Good afternoon, dear readers. Today I want to tell you about the universal power bank Aili 116 or XW116. The power bank was specially ordered for the verification review and test, first of all, for itself. I also ordered model 119, but there is already a review for it, so today it will be 116)
The power bank itself is delivered only in a bubble wrap and with paper instructions printed on inkjet printer... Most likely this is the work of the seller, because on the back, there is an advertisement for his store.
Equipment 
Additional Information
I liked the appearance very much, just like the 119 model, it is made of high-quality plastic with a pleasant matte surface. The battery compartment opens by sliding, which is very convenient, you can use it as a charger. In ordinary whale power banks, fastening the lid with snaps and constant replacement of batteries is difficult.
As a charge indicator, 4 LEDs are used, each corresponding to 25% of the power bank's charge.
On the left side of the power bank, there is a voltage switch, with the limits of 3.6 / 5/6/9 and 12 volts. On the right, the microUSB input for charging the power bank, according to official information, the charge current of 2A holds - in practice, 1.5A, and this is a plus - it will charge less.
At the end there is a USB output, a 5.5x2.1mm output, a blue indicator LED and a 5mm "flashlight" LED.
Inside there is a board with a Hot Chip controller, a choke, a couple of mosfets, electrolytes and a powder.
Above there is a single button, it is responsible for turning on the load, indicating the charge and turning on the flashlight. The latter is turned on by double pressing the button and shines as a 5 mm LED should shine.
In this power bank, like in the 119 model, you first need to set the output voltage with a switch. For example, if you set the voltage to 5 volts, then it is present both on USB and on the 5.5x2.1 connector, and if you set any other, then it will be zero on USB. This is done on purpose so as not to burn smartphones.
At 5 volts, everything is just fine, with a load of 1A, the voltage did not sag. And at 2A, it sank to 4.8 volts, which is also an excellent result. Voltages 3.6, 5 and 6 volts also hold a good current, the only thing that causes problems is that the load must be high-impedance, if you just connect a light bulb, then the power bank goes into protection. At 6 volts, the current is 1.5A, at voltages below, respectively, even higher than 2A and 2.5A by 3.6 volts.
But the voltages of 9 and 12 volts at any load that I gave them go into defense. Even having connected the router, I could not get it to work. What is the problem - I have not figured out, but at idle these voltages are present.
Protection on the upper threshold cuts off at 4.15-4.17 V, and on the lower one by 3 volts. Such thresholds are practically on all power banks.
In general, the bank left a good impression. Its advantages are a good current at 5 volts - 2A, a flashlight, a high-quality case and a convenient cover - and this is a quick and convenient battery replacement, you can use it as a charger, the presence of additional voltages - albeit with reservations. There is also protection against incorrect voltages, only 5 V is supplied to usb! And the main disadvantage is poor performance in 9 and 12 volt modes, I will deal with this, most likely I got a marriage.
In general, if you need good 5V and a high-quality case, then take this one, and if there are high voltages and currents, then Aili 119 - voltage up to 21V and balancing charge!

Today, Power bank devices (autonomous Charger) have become part of our everyday life. They greatly facilitate the use of all kinds of modern energy-intensive gadgets, such as tablets and smartphones, as they allow you to quickly recharge in almost any conditions, when you are away from the outlet.
The simplest Power bank has only one type output - USB which is the most popular. In more advanced chargers
devices, you can find outputs with a voltage that has become the standard supply voltage for low-voltage devices - 12V. This is significantexpands the field of application of such Power banks, since almost any automotive electronics and many others work from 12Velectrical consumers. And when using an inverter, you can get 220V if desired.The cornerstone in these Power Banks is the issue of capacity. The use of modern high-capacity Li-ion batteries allowscreate in a compact size a power source of sufficient capacity to power any 12 volt device forseveral hours.
Unfortunately, manufacturers often save on the quality of built-in lithium batteries to reduce the overall cost.charger, which negatively affects the operating time of the Power bank. Therefore, we want to tell you how to make Power yourself.Bank using a kit consisting of a multifunctional DC-DC converter, protection board and housing and high quality lithium batteries of common standard size .
We will need:
Power Bank assembly kit model HCX-284, consisting of a multifunctional DC-DC converter directly, a protection board(PCM) for Li-ion batteries and metal case for 4x Li-Ion 18650 batteries.As lithium cells, we take 4 Li-ion batteries Panasonic model NCR18650B 3.6V with a capacity of 3400mAh
The HCX-284 converter has a stabilized 12V output with a maximum load current of 4A and a 5V USB connector with a maximum current of 1A. As a charger for our Power Bank, you can use any 12V power supply with a 5.5 x 2.5 mm pin connector andmaximum current not less than 1.5A. You can, of course, use a less powerful power supply, but the charging process in this case may takequite a long time.
The principle of operation of our Power Bank is as follows:
From a battery assembly of 4 series-connected (4S) Li-Ion batteries we get a nominal voltage of 14.8V. More precisely, it isvoltage during operation will vary from 16.8V (fully charged battery) to 12V (fully discharged). Directly tothe batteries are connected to the PCM protection board. She will control these upper and lower voltages, not allowing them to go beyondextreme values and protecting lithium cells from overcharge and overdischarge.
From the protection board, the voltage is fed to the input of the buck DC-DC converter, which turns our 16.8 - 12V from batteries intostabilized 12V and 5V on the appropriate connectors.
When the batteries are charged, 12 volts from the "DC In" input of the stabilizer are converted to 16.8 volts required to charge a 4S Li-Ion battery.The maximum current supplied to the batteries is 1A and does not depend on the capacity of your power supply. This allows you to use incomplete with HCX-284 lithium batteries with a minimum capacity of about 2000mAh, for which the charge current should not exceed halfvalues from capacity, i.e. about 1A.
Build process:
1. We glue a battery of four Panasonic Li-Ion batteries, model NCR18650B, using hot glue.
Hot melt glue is best used withlow melting point to avoid local overheating of batteries. Pay attention to the quality of the glue seams - they are notmust protrude beyond the dimensions of the battery, otherwise it simply will not fit into the case.
2. We use special electrical insulators to avoid contact between the nickel welding tape and the battery case.
3. Welding Li-Ion cells into a 4S battery using 5x0.127mm nickel tape and a resistance welding machine. Solder Li-Ionbatteries are not recommended because they are afraid of overheating, which can greatly reduce their life. Since the currents in our battery will be inwithin 3-4 amperes of this tape thickness will be more than enough.
We immediately form the leads of all voltages for subsequent solderingwires to control contacts on the PCM board.
4. Install the PCM on the battery. We form power contacts using only tape. It is more reliable and more compact. Control voltageswe connect to the board with wires of the smallest cross-section. We used MGShV 0.2mm, but you can use a wire and, for example, MGTF0.14mm.
The controller contacts must be connected in sequence from "minimum" to "maximum", that is, first "B-", then + 3.7V, 7.4V,11.1V and the last "B +"
5. Leads from the PCM are made with a wire ПУГВ 0.5mm. The length of the leads should be no more than 2 cm. We close the ends of the battery with insulating cables.arton and pack the batteries in a thin shrink film.
At this stage, we have a protected battery that can be used without fear of recharging or overdischarging. But at the exitsso far, we have an unstabilized voltage that will change during the discharge process from 16.8V to 12V.
6. We connect the battery to the stabilizer board. To do this, connect the black "negative" wire to the "P-" contact, and the red "positive" wire to
contact "P +" In this case, the stabilizer will blink all three LEDs once.
7. Install the battery with the soldered stabilizer into the case. We start the installation with the battery, then the stabilizer. Stabilizer boardis installed in special grooves of the case.
Everything. Our self-made PowerBank is ready. We check the work by clicking on the only button, which, when not connected
connectors, includes a charge level indication, which indicates that our batteries are now fully charged.
Let's calculate the total capacity of our Power Bank:
We used 4 Panasonic NCR18650B 3.6V 3400mAh batteries. In total, we get 3.4A / h at a voltage of 14.8V.
But we haveoutput 2 voltage 5V and 12V. It should also be borne in mind that the efficiency of the converter is about 90%.
Accordingly, at 5V, the capacity of our
battery will be ((14.8 * 3.4) * 0.9) / 5 = 9.05Ah This means that with a five-volt load with a current of 1A, our Power Bank will work for about 9 hours!At 12V, the capacity will be: ((14.8 * 3.4) * 0.9) / 12 = 3.77Ah
That is, in principle, the whole process. In terms of time, with experience and tools, it takes about 1 hour.
If you are not confident in our abilities, we Power Bank using any Li-Ion batteries present inour catalog.
In our store there are already assembled, ready-to-use Power Banks based on the H284 set.
