Power Banks are convenient to route your phone again just to give a boost. Can you do that as quickly as possible? Then PB10000QC3, and PB20000QC3 of EasyAcc may be interesting choices. Not only do these power banks through the regular method to 3 amps, they also support Quick Charge, which you can load even faster.
The past year we have repeatedly paid attention to power banks, especially since the beginning of the Pokemon Go hype there is a run on power banks arise, we have tested a total of now 55 of these kinds of mobile batteries. All of these banks power supply an output voltage of 5 volts, whereby the amount of current that can be delivered varies. Today we look at two power banks which are just a little bit smarter. EasyAcc namely power supplies banks with Qualcomm Quick Charge 3.0 technology. This charging stand allows – with mobile phones that support it – to increase the voltage to transfer so even more energy. We started off with 10,000 mAh PB10000QC3 of € 49, and the 20,000 mAh PB20000QC3 which costs € 89 euros.
The power that can deliver a power bank is easily calculated by multiplying the output voltage with the supplied current. A power bank which provides a standard 5 volt USB output 2 amp, it delivers 5 * 2 = 10 watts. Some banks will power up to 3 amps, and can thus thus deliver 15 watts. The higher power output, the faster a phone or tablet can be charged.
The USB port provides a voltage which is standard set at 5 volts, and the only way to increase the power supplied, is so to screw on by the current. But that creates problems. The average USB cable has such thin wires, the resistance is relatively high, and there are limits to the amount of power you can hunt safely and efficiently through.
Another way to be able to supply more energy, is by increasing the voltage. And that’s exactly what Qualcomm does with its Quick Charge technology. Chargers and mobile devices that support Quick Charge communicate with each other about the amount of power needed, and how that can be best delivered. At Qualcomm Quick Charge 3.0, this means that the voltage may vary between 3.6 and 12 for Class A devices. Class B devices can also supply 20 volts for a maximum power of 60 watts. Many mobile phones with Qualcomm QuickCarge 3.0 are not there yet, at this moment the offer is actually limited to the HTC 10 HTC One A9 G5 LG and the LG V20. Quick Charge 3.0, however, is backwards compatible with Quick Charge 2.0 and devices which support include the Samsung Galaxy S7, Note 7, HTC One M9 and the LG G4.
The power of Mobisun banks operate on the Quick Charge 3.0 Class A protocol. According to information supply the power banks at 3.6 to 6.5 volts up to 3A, from 6.5 to 9 volts up to 2A and from 9 to 12 volts up to 1.5A. Thus, the maximum current that can be supplied so slightly less than 20 watts. For phones that do not support Quick Charge 2.0 or 3.0 have the power banks have a normal Fast Charge port that always delivers 5 volt power supply and up to 2.4 amps. In practice, moreover, that the quick charge port at 5 volts with ease can make more than 3 amps to any regular phone or tablet.
Power Banks of EasyAcc are flat and wide and have a sturdy aluminum body with an anodized, deep blue finish. On the short side, we find a power button, a Micro USB port for charging the power bank with up to 2A in both models, and two USB Type A ports. One is a normal maximum 2,4A SmartCharge port that delivers to 5 volts, while the second connection support provides for Qualcomm Quick Charge. On the side we find four LEDs return to the status of the batteries.
The “small” power bank with a capacity of 10,000 mAh offers three lithium ion cells and large with a capacity of 20,000 mAh six pieces, said according to information comes to Panasonic cells.
The PB10000QC3 measuring 10.2 by 6.16 by 2.13 centimeters and is just 220 grams, while the larger 16.8 PB20000QC3 is large at 6.16 to 2.13 centimeters and puts 400 grams in the shell.
For the testing of power banks, we have developed a standardized and repeatable test method. As a basis we use here a CBA IV ‘Computerized Battery Analyzer from the American brand West Mountain Radio. This device connects to the PC via USB, then we can say exactly what amperage we want to discharge the battery pack attached. We have chosen a fixed discharge current of one ampere. Many modern smartphones can admittedly higher charging currents crossing, but not all power banks. In order to keep the test well comparable, we have therefore chosen for this value.
The CBA IV monitors continuously during the discharge process the battery voltage and current, so that the quantity of energy can be accurately calculated. In our large table with all previously tested models you can find it is actually available capacity for all devices back, and the lowest voltage during the discharge process.
In addition to the discharge capacity and voltage at 1 amp, we also looked at what voltage they still deliver the power banks at their maximum rated current. Unfortunately it is not possible to effect a Quick Charge handshake with our test setup, so the power banks see our tester as a “dumb” consumer, and thus always provide 5 volts. .
Finally, we have also looked at which current can supply the maximum power banks. For this we have still increased by 0.1 ampere current and looked for one minute that the machine continued to operate stably, and if so at what voltage. Some power banks can not exceed the specified amperage, while other models are pushing much further. This decreased voltage in some cases also have the below 4 volts, which is not desirable.
On the basis of our test results we can additionally calculate what is the energy density of the power banks. We have done this for both the amount of energy per liter of capacity, as for the amount of energy per kilogram of weight. In both cases, a higher value is better: in this kind of devices that route you take will have you after all capacities as much as possible into the smallest possible package with the lowest possible weight.
All power banks which we will discuss in this article have been tested new out of the box. How to perform the power banks after long periods of time have been in use or after a long time are not used, is not included in our reviews.
As stated above, is not suitable our standard test fixture to generate Qualcomm Quick Charge loads. We entrust the power banks as a normal “dumb” load, then power supply EasyAcc stable banks respectively to 3.2 and 3.6 amps at about 4.5 volts. These are excellent scores, which also energy-hungry normal smart phones and tablets can handle it just fine.
To see what the effect is when we use the power banks with Quick Charge 3.0 phone, we have done two tests with a 10 HTC, a smartphone that supports this protocol. Initially we charged the phone with a “dumb” 3 amps charger, which supplies all circumstances 5 volts. This lasted from completely empty to completely full 125 minutes to charge the phone, or just over two hours. Connected to the Quick Charge 3.0 output Easy Acc PB20000QC3 took the same test 89 minutes or tight half hour. That’s not a difference of day and night, but it does indicate that you can actually load faster with this power banks than with a normal model.
A powerbank preferably not only provides a lot of energy, because you use it on the go, by definition, it’s nice when it is small and light. In practice, those things difficult to reconcile, but there are big differences in the so-called energy power of banks. We calculated these density both to weight (Wh / kg) as well as to volume (Wh / l). In both cases, of course, that a higher score is better because you get more capacity per kilo or liter.
Because the power EasyAcc banks have shown in weight aluminum housing’re at a disadvantage compared to competitors with a plastic shell. Despite two power banks score above average on this point. we look at the energy density per liter, then we see the power banks at the top of the chart, where the PB20000QC3 even the best score by far delivers all tested models. Given their size power supply both banks so lots of energy.
The tested Power Banks of EasyAcc to convince with fine ontlaadprestaties. Support for Qualcomm Quickcarge is a great addition if you have a phone that supports Quick Charge 2.0 or 3.0. In that case, he will, in fact actually recharge faster with this power bank than a regular model. But when you have a phone or tablet does not support Quick Charge, this power banks are worth considering. They provide both clear with ease 3 amps at normal 5-volt devices, which is quite a lot. The larger PB20000QC3 additionally excels when it comes to energy-related format. It is by some distance the best we’ve ever tested at this point.
Would you like a light as possible powerbank these devices are not the most obvious. Because of their aluminum casing they are indeed tough, but also heavy. Would you like to sit for a dime at ringside, the EasyACC power banks are also not the best choice. At the time of writing, the devices are available only through Mobisun where PB10000QC3 costs 49 euros, and the greater PB20000QC3 goes on the counter for 89 euros. This gives a price of € 1.62 per Wh / Wh and € 1.37 / Wh on what reasonable, but no great price-performance scores.
Both devices are especially suitable for people who are looking for a well-built and especially very powerful power bank. Especially the big PB200000QC3 late-round show very good performance, which we crown this product with our Excellent Choice Award.
