still reliable to take anywhere you want.

Summary:

Power:

The power capacity holds up well, and you’ll be able to charge smartphones multiple times even if they have large power capacities. Charging speeds shouldn’t be set to individual charging ports because in this case, one port will deliver slow charging only.

Design:

Not the lightest or the thinnest but this 13,000mAh power bank holds up with a short length that makes it easy to hold in a single hand. The use of an LCD power capacity display is very helpful.

Build:

On the physical side, it’s a surprisingly strong power bank.

Reliability:

We think that it holds up quite well as a portable power bank that you can rely on for those times when you need charging in an emergency.

Conclusion:

So this MAXOAK 13,000mAh power bank isn’t nearly as impressive as MAXOAK’s 50,0000mAh and 30,000mAh power banks. Although it does well enough to get the job done. The power capacity is still enough after conversion and you can still charge two devices; albeit, the charging design could use some work.

We highly recommend this power bank for getting the basics down very well, and the use of an LCD power capacity display is more helpful than a few dots to tell the power capacity.
