Amazon.com: Customer reviews: TACKLIFE T8 MAX Jump Starter - 1000A Peak 20000mAh, 12V Car Jumper (All Gas, up to 6.5L Diesel Engine), Auto Battery Booster, Portable Power Pack with Smart Jumper Cables, Storage Case, UL Certified
I let the battery completely drain on purpose by leaving the headlights on to test out this battery charger. I have a full size Chevy Silverado with a V8 and this jump starter started the truck right away. Very impressed with this device. No longer would you have to wait for someone to come by with jumper cables or another vehicle.
I have not used the T8 Max for jump starting yet, but all components seem sturdy, case, jumper clamps, 12v lighter plug and USB connector/charging plug. I especially approve of the flashlights, a wide, bright spot on one end and soft light with red flashing option on the other, pretty much covers all the bases. The usb charging ports charged my cell phone and mini-drone about as fast as a wall charger. The T8 unit has blue indicator lights for charge strength that apparently stay lit constantly. Maybe the drain is not significant but I wish there was a way to turn them off when the unit was being stored to save the battery.
EDITED: 3/31/19 It turns out the charge indicator lights should turn off automatically after the T8 Max is charged. My unit was discharging constantly and after several days the charge indicators were already down to 3 bars from 4 bars when fully charged. It was clear it was not going to hold a charge for in storage for very long. After notifying the seller that the lights could not be turned off, they asked for a video to verify the malfunction. I sent the video and received a replacement unit within a few days. In the new unit, the blue indicator lights remain on for about 20 seconds and then turn off, it is an automatic function when working correctly. I still have not tried the jump starting with T8 Max, but have used the USB charging port and that works well. My five star rating stands, even though the original unit was defective, customer service was very responsive, the situation was resolved to my satisfaction and I believe the product will work as described when needed.
Edit 6/2/19: still no response from support. 1st support requested video of problem, sent, then cryptic message that they saw 1-star review and no further response, except emails completely in Chinese which google translated as automated response. BEWARE ALL THE FAKE REVIEWS, I'll post photos of cheap interior parts; Tacklife = junk.
Original Review: Got one use only. Needed to use built in lights. Once battery ran dead it could not be recharged, single blinking red/blue light never changes and will not recharge after numerous attempts. Charger output nominal per sticker. Absolutely worthless, look somewhere else. Edit: Been emailing support for 3+ weeks, so far, just generic responses, no action.
Bought this product. Fully charged and left in the car for emergency. After about 1.5 months, tried to use and did not work. It just beeps and light just blinks. Contacted Tacklife support for warranty and so far only responded with one email asking what is wrong and I sent them a response detailing its defects. Still waiting for a response after 5 days and counting. I sent another response just to follow up and finally they responded that they will send a replacement.
Just an update. So, a total of 9 days to get my part replaced with the warranty. I received my replacement and everything seemed to be working at this time. I was glad that they replaced the defective item and I did not have to send it back because it would have been more inconvenience. So, with that I increased the rating from 1 star to 4 stars.
I purchased this product Nov 1, 2018 through Amazon. I fully charged it as indicated by all indicator lights lit and put it in my vehicle for emergency purposes. The instructions suggest to recharge it every 3 months or so. Since I am about to go on a trip I pulled it out to do so, and found it was completely discharged. I plugged it in to the house current as instructed and the first light started flashing. In 4 hours the second light started flashing so I left it plugged in overnight. This morning the two first lights were on steady. I unplugged it and lightly tapped the power button and the first two indicator lights and the forth one came on momentarily and the went out. The third indicator light did not come on at all. At this point I am unsure if I have a fully charged unit or not, or do I just have a third indicator light that is not working. What do you think?
So far my only qualm is with the instruction booklet. The print is so small that I can't even read it with my reading glasses, except in bright light. I ordered one of those credit card-sized magnifiers to slip in the booklet (found a set of 4 high quality ones for $4.99. Can start a fire with one, too). I think a lot of these booklets are created by people too young to understand that that will be a problem for most after the age of 40. Especially in emergency situations where there is little light and higher stress. Also, the information regarding the LED flashlight is wrong. For that you need to hold down the power button, not the warning button. And there are four selections, including the off, not three. I think there was some cut and pasting that went awry when it was written. So far, everything else is fine. But have yet to use it in an emergency situation. It is compact and solid. Looks well built. Nice case that everything fits into. The cables are thicker than most other kits, which is nice. It's also nice that you can charge it in your car as you would a cell phone with the cigarette lighter, so I think they said it's a bit slower that way.
I got one of these Tachlife as a gift a few years ago. It is awesone! It jump starts my F250 diesiel truck batteries wothout a problem! I liked it so much I bought one for each of our adult kids for Christmas and for our other car.
The cables were an updated model from our original model, but I thought they would be easier to use since the boost button was an actual button now. The original model had a recessed button you had to stick a very thin rod into. (I literally used my earring post before.)
After opening them for Christmas, they were charged and placed into the trunk. Recently, I got the newest one out of the trunk to charge the mower battery. I tried, and tried, but could not get the boost button to actually charge the mower battery. Feeling frustrated, I waited for my husband to get home to see whatI was doing wrong. He tried and tried to also get it to charge the battery without success. He then pulled the old model outfrom his car swapped cables and then pushed the boost button. The mower started right up!! As much as I like the ease of an actual button for the boost feature it does no good if it does not work.
My husband and I really, teally like the original model and would give this model ALL 5 STARS IF the cable worked.
When I was a kid, I remember my dad had a battery charger and an extra battery for his truck. Not exactly portable. Ain't technology grand?! I ordered this guy after some quick review-checking in response to a dead 08 Honda Civic battery the night before. I grabbed the package off the porch when I got home, unwrapped it in the driveway and jumped the car in about the same space of time it would take me to make a cup of coffee with my Keurig. Brilliant! I'm going to buy one more for my Jeep GC EcoDiesel. The case with accessories by itself is worth the price, even if the jumper only worked on car batteries. The flashlight is aces. It actually rivals the Maglite I keep in all my vehicles. I'm charging my phone using one of the two output USB ports as I type. I'm going to use the DC adapter and plug it in to my portable air compressor. If that works, I can die and go to heaven.
I like that it holds a charge for a log time. I charged it when I got it in July and jumped my side by side 3 times and it still shows a full charge. I would have given it 5 stars but haven’t gone through a winter with it yet.
So I finally got a chance to put it to the test. Some lady's VW Bug had died out in the middle of the street. I walked over with this brand new battery. I clamped the red on the positive, yet the leads are so short and the battery inside of a VW bug is awkwardly placed to where you can barely reach the spot to place the black lead! To make it work one person has to hold the portable battery just above the vehicle battery while someone else connects the leads. So I guess the only downside to this thing is the leads are short and depending on the placement of the battery, it can be difficult to connect But the good part is, I never had charged the portable battery. It had 2 blue lines on the battery. But it still was enough to jump the Bug! Thus the 5 star rating.
I used this to replace an older power pack that was no longer charging after 6 or 8 years. This charger is about 1/3 the size and weight of the older charger and worked well out of the box. I charged it over night and this morning used it to charge the '92 3/4 ton ford ( 5.8L). After sitting for most of the winter with just a single start up, the battery would hardly turn over. This thing jumped it immediately. It is simple to use; charge the unit, connect to proper terminals and crank on the ignition. It also has two usb ports, a flashing red and a white light. The white light is either a continuous flashlight, a slow flashing light, or flashing S.O.S in the third position. Nice, powerful and compact unit. As an update... Days Later... I also recently jumped a 350 GMC '91 pickup. It had also sat over winter without being started for several months. It did Not start immediately. There was a bit of excess corrosion on the battery terminals. Once this was remedied, the truck started right away. Just remember, once a battery is truly DEAD, you cannot jumpstart it, you will have to replace it.
