I purchased this unit to meet three primary needs: 1.) To use on my vehicle for dead battery emergencies and tire inflation 2.) Maintain bicycle tires 3.) A portable source of emergency power, during power outages to charge small electronics such as a cell phone, etc. This unit has a variety of 6 outlets to handle your needs. In my opinion the current version of this unit is truly designed for the end user, with a well executed design and robust materials. What I like about this unit is that it has a large "easy to read" digital gauge located at the front, which allows the operator to preset a desired tire pressure, and allow the unit to automatically stop pumping when that number has been reached. The tire stem attachment has been updated from previous models, which only requires the operator to screw on / off the valve stem, vs. the old flip tab design which tends to wear out over time. I also appreciated the fairly quite compressor noise level, which was acceptable to my ears. Some units tend to be quite loud!
Had it for 2.5 years and it didn't start cars at all. All the functions (light, USB, inverter, air compressor) on the unit works fine except the major feature, start up your car fails. The multi meter reads 0 volt from the cable when the jump start switch is turned on. Contact the customer service but they said the product is only under 1 year warranty while the web site's "product warranty" PDF file says 3 years warranty for all DieHard products. I was asked to replace the internal battery of the unit for $35 but it simply does not make sense when the rest of the unit can power USB, light, and air compressor. Now this unit is used as air compressor most of the time and emergency light. This is one of the worst products on Sears. No wonder stores are closing. Very disappointed customer service.
I have had this unit for a few years, and the battery needs to be replaced now, after minimal use. But, was able to get good use out of it while it worked.
This is my second DieHard Platinum Portable Power station. Ive had the first one for 3 years and it has never failed me. We do a lot of camping and I tend to forget to turn off my cars stereo and wind up with a dead car battery when I wake up in the morning. NO worries as this portable charger has come to my rescue many times! When you take the unit out of the box it clearly states that you MUST charge this unit for 36 hours or permanent damage may result. It also states that you need to recharge the unit every 30 days. Ive read the negative reviews and im pretty sure that some people are NOT doing what is needed to maintain this excellent portable power station. Its a battery …...Its need to be recharged DUH! Great unit if you take the time to what is needed to maintain it!
