Customer review

I got stuck last week with my car's alternator and battery being dead. This unit started my car 4 times that night and I actually used the supply to power the car so I could drive it an extra block to avoid paying a tow charge. It powers my hungry laptop for up to 4 hours between charges. I can't recommend this power supply more....all aces.
Update:
My unit failed to take a charge finally. I did have another unit that failed and a note of caution here. These devices are not perfected yet. True when they function they are unbeatable but they still can fail prematurely. When they work there is nothing better. The key here is price i think. I paid well under 100 and they have been recently priced at 149. I would not pay anywhere near that for the power supply as they do not last. If i had paid the 149 and it failed after three years that comes to a cost of 50 per years usage and that is not worth the cost. This power supply with a combined power inverter is a great idea, they just need to improve the quality of the battery within or make it so you can merely swap out the battery inside when it dies. Again, my experience has been awesome as to performance but it isnt a device which provides durability with certainty. If they made it so one could go to a battery dealer and get a replacement battery to insert then it is worth what they are asking.
Conclusion:
If you have a need for a solid unit and you luck out with a good one then you will not be disappointed until it eventually fails. It will provide you with stellar results until it dies. The question is this... Is it worth the price for the time it lasts? Only you can answer that. It is an oddity i think to find a product that performs so good yet is such a gamble. I would think that the engineers that designed this fantastic device would consider better quality batteries or a perpetually replaceable battery insert.
