Bolt Power D28 500 Peak Amps With 13600mAh Portable Car Battery Jump Starter Review

Online purchases are often a hit-or-miss situation in terms of quality, in particular with Chinese products and their surging exports. This item was a hit. I purchased the D28U late last year after checking reviews here and from other sources. It is manufactured by the Dongguan Juxing Power Co. of China, and sold here by Tii Trading Inc. < tiiusa[dot]com >, a seller with a high positive feedback from customers. The device received a high rating by Consumer Reports, taking second place under a more expensive device, and high positive reviews from verified-purchase customers here, currently at 95%. Except for one case (properly identified), I found no reviews exchanged for a free or discounted item, which must contain the FTC-required disclaimer — to me, it is a good sign when a company eschews the misleading approach of sock-puppet reviews or votes. I ordered the unit with two different purposes in mind: one, based on the high ratings, to keep it in my SUV, particularly for trips where emergency road service is unlikely; the other, based on a 2016 review here, to use it as a "mini-generator" for excursions and camping. Until last week, I had only used it to recharge small items, to power a small air compressor, and to provide flashlight illumination for long periods. For these tasks, the D28U works very well, holding its own charge much longer than expected. (Although I had ordered a unit with a single USB port, I received the updated model with two USB ports, which proved most useful for avoiding fights on whose phone to charge first. )Last Sunday I could finally test the D28U as a jump starter, when it saved the day of a kayaker who had parked her big pickup with a lame battery in such a tight spot between rocks and trees that the truck could not be jump-started with typical car-to-car cables. It was done easily with our unit by a closely supervised 12 year-old, who had dramatically argued she needed that experience for any zombie invasion (but was appalled at having to follow instructions printed on a paper by her father instead of reading them from a smart phone "as normal people do"). Live and learn. — [ ADDITIONAL ] –If you have never jump started a battery, or used this device, the following may be relevant:1. The unit has sealed lithium polymer cells, and no parts inside can be serviced or replaced. That means you use it for its expected 1000 recharging cycles –and not "circles" as its misprinted sticker reads– and then you throw it away with proper disposal (lithium is a corrosive alkali and a respiratory tract irritant). 2. The U.S. website of the company < boltpowerusa[dot]com > gives a contact telephone number (which happens to be that of Tii Holdings) and an email address; the details of the limited warranty for the power unit itself (1 year) and external attachments (2 years); and a FAQ on the unit and its operation. The FAQ is in the "Support" tab, and it is more understandable and applicable than the brief User Manual in tiny font provided with the device. 3. Read the FAQ. Read the FAQ. Read the FAQ. 4. Be patient when charging the unit. Fully charging takes many hours even with the unit already partly charged. It holds the charge for a long time when unused. 5. The device is a car battery *booster*. Boltpower says that the unit will not start a vehicle if the battery is "completely dead" (in the style of the Norwegian Blue parrot of Monty Python), and that it needs a "small partial charge" left in the battery to be boosted. Consumer Reports used a "weak" battery for their tests, defined as when headlights come on and the starter motor clicks but does not start the car. 6. The EC5 battery port, under a flap labeled "Start Engine," is always ON even when the device’s on-off switch (which controls other outputs) is in the off position. Its output is 12V with a start current of 250A and a peak of 500A (3 seconds). 7. The cables are very short — the separation tip-to-tip of the two clamps is only 21 inches; less if clamped vertically. This may have an impact on how to connect the clamps (see #9). 8. Boltpower claims that if you attach the cables to the battery terminals with the wrong polarity, a "detection unit" in the device will engage and try to fry the cabling to avoid damage. Significant sparking is likely to occur. 9. When trying to start the engine, do not crank it for more than 5 seconds. If it fails, wait at least 3 minutes to allow the unit’s heat to dissipate and the voltage recover before trying again; this should allow it to deliver its peak current once again. 10. There is a noteworthy difference between the jump-starting instructions of the User Manual and those of the FAQ . It has to do where to connect the black clamp of the cabling. The FAQ advises the best-practice technique of attaching it to a non-moving, thick metal piece of the chassis, instead of the battery’s negative terminal. The reason is to decrease the risk of an explosion caused by the ignition of potentially vented hydrogen gas if there were any sparking. That risk is mostly an issue when the cables are attached *first* to the good battery (or, for the D28U, when the cables are connected first to the EC5 plug), when sparking is not uncommon as the cables are then attached to the weak battery. So, be safe:– Check if the flat sides of the car battery are obviously swollen or bulging, or if there is rotten egg odor when opening the hood. If any of these are detected, do not jump start the vehicle but call a road assistance service. — Verify that the terminal to attach the red clamp is marked by a ‘ + ‘ symbol on the battery itself; do not guide yourself only by the color of the terminal(s) plastic cap(s), if any. — Do NOT connect the joined ends of the cables to the "Engine Start" EC5 plug before attaching the clamps to the weak battery terminals. -Read Reviews-
