I have a 2000 Lincoln Navigator that was my father-in-law's it sits in front of our house and gets driven about once every two weeks.
We keep it for the winters (its really good in snow) but with the alarm system, it keeps draining the battery (even with a solar battery minder) to a level where it won' t start. I bought several battery jump-start units (most come with things you will never use like a air pump that takes a week to inflate a tire) none of them were reliable enough to start the car from near dead battery. When I received the DBPower battery it i was very surprised to get it in a great zippered case that holds the battery and all the accessories and it is still small enough to fit in a large glove-box or center console. I decided to test the unit.
1) I fully charged the unit
2) I disconnected the battery from the navigator
3) I started the navigator with just the jump-start battery. Not just once but 6 times in 35 degree weather! And it still showed the charge was at 100%.

It comes with multiple adapters so you can use it for other electronics. I used the battery for about two hours to power my Thermaltake Dual hard drive holder while I backed up a couple of computers and still had 93% charge left.
Setting it up to jump a car is very easy. My wife who is not mechanically inclined figured out how to plug-in the jumper cables and connect it to start the car in just a minute. I leave this in the navigator and pull it out about once every three weeks to make sure it is at 100% charge or when we go to drive after it has been sitting for a couple of weeks. This is great for peace of mind!

DB 600 A Jump Starter Works Great! Built very solid. Excellent build quality. I purchased this mainly for high a compression motorcycle engine. Starts on the first try now.

I also tested its ability on a V8 engine with the 1000 CA battery completely disconnected. From unit 100% fully charged, it jump started the engine 10 times, and also jumped my motorcycle 4 times; and ONLY drained the unit to 72% indicated.

VERY IMPORTANT....When jump starter cables are plugged in to the unit, they are immediately live and hot instantly, even with on/ off switch to off. On/off switch only activates the USB portion. BTW, from 100%, unit drained down to 60% and charged phone 3 times.

Therefore, it will probably charge your phone 9 times from 100%, and it will probably jump start your car more than 20 times based on my testing of a V8 engine, from 100%. Its light worked very well and bright.

For 65$ on Amazon, and 3 yr warranty, this is a very good buy! I spent a great deal of time researching the different ones on youtube, and went with this one because of its quality and warranty. There were no good videos on this unit, so I made one myself:soon to be posted. My 2nd choice would be the Uxcell 600A for 48.99, but it did not have digital display, and build quality seemed inferior to the DB 600. There are most likely 3 diff manuf. out of china, that make all the diff models.

Jumped a car at work, BMW X5. Was sitting on my tool box in my stall, the seem blew up into the air, the battery was expanding. I grabbed it with a pair of pliers and set it in the center of the shop and it exploded about a minute later.

This review is for the red/black 18000mAh jump starter.

Included with the 18000mAh jump starter are the instructions, a micro USB charging cable (approximately 2 feet in length), a wall adaptor with a round barrel plug for charging the jump starter (approximately 3 feet 2 inches in length), a car plug adaptor and cable with a round barrel plug (approximately 3 feet in length), car battery clamp cables (approximately 10 inches in length for positive clamp and approximately 6 inches for the negative clamp), a semi-hard carrying case, a dual end round barrel charging cable for things like laptops (approximately 9 inches in length) and 8 round barrel adaptor plugs of various sizes.

One of the common issues with these jump starters is that the car battery clamp cables that typically come with the set are in my opinion too short and that is the same in this case as well. I think the jumper cables are too short and for some cars such as my SUV that has a battery in an odd location, it makes it difficult to find a place to sit the jump starter when you are trying to use it. The battery clamps also use plastic handles that I am not crazy about as I think they need to be a bit sturdier but they do the job. The laptop charging cable is too short as well. In addition, there are no Apple adaptors or charging cables included, which is a minor issue to me since they are easy to add to the kit at little cost but a bit odd they weren’t included.

The included instructions are not particularly great. Multiple languages are crowded together making it difficult to read through. The English instructions are not particularly well written either in addition to lacking needed details. One thing that concerns me is that the instructions have a warning that this has to be charged over 25 percent or it can cause damage but doesn’t give the reason or specify what can be damaged (whether it damages the charger or what you are jump starting). If that is the case, why not have a safety feature that will not allow you to attempt a jump start if this has a 25 percent charge or less.

The instructions do indicate that this has a 3-year warranty which is good. One nice feature inside the semi-hard case is a chart printed on a plastic insert on the inside that shows what size jump starter is needed for the engine size. The chart is an easy reference for determining if you have the right sized jump starter for the size engine you have and should be something included in the product description page. I have read some reviews indicating that they are using the 8000mAh jump starter and having issues at jumping. According to the chart, an 8000 mAh jump starter is only capable of jump starting 4 cylinder (less than 2000cc) engines. It could be that the jump starter is too small for what is actually needed.

The reference chart could use more distinctive terms in the fact that it uses “good” for when the charger is fully capable of jump starting a particular engine size but the chart also uses “fine” that I am guessing means it is capable but most likely for just one attempt. The chart does clearly outline when a particular mAh jump starter is not capable with “no” in the listing. The chart also conflicts with the poorly written instructions with a statement that says that the jump starter should be at least 50 percent charged before using whereas the instructions say 25 percent.

I have attached a photo of the included chart for reference to make it easy to determine the size needed for your engine size but I will briefly summarize what the chart indicates the jump starter requirements are (for this brand’s starters at least).

If the charger is:
5400 mAh or less – It will not charge a dead car battery of any size engine.
8000 mAh – will jump start a 4-cylinder engine battery and nothing larger
12000 mAh – Can jump start up to 6-cylinder (less than 4200 cc) engines
15000 mAh – Capable up to an 8-cylinder (less than 6000cc) engine but may only have one jump for an engine that size.
18000 mAh – Can jump start 8-cylinder engines and smaller with no issues.

As for the device itself, it has a nice look with its red and black casing. Due to the battery size, this has some weight to it. The case is made of plastic, which is typical of these devices, that seems to be made pretty well but I am not sure how well this would hold up to being dropped. The instructions do warn about dropping this which makes me wonder how well they protected the electronics on the inside. In my opinion, something like this should have some shock proofing on the inside. One small issue I had with mine is that the round output charging port was not properly seated into the case but I easily fixed that by pushing it down a bit until it fit into the slot as it should. I am not sure but this could have been something that occurred in shipping.

The side of the case has the jumper cable ports (protected by a silicone cover), an on/off switch, 2 USB charging ports, a power switch (which should really be labeled a selector/option switch as it activates the emergency lights and changes the charging mode of the device), a round output port and a digital display.

Since a jump starter is basically a higher capacity power bank, this has a lot of the same features along with the addition of its ability to jump a car, with some of those features being more useful than others.

Compass – The basic compass is on the top of the case and is to me not particularly practical. It is small and hard to read and not really a useful feature with a heavy charger.

Flashlight/red emergency light - The flashlight, located at one end of the charger, is typical of those that are included with these types of devices. The light has 3 modes (steady light, strobe and SOS) and is bright enough for lighting up the immediate area when you are trying to connect the cabling to your dead battery. The light is activated by pressing and holding the power button. The flashlight mode is changed again by pressing and holding a second or third time for the strobe and SOS feature. Quick press twice for the flashing red emergency light, which is located on the top of the case by the compass. I would have preferred a separate switch for the lights to make it a bit simpler to use.

USB charging ports – This has two charging ports and although the badly written instructions don’t indicate it, the ports appear to be intelligent charging ports as they are labeled “smart output” under the ports. The product description on the Amazon page indicates these are 2.4A smart ports but the display on the device indicates 5v 2.1A. I tried charging both a Samsung S6 and an I-phone 5 in each port. Both ports charged them with no issues. I also tried charging a couple other USB devices such as a tablet and Bluetooth headset which charged as well. Unfortunately, I don’t have my old phones any longer, so I can’t say how well older phone devices will charge, however it does appear the smart ports will work with any device.

Digital display – The display is a bit small but a nice feature which shows the percentage of the battery remaining, has a blue LED backlight along with the charging mode the device is in. The device also has an auto shutoff that turns the display off (even with the power switch on) after about 30 to 45 seconds of inactivity. Another fault of the instructions is that none of those features are mentioned. In addition, the various charging modes and what should be selected is also not mentioned in the instructions. For example, there is a 16v and 19v mode that I initially wasn’t sure what devices I can charge with. I later discovered that the 19v was for laptops. I presume the 16v is also for laptops or similar devices.

Laptop charging – (using round barrel port) – I have a Toshiba Satellite laptop that is approximately 3 to 4 years old and after finding the right adaptor among the 8, I plugged the cable in. I initially could not get the charger to charge my particular laptop. With the lack of good instructions, I, at first, thought I had a defective device, cable or this wasn’t a fully functioning feature. I discovered through the process of trial and error that the charger does not automatically switch to the right charge for the round barrel output port and that you have to manually select the proper voltage. You also cannot change the power mode once this is plugged into the laptop. So if you have the wrong mode selected, the laptop will not charge. I presume that is a safety feature but with no documentation on the feature, I cannot say for sure. I checked that my laptop uses a 19v power adaptor and without the help of the instructions, I found that once I selected the proper voltage (in my case 19v) prior to plugging in the charger to the laptop, the laptop started charging normally. The laptop charging feature isn’t a big issue for me as my primary use for this device is as a car jump starter but the instructions really need to address how to properly use this feature.

Charging time – Because this is a large sized battery it takes several hours for the jump starter to fully charge. Mine arrived 97 percent charged but still took 30 to 45 minutes to get to 100 percent.

Jump starting – Since this is the device’s main purpose, I tried this on two different cars. My SUV which is a 6-cylinder engine (3.0 liter) and my car which has a 4-cylinder (2.0 liter) engine. This device started both cars with no issues and still had plenty of power left to jump start again if I needed to do so. The jumper cables are a bit difficult to remove from the jump starter due to the lack of enough gripping area on the plug. The gripping area of the plug needs to be a bit larger area as it is hard to remove without grabbing the wiring instead of the plug.

Durability – Despite the bad instructions, the device seems to be well made, however with any battery powered device, how well it holds up long term or to being dropped is the most important factor. It has held up well so far to being used several times as a charging device and a few times a jump starter but I haven’t dropped it. I will update my review with any long term durability or warranty issues.

Safety Features - Although the Amazon product description indicates that this device has over current, short circuit, overload, over-voltage and over-charge protection, the instructions do not reference this at all. With the 25 percent warning in the instructions and none of the safety features mentioned, it does give me some concern about what type of safety features this device has. Maybe this is due to poorly translated or lacking instructions but if these are included features, why wouldn’t the instructions at least briefly discuss them. Considering the price of the device, most likely these safeties are built in but this is another case of how poorly translated and lacking instructions hurt my impression of the device.

Pros:
Good 3-year warranty
Nice carry case that includes a car charging reference chart
Lots of accessories (See cons also)
Amazon product description indicates several safety features (see cons also)
Has a flashlight/emergency light
Has a separate Off/on switch and also has an automatic shutoff after a period of inactivity
Has 2 smart USB ports that work for both Apple/Android phones and other devices
Charges laptop (with the right setting, see cons)
Digital display that indicates battery percentage and charging mode
Display has blue backlighting
Enough power to jump start 8-cylinder engines

Cons:
Poorly written instructions that lacks needed operational and technical details
Safety features also not well documented in instructions
A bit heavy for a portable device
Short jumper cables/plastic clamp handles/a bit difficult to remove plug
Short laptop charging cables
Lacks any Apple charging cables
Compass is small and not particularly practical
Doesn’t automatically select the correct setting for laptops and instructions lack documentation in regards to manually setting this
Digital display a bit small
Flashlight mode selection is a bit cumbersome since it lacks a separate selector switch
Expensive (currently 90 dollars)

This is for the most part a solid device with a good warranty that has the capability of charging a variety of devices and jump starting most car engines. There are a few cons such as short jumper cables and being a bit expensive (currently 90 bucks) for what is essentially a high capacity power bank but this device is mainly hampered by its very poorly written instructions that lack a lot of needed operational and technical details.
