Bolt Power D28 – first impression
This kind of devices called mini jump starters are for sure very compact and light. Bolt Power D28 is not an exception. Weighting only 2.4 pounds and a size of a Smartphone this jump starter can fit in every car drawer or under motorcycle seat.
The device itself comes with very useful and miscellaneous equipment, all together packed in a carrying case. This rich equipment makes it great to have not only in your car’s trunk or motorcycle but also as a power bank to recharge various types of electronics such as cell phones, tablets, Laptops, cameras… So, let’s take a look inside of this compact box to see what do we get with Bolt Power D28 device:
• Mini detachable jumper clamps
• One classic Home Charger (can be used for 110v outlet)

• 8 pin Apple lightning cable
• 30 pin Apple Charging Cable
• Slim & Micro USB Charging Cable (4 in 1 USB cable)
• Laptop Charger (8 different detachable pins)
All this useful equipment combined with an ergonomic design makes Bolt Power D28 very easy to handle and operate. Most of the similar products don’t have 8 pin Apple lightning cable but this one does have, what defiantly makes difference compared to other mini jump starters.
The unit itself looks pretty nice. Housing is build of shiny plastic material with recognizable green color on the edges. It is quality and durable plastic and fits in hand very nice.
On the front side, there is very bright flashlight. We found it very useful not only in a car but in a household too. In everyday situations when you are in need of flashlight just pull out D28 and problem solver. Interesting and great addition to the flashlight is that it has two operating modes, SOS and emergency strobe.
All of the outputs and input are located on the side of Bolt Power D28. There are:
• 12V Output Voltage of Jump Starter (place to plug in mini jumper clamps)
• 19V, 16V, 12V – 2A, 3.5A, 3.5A outlet (place to plug in Laptop, iPad or any other device who is using this voltage)
• USB 5V 2A outlet
• 15V 1A charge inlet
• Master switch
Besides all this outlets and inputs there is also an indicator light showing level of energy contained inside the device. Of course, you get instructions menu within the package but be aware of the tiny font who can be difficult to read even for those who don’t have vision problems.
As you can notice Bolt Power D28 offers various options of use. It is great device to have in your backpack as you go for a hiking or it can be used as a jump starter.
Bolt Power D28 – great mini jump starter!
Bolt Power D28 – a jump starter and a power bank contains 13600mAh of capacity and boost the power of 400 Amps. What it actually means is that this device can recharge Smartphone up to 7 times if used as a power bank. This characteristic puts this portable device high on our list of the best mini jump starters on market. On the other hand, 400 peak Amps are more than enough to jump start V8 gasoline engines. It is not recommended for Diesel engines especially heavy-duty Diesel since these kinds of engines require much more power needed to get started. For diesel engines check Micro Start XP – 10 or Bolt Power G06.
For the purpose of this review we have tested it on our Toyota Highlander (V8 gasoline engine) in order to confirm all these claims. But before even trying to jump-start your car, be sure you have read user’s manual. We have mentioned already that it could be a problem to read it so be aware of that possible problem. As you have read instructions you will notice how simple is to use it. Even if you accidentally do something wrong e.g. connect the clamps wrong way (this is a common thing to happen although it is an easy procedure), you won’t get injured nor your car will be burned. Reason for that is safety precaution build in this Bolt Power D28 jump starter called Reverse polarity.
So, what we did was to connect Bolt Power D28 directly to the engine in order to get the best from
this little device. As soon as we hooked everything in a right way we tried to start the engine and guess what? – worked as promised! We repeated the same routine few more times and the result was more than positive since we had enough juice to plug an Android and fully recharge it! What we found as a slight problem were short jumper cables. It is not something particularly related to this device but for all other mini jump starters.
In our second part of testing, we were using Bolt Power D28 as a power bank. Since it comes with a handy case full of different cables and detachable pins, all we needed ware dead batteries to be recharged. D28 was recharging HP Laptop and iPhone 5S simultaneously with no problem. Since USB output is running 2A it did recharge an iPhone for about 40 minutes. Quite impressive!
We were for sure very satisfied with Power Bolt D28. Whether used as jump starter or a power bank this mini jump starter did a great job and worked like a charm.
One of the most important characteristics of any device is definitely safe handling. If you had previous experience with jump-starting a car using just jumper clamps and another car as a source of power, you probably remember how risky the procedure was. Using Bolt Power D28 or any other mini jump starter you can be sure this kind of unpleasant and dangerous situations won’t happen. Reverse polarity prevents sparkling and doesn’t worry about overheating too if you leave it on charger longer than needed, but again try not to keep it on a charger all the time since it is a lithium-ion battery inside and it could be a problem. The housing also is pretty durable.
Other customer reviews of Blot Power D28 jump starter
Although we were very satisfied after we tested Bolt power D28 mini jump starter and power bank, we wanted to do an additional research. We were looking for other customer reviews in order to collect as much useful information as possible.
As expected for a device of such a good quality we found more than positive reviews. Customers are very satisfied with this jump starter and recommend it as a quality product. They claim that customer support for Bolt Power D28 is remarkable and it is something we didn’t test because we didn’t have any issues or inquiries about this product. But good customer support is one of the most important segments of product quality. We share you some of these reviews:
“So far, everything works as advertised. Already used it to jump a 4cyl Mazda generator, the battery was pretty dead, barely enough juice to make the starter “click”. Hooked this up to the battery and the genny fired right up, didn’t wait at all to charge the dead battery. Amazing how much energy is packed into these things.”
“Jumped a car 3 different times with no problem and without recharging. I feel much safer knowing I have this for emergencies.”
“It’s compact, smart, comes with car battery jump cables, a multi-prong USB connector to all of the current devices like phones, iPad, a laptop charging cable with a selection of connectors for most machines, and more. It has a power selector for a variety of needs, has a flashlight, and a nice sturdy blue carrying case with wall and car charger. I’m getting this for everyone on my Christmas list.”
At the end of this Bolt Power D28 review, all we can say is that this mini jump starter is a device worth of having. No matter if used as a power bank or a jump starter this small but yet so powerful device will meet all your expectations. It has been tested on V6 engine as jump starter and did a great job by starting our Toyota several times. As a power bank with a capacity of 13600mAh, this device is a must-have for those who use gadgets and other electronics especially in situations when there is no power source nearby (e.g. camping, hiking, traveling..)
Be sure you have Bolt Power filly charged as you may need it in emergency situations. It can be recharged in a car using a cigarette lighter or just plug it into a socket in your home. There are some things we found as something that should be done better. Bolt power D28 has only one USB output and compared to similar devices like Brightec SCORPION who has two it is a slight deficiency. But this is not even close to being a problem since the Bolt Power works just fantastic.
