This power pack combines many charging capabilities: mobile devices, laptops, and a car. This unit performed exceptionally well with my mobile devices (details below), jumper cables measured with a volt meter showed 12.24v which is sufficient to start a car, however it did not perform well recharging my laptop as I will detail below.GENERAL~~~~~~~~~~~~~~~~~This power pack is fairly small in size. The power pack itself is 3"x6"x1". It comes with a 7"x10"x1.5" faux leather case, which holds the unit and various cables and connectors that come in the package.In addition to charging functions, the power pack has a led light. The light is very powerful and bright. It also has several modes: in addition to the steady light, it has a fast blink, and a slow blink. I plan to keep this charger in the car, and the blinking function could be quite useful in emergency situation.I am attaching a photo collage that I will be referencing in this review, the photos can be located by following 'customer photos' link under the main photo. Photo #1 is a photo of the leather case with all the items included in this package. The package include 7 connectors for mobile devices, 8 adapters for laptop power port, and also includes a wall outlet adaptor, 12V car charger, and jumper cables with battery clamps.MOBILE DEVICES~~~~~~~~~~~~~~~~~The package contains 7 connectors for mobile devices, including mini USB and USB. The other connectors are not labelled and not explicitly listed in the documentation. I have tested this unit with four of our mobile devices (Nexus 7 Tab, Galaxy Nexus Phone, Galaxy 7.7 Tab, and iPad Mini). Mini USB fit my Nexus devices, but none of the included plugs fit iPad Mini or Samsung Galaxy Tab 7.7.I always use the same test to measure the performance of various power banks so I can compare the relative performance of each unit. I charge various mobile devices for 10 minutes and measuring how much each unit was charge in that 10 minute period.Here are the results of my tests with LuguLake 12000:&#10004; Nexus 7 Tab:_____________________3%___ AC source&#10004; Samsung Galaxy Nexus Phone:______8%___ AC source&#10004; iPad Mini:______________________ 4%___ AC source&#10004; Samsung Galaxy 7.7 Tab:_________ 4%___ AC source (with charging cable, discharging with a data cable)I use Battery App by Elvison to determine how each device recognized the charging source. 'AC' status means the charging is at full charging rate. 'USB' status indicates charging at a lower charging rate. 'Discharging' status means that the charging rate is below the power that the device is consuming so it slows down the discharge rate but does not re-charge.Photos #4,5,6 show the various devices as I was running the tests.Prior to this battery pack the best test results I got was from Yubi Power YP840A 8400mAh (Nexus 7 was 7%(port1) and 4%(port2), Nexus phone was 7%(port1) and 8%(port2), Samsung Galaxy 7.7 3%(port1) and 0%(port2). As you see this one is on par or better with the best I have tested.JUMPER CABLES~~~~~~~~~~~~~~~~~To test the jumper cables, I attached the volt meter to battery clamps. As you can see in photo #2, the reading is 12.24v which is sufficient to jump the car. I now keep this case in my car and will update this review when I will have a chance to use it to restart a dead battery.To jump the car the power back should be more than half full of charge. There are 5 lights that indicate the charging state of the pack and it should at least 3 light out of 5 on with a steady blue light. The manual recommends recharging the power every three months when it is not in use.LAPTOP~~~~~~~~~~~~~~~~~The package contains 8 adapters for laptop power plug, and one of them fit my IBM laptop.&#10004; Laptop:_______charged from 20% to 35% in 30 minutes (external battery pack went from 100% full to empty)By comparison, Intocircuit Power Castle Series PC26000 power pack, charge the same laptop from 5% to 69% in 1 hour (external battery pack went from 100% full to empty).When LuguLake 12000 was done charging my laptop, I touched it to unplug from my laptop and had to drop it back on the table. It was extremely hot. If you use the power pack to charge your laptop please be careful how you handle immediately after it finished charging. The unit cooled off in about 10 minutes.OTHER NOTES~~~~~~~~~~~~~~~~~1. The labels for outlets on the unit are written in faint grey font, they are hard to see on white background. Input and output ports look very similar, and the labels are very important.2. The package itself and the manual are aimed at a Chinese market. Some of the writing in the box does not have English translations. The manual has one side in Chinese and the back in English. All but one page of the manual appear to have the same content, but Chinese language has one page that was not translated.I received this unit for evaluation and testing from manufacture. Based on the tests it performed very well with my the mobile devices, but did not do well with the laptop. I also like the leather case that keeps everything neatly together.Ali Julia review
