Too many product make unrealistic claims. It's boring at best and quite troubling if a person falls for it by believing the story. This product defies any classification. Everything we list below are actual owner comments. 100% of the owner are in disbelief of its performance. - Mini Review by True Audiophile

A few customer comments:

A game changer
 
Better wear your diapers when you hear it
 
I came in early and sat down to listen, only getting up to change the sides of the record. Three hours later I had to tear myself away and do some work dreaming of hearing it again
 
Far better than you told me, and you told me it was revolutionary.
 
I am in utter shock, I cannot un-hear this thing
 
Its what I always dreamed playback could sound like
 
Audiophiles Are Always Looking For Clean, Undisturbed Grid Power To Achieve The Next Level Of Music Quality With Their Hifi Systems.

The Stromtank Makes Audio Dreams Come True... (we know that's trite but its very true)

One of the most important facts to hear the excellent quality of your audio-components is the purity and stability of the grid signal. Daily routine equipment like PCs or microwave influence the grid. Everyone is connected to the same dirty grid polluted with DC voltage, high level and frequencies. All interferences manipulate audio-quality and even the best power conditioners are not able to eliminate the disturbances.

What's Inside?

The heart of all the Stromtank units is the innovative battery technology known as lithium iron phosphate (LFP). Stromtank uses a special type of LFP battery that offers maximum power delivery, extended battery life, voltage stability, and intrinsic safety. The lifetime of Stromtank batteries is ensured by a battery management system that was specially developed in conjunction with the Fraunhofer Institute in Nuremberg, Germany – experts in efficient battery management technologies.

This Intelligent System Has Three Major Functions: 

Each individual cell provides feedback to the active battery management system.

• Active balancing of all cells in the array to maximize efficiency of discharging and charging cycles.

• Inspection of temperature, voltage, current load and state-of-charge of each single cell

• By monitoring and managing the battery array, the system is completely maintenance free

New Features 

Digital Distortion Suppression (DDS) at 1 outlet

  • Eliminates digital interferences from source devices
  • Avoids backwards interferences from sources to analog devices

12V Trigger 

  • External 12V trigger allows user to toggle between ON/OFF grid mode.

Warranty: 3 Years

Czech Review

“Stromtank has been conceived to become an ultimate solution to clean power supply. It operates with no dependency on power grid quality, providing the purest possible voltage to electronics. It proves once again – and it does so in a rather unrivaled way – that it is the power foundation that lifts up the good systems to the great ones. 

Are the Stromtanks expensive? It´s relative. They were designed for audio systems – including power amplifiers – not only for front end components. Often we pay substantial amounts for filters or isolation transformers that only work on players and streamers, and are forced leave the amps on the ‘dirty’ grid not to lose dynamics and punch. Not with the Stromtanks. 

Also, one can deduct few thousand of Euro from the Stromtank’s price right away. This is the budget that would be necessary for a good power cord if another power conditioner should be acquired. There is the rule that the best power cord one can afford should be placed between the wall receptacle and the power center of a system. The Stromtank does not really care about the power cord that feeds it. It is only used for recharging the batteries, the components will not ever see it. An ordinary PC cord will do the service. In fact, as I mentioned earlier, the Stromtank can be completely disconnected from the power grid. Do it as an experiment but do not use it like that – I guarantee that once you will forget to plug it back in and the batteries will be drained. But the message is clear: your audiophile circuit breaker means nothing to the Stromtank. Spend your money elsewhere. 

However, the strongest argument for the Stromtank appeared in the introduction of this review: it is the power foundation which is essential and which lifts up the good systems to the great ones. In my opinion the Stromtank beats any power supply solution that is on the market today, active or passive. I’ve got to get one…”

"I can't imagine one being disappointed with the performance of the Stromtank. And I'd bet even those audiophiles will hear an improvement in their systems because of the pure sine wave of battery power that the Stromtank delivers. The Stromtank cannot be compared to other power conditioners on the market because it isn't a power condition. It is power. Period. And that's the beauty of the Stromtank. Recommended? Are you kidding?"

Stormtank Q S2500

I have been following Stromtank for few years and reading all the raving reviews but I had serious reservations about what it can do. Typically, filters and so-called power generators not only do not help but they have negative impact on the sound. Stromtank is totally opposite of that. When I first connected my system, it was immediately clear to my ears that the Stromtank is the real thing. The resolution and significantly darker background are obvious but what hit me the most is the live like “energy” in the sound. I also have to mention wider and deeper sound stage. The operation of the unit is seamless. For my system, It provides over 7 hours of “off grid” clean electricity then it automatically charges itself. If you have a nice system, you owe yourself to get a Stromtank. Your system and more importantly your ears will be super happy.
