So far, it has arrived at three of the four LED state of charge (= 75%). The description says that the four LED for 25%, 50%, 75% and 100% state of charge are. Since you a "state of charge" of my knowledge, can not be measured directly, but I suppose that the LEDs are connected to battery voltage (which is not likely to be directly proportional to the available residual capacity). Ravpower also points out that the charging rate may decrease with lower charging state. Well, at 2.4 A and 2.1 A has since some air. So, I have rather the problem of not being able to test properly - because I simply have no more charging problem, the charging time is somehow okay ;-)
For use during holiday periods as an independent energy source, I'm now definitely no more worries. However, I have (and rather invest money in capacity than in the number of connections) with intention for quite generously sized instrument gripped. My smartphone battery has a capacity of about 2000 mAh. So has the Powerbar more than 7 times. Since my smartphone is not every day is completely empty (but certainly needs to be charged every day), I expect to get through the holiday scenario two units a week with the help of Powerbar. As might a little bit Laden in the car to be there - but as for me is the constellation.
Ingenious: The Powerbar itself can be via USB charging - even while it is being loaded. Yes, that offer some, but time to think through: If you have a car USB adapter, you can even charge the Powerbar during the holiday arrival or the day trip! This makes for the huge capacity also sense (s. Charging time below). In the automotive AUKEY 4.8 A adapter is recommended, because then the Powerbar is almost incidentally charged while the smartphone full 2.4A can suck.
Very pleasing: It comes with two different length cable to connect two devices. The cables are run white (good optics in combination with the UG Innergie USB charging power supply unit) and as a flat cable. Thus they are short (no unnecessary tribulations while traveling), but still flexible (better than regular cable). I think that's pretty well thought out. For Samsung smartphones have the adapter is included on non-USB ports.
Backward Compatibility: Clever: It is still in an adapter of micro to mini USB. I can z. B. my older MP3 player, who still has mini USB, likewise invite. I had not yet found such an adapter and think, is absolutely in terms of the footprint (less Kabelgeraffel) just fine.
Disco: At last I can even criticize: The Powerbar has blue LED (as above Innergie), what looks good together with the white housing. I do not like it really so if too much "light pollution" is given. At night a room is as pretty bright. In addition, always switched on during charging after another LED, so that is still moving in the matter. Fortunately, you can simply turn the Powerbar on the back, then it is already dark. By the nice rounded housing but the room is still slightly illuminated. Well, you can try it also with the supplied bag when the part is not too hot. But I have not tried it yet (a little bit I'm looking just yet on the blue LED ;-).
Incidentally, the design (white / silver) is very close to what the Innergie Charging circuits (white / gray). Because there is a 15 W and a 21 W, because the Powerbar can with 1.5 A (or maybe more?) Are loaded. And usually a short time given loading facility to be used optimally so, why can load Powerbar and parallel smartphone to be ... For me, the Powerbar but intended principally for loading two smartphones to the holiday also a couple of days without power and without to be supplied drive.
What was not reported in the online Description: The device is fully charged at 1 A in 17 to 18 hours. But, I suppose, that it will never be empty because it then anyway can hardly a good smartphone charged fully charge expected. In the manual, the USB input is however given with 1.5A. And that reduces the charging time to a half day. And because the device from a couple of times Smartphone never load is so empty, it is likely the charge during an 8-hour sleep again have full or nearly full capacity. And for 1.5A make up the Innergie 21 W and the AUKEY 4.8 Adapter A sense because the make it possible to load one of the smart phones in parallel with 2.4A. If during the period of two smartphones are loaded, the way you can interpose the Powerbar. While "pulling" the smart phone faster current than the Powerbar invites (if really at the indicated 1.5 A conclusion). However, Powerbar is thereby hardly discharged.
A flashlight feature is the way to it also. Had I not needed, but who knows what it is good. On cell phone that is always tricky and costs somehow real power. So not so bad that the Powerbar has.
And a bag there are also. I suppose this is not because my equipment design like too good. But you can in pretty accommodate cable stuff without z. B. with cartons or boxes to sacrifice valuable luggage space ;-)
Again Plus: For me, the Powerbar came preloaded. The LED signaled 50% or 75% state of charge. Anyway, I was able to load immediately, I found cool.
PS: the use of energy sources with high ampere-numbers, one should always pay attention to the cable, otherwise eg long cables / small wire cross-sections reduce the charging rate (even if you have expensive charging technology at the start).. The accompanying here are obviously also suitable for the said current intensities (and therefore also the limited cable length makes perfect sense).
