First of all: If you're looking just a PowerBank for his cell phone, should look elsewhere because these nowadays there are already with more capacity in even handier form at cheaper prices. Equally wrong is the one who is looking for an LED flashlight with which one can illuminate entire forests. But who can know what to do with the combination of light source and persevering battery, which is used to even occasional charging USB charging enabled devices, it's no wonder.
The lantern dominates the usual RGB colors (incl. White) and -Farbwechselmodi that we know from other RGB LED light sources already. The brightness can be regulated in a few steps (but is the difference between min. And max. Fairly marginal). In the color change modes can be the rate of exchange (of hectic "Party Geblitze" to relatively relaxed slowness) rules. All this can be adjusted easily using the supplied remote control. Should this laze times, the individual colors and modes can also be switched by the power button.
Of course, good for hard arg only close to read, and then not for a long time, otherwise the eyes the brightness of constant white light even at the highest level. But in order to orient themselves in totally dark environment at least, but it was good enough.
The real purpose I would therefore be regarded as "Ambient Light", so as nice decorative lighting, night light or for camping. Thanks to the thick battery stamina with one battery charge is certainly phenomenal: Since LEDs consume less than 0.17 W of power, the battery capacity of about 28 Wh enough mathematically for more than 160 hours. (28: 0.17), which is more than one weeks continuous light, which can be further enhanced if one down regulating its brightness to Min. (what, pure brightness on, hardly makes a difference, as I said). For me, the lantern has already blown the first 24 hours, and still light up all 4 blue LEDs capacity.
The USB output (the usual USB 2.0 A-Male) invites with up to 2.1 A (when charging cable and device to be charged to participate) and is therefore on the amount of time. Is somewhat disadvantageous only the long loading the Lantern batteries because the electronics at this point limits the current to 1A. Charging takes then at the usual voltage of 3.7 V LiIon or greater than 28 Wh battery capacity "from completely empty to completely full" already mathematically almost 8 hours (28: 3,7). In practice, the manufacturer's specification of 8-9 hours should therefore be realistic, but also only when a charger is connected, which also provides 1 A current. On a USB 2.0 computer port often flow only 500 mA, it takes twice as long. Positive is, after all, that it is in the charging port to the usual USB Micro B connector, which is now common in almost all USB-charging enabled devices. Say: You can charge the part with his mobile phone charger or -USB charging cable.
The case is "only" plastic, but really very solid and high quality finish. Shake or rattle is doing nothing. The extract of the lamp head is pleasantly tight, but not too much, just right.
Overall, a nice little gadget that might be a bit expensive, in appropriate environment but does a good job.
