For comparison, the Romoss Sense 8 Plus 30000mah weighed 671 grams.
The manufacturer placed all the main interfaces on the top end of the device. Looks nice on the outside, but really bad.
Tested with xiaomi mi6 phone charging: Such a capacious battery, charging in normal mode would be very time consuming.
Mobile devices charging, but not as fast as we would like: The charge current is set at around 1.8A most of the time (for both ports separately). The time required is only 8 hours 36 minutes. The situation here was not so obvious. Review published in accordance with clause 18 of the Rules Cons: lack of fast charging protocols, easily scratched case, poor bundled cable, long recharging through one input. The list is not rich, all the same, the model does not claim fast technologies.
Each port individually keeps the operating currents within the allowable voltage drops . Weight – 605 grams. – cable, For some reason, the seller has the number 6.8A on the page, while in the specification for the product itself there is only 4A.
The complete cable is branded, with branded insignia on the connectors. It turned out that the USB1 USB2 (connected) and USB3 ports are very different in this regard. Packaging made from recycled cardboard, with company logos and an image of the device itself.
Conclusion.
Useful output capacity when discharging in 5V \ 2A (or 10W) mode was about – 20400mAh or 98W.h. Suitable for use on long hikes, outings, three full-fledged USB ports will be just what you need and will allow you to charge up to three devices at the same time. — Apple2.4A Therefore, the manufacturer got out of the situation by adding two inputs at once. The reason was the shaking of the device and, accordingly, friction on the cardboard. But I would like to see better results.
On the front side, in addition to the brand inscription, you can also see a large
charge level indicator, presented in the form of four blue LEDs. * Input: microUSB microUSB, 5V 1.8A, 5V 1.8A individually or 5V 3.6A together
Unfortunately, there is no Russian among them.
In total, the power bank can give a little more than 4A for a long time with a voltage drop of up to 4.8V. ALLPOWERS AP-PB-001 is by today’s standards a very simple model that does not have support for modern fast charging protocols.
Next, I tested the presence of a pass-through mode.
Having finished with the external examination, we proceed to testing.
On the back is the model and its technical features.
Next, I checked the presence or absence of a low-current mode or a mode for charging low-power devices (usb – flashlights, bracelets, headsets, etc.). The three USB ports are similar in this regard:
This is the second model of an external battery with such a capacity, which turned out to be in my hands.
If you connect two inputs at once, then the total charging power increases to almost 19W or 3.6A at 5V. It’s better to throw it away and take it better. The product was provided for writing a review by the store.
Compared to iPhone 7: * Output: USB1: 5V/2.1A; USB1: 5V/2.1A; USB3: 5V/2.6A (max) individually or 4A in total If we go from left to right, we see: a power button, two microUSB inputs and three USB-A outputs (USB1, USB2, USB3). * Size: 175mm*113mm*23mm USB3 output supports pass-through charging, no voltage drop: When simultaneously charging the external battery itself, the return on the output is purely physically present on all three outputs. * Capacity: 30000 mAh Capacious, but not fast.
— Samsung 5V 2A – external battery, There are no technical specifications listed anywhere on it.
And USB1 and USB2 does not actually support this mode: Speaking of the pros, this is, first of all, an honest internal capacity, automatic power supply to the ports when consumers are connected, not a lot of weight, the presence of three regular USB ports at once, support for pass-through mode and charging mode for low-current devices. As usual, I started by checking the supported charging protocols. The model has both its interesting features that can be added to the pros, and some disadvantages. During the inspections, several interesting points emerged. If you study it a little, you can understand that the model is based on lithium-polymer (flat) batteries, and its USB ports have certain features. Looking ahead, I will say that this observation will still make itself felt, but I will talk about this in more detail later. But if USB1 and USB2 have a strong voltage drop, even under a small load, then USB3 behaves absolutely adequately. For everyday wear, 30000mAh is definitely not the best choice, given the weight and dimensions. Specifications: By the way, the cover was already slightly damaged out of the box. In fact, USB1 and USB2 support low-current mode (without time limits): In terms of performance characteristics, all three outputs are almost the same: This is due to the low power consumption, approximately 9.5W. — DCP 5V 1.5A – instructions Her case is made of black matte plastic, without any frills. A simple but capacious 30000mAh Allpowers AP-PB-001 power bank with three full-fledged USB-A ports. And if the first one (Romoss Sense 8 Plus) was made in the form of a thick, but not wide brick, then the current one, on the contrary, is very wide, but not thick at the same time.
The physical dimensions are as follows: 173mm long, 113mm wide and 23mm thick. The manufacturer would not place to pack the goods additionally inside also in a package. Which can be quite regularly involved at the same time.
