A part of the review has been auto-translated.
At first glance, the product seems good, but in reality, the power is very low! The internal resistance of the electrodes is too high, even when compared to homemade electrodes. The internal resistance of the capacitors, although they are Maxwell, is also too high, around 0.5mR each, which is huge for this kind of capacitors considering that the internal resistance of new ones is between 0.15mR and 0.25mR at worst. So these capacitors are too old, charge slowly, and do not produce enough current. The control panel seems good to me, however, the charging circuit requires a fan for cooling because it heats up a lot, unlike the old version which had a fan. Charging time is about 30 minutes, which is too much. In short, I do not recommend buying it, please take a look at the images and you will understand.
As expected worked well with no problems!
