Aibocn Power Bank 10,000mAh External Battery Charger

Has 2 charging ports, with the 2.1A providing fast charging.

It's a really large power bank for its power capacity and charging capabilities. It should be smaller to today's standards.
You have to press the button to begin charging.
Charging speed is not shared between the charging ports.

Here at Charger Harbor, we’ve reviewed lots of 2-Port power banks (like GOAL ZERO YETI 1250 ) Some of these 2 port portable chargers end up being really good, and others are built on being mediocre. If there’s one thing that stands very true is that 2 port chargers are meant to deliver more than just what a 1 port power bank provides because having 2 charging ports means more than just being able to charge 2 devices at once. It means that it’s able to use better tech, higher power capacity, and faster charging. These kinds of power banks have more to prove on what they’re capable of.

This is the Aibocn 10,000mAh power bank, with its 2 charging ports, let’s see if it really provides value that it’s built for.

Power Capacity:

To start with, the initial power capacity is 10,000mAh and although that sounds good, the power bank doesn’t do so well with its conversion rate. Sure, an Output capacity is dependent on the charging speed and the efficiency of the battery that’s used with the power bank but in this case, there’s nothing special about the battery and the charging speeds aren’t going to impress unless you’re charging a tablet. With that said, the power bank can lose about 3,000mAh of power capacity through charging. However, that conversion rate can change depending on what you’re charging and how fast it’s charging.

With an Output power capacity of 7,000mAH that you’ll actually be getting, the charger does well to charge smartphones. This is because most smartphones will be able to charge 2 times or more. As for tablets, it’s not the best portable charger to use with a tablet unless you’re using it with tablets that have lower battery capacities like the iPad Mini 2 and 4 versions. So if you do want to charge a table with this power bank, then it’s best to use the entire power capacity and charge the tablet alone with the 2.1A port.

The best word to explain the charging speed of the power bank is saying that it’s very average. That’s right.

One of the charging ports is able to deliver a charging speed of 2.1 Amps, and that’s actually a really good charging speed because it’s very close to a Max standard charging speed of 2.4 Amps. The other port is 1.0 Amp, which is a much slower charging speed. The 2 charging ports come together to a Max Output of 3.1A, but there’s one major problem that is also prevalent within other power bank chargers. Charging speeds for each port is fixed, so the 2.1 Amps that comes from the 2.1A port can’t be transferred over to the other port.
Make Sure to Choose the 2.1A Port First

This is a problem because if you’re charging 2 smartphones, then one smartphone will be charging at its max speed with the 2.1A port, while the other is limited by the 1.0A port. But if the 2.1A port were to actually have an open circuit and share Amperage that it’s not using with the other port, then there would not be a compromise on what device gets faster charging and which gets slower charging because both charging ports would be of equal capabilities.

A 3.1A Max Output is nice to have but there’s really no point in having it when the charging ports are limited to what they can provide.
Input Charging: 5V/1.0A

The Input charging is a disappointment with the power bank only being able to recharge at a max rate of 5V/1.0A. Most power banks with its capacity, the recharge rate is usually 2 Amps and you can charge the power bank to full in 6-7 hours.

In this case, even if you use a 2 Amp wall charger, this power banks will recharge to full in about 11-12 hours. Aibocn should consider upping their input charging speed, simply because a 1 Amp Input is a thing of the past and people want to use their portable charger ASAP.

Size and Weight

For a 10,000mAh power bank, this charger is too big.

The length is 6.8 inches, it has a width of 4 inches and the thickness is 1.4 inches. So it’s a large power bank that is the same size of a 20,000mAh power bank. The weight is also quite heavy at 9.6 ounces. Overall, the size and weight don’t match up the power capacity of the charger. We understand that the power bank has two charging ports but with its capacity, it’s supposed to be smaller. Just look at the PowerCore 10000 from Anker; it has a power capacity of 10,000mAh and yet it can fit into a bag or even a pocket.

With its size and weight, it’s not really possible to comfortably use this power bank while you’re holding it. So it’s best to place it into a bag and use the charger by setting it down and charging your devices.

Functional Components

The functional parts of the charger are placed in the same general location. The USB charging Output ports are on a long side of the charger, the Micro-USB Input port and flashlight are on a short side. The power button and 4 LED power capacity indicators are on top of the power bank. Surprisingly, the power button is actual a major functional part of the power bank because you have to press it to begin charging. The power bank turns off automatically when there is nothing connected to it, though. Also, if you want to turn on the flashlight, you have to double tap the power button to turn it on; the flashlight isn’t really that bright and we don’t understand why there’s a need for it. Especially with this charger that already has a poor conversion rate.
Structure and Material

There’s nothing special about the structure of the Aibocn power bank. It’s separated into 3 parts with the main centerpiece and two side panels. The entirety of the charger is made of plastic. It’s going to last long as long as you don’t drop it. Dropping this portable charger wouldn’t bode well for the structure since it’s quite heavy and the shock during a fall would damage it.

The tech behind it isn’t anything special, much like the rest of the aspects of the charger. This because the power bank just uses normal Lithium A Grade batteries, so it doesn’t have the advantage of Panasonic battery cells. Although the power bank does take advantage of safety techs like Over-Charge, Over-Voltage and Short-Circuit protection to make sure your devices and you are safe during charging.

Reliability is actually quite lower when you put everything together. The power capacity isn’t really close to the initial power capacity of 10,000mAh and conversion rate can fluctuate quite a lot during charging so power capacity is all over the place. The Max Output of the power bank at 3.1A is alright but it would have been even better if both of the charging ports shared their Amperage capabilities, because if you’re charging 2 devices with the charger then there will always be a single devices that are connected to the 1 Amp port that will be charged slowly. If the Amperage were shared between the charging ports then the charging speed would be much more reliable and there would be fewer compromises.

The size isn’t very reliable for great portability because the charger is the size of a 20,000mAh power bank, while it’s actually a 10,000mAh power bank.
