Viking Smartech III QC3.0 25000mAh Black
Powerbank of this successor with product number: VSMTIII25G left us after 28 months from purchase. It holds 4 pieces in a series of flat 3.7V and 5000 mAh batteries.
The manufacturer misleads that it has 25000 mAh, because if we are talking about capacity at 3.7 Volt, it has 4 x 5000 = 20 000 mAh and not 25 000 mAh!. The first cell inflated and thus the entire powerbank lost capacity rapidly: (
Maximum satisfaction. I charge my laptop with it mainly on the train, where there is not always a working socket, or at the cottage and so far I have no problem. It is easy to use and quite robust. It's a little heavy when traveling, but given the capacity and power, it's understandable. Moreover, it is sold in a cloth wrapper so that it does not deteriorate as much.
DO NOT RECOMMEND! After a year of use, ALL USB-A slots are worn out so that even one of them practically does not hold any cable, in the case of USB-C even the inner part of the connector cracked in the middle (if it were micro USB, I would not say an inch - but in this case I have never had a problem with other devices - while I own plenty of HW with this slot. )
I have tried 2 times to claim unsuccessfully and each time the claim was rejected WITHOUT justification.
I'm done with Viking products - the almost 3000 that PB cost me at that time is practically money wasted.
I bought it as a universal power bank, I was looking for one that could power laptops. This type can extend the battery life of my Dell Latitude laptop by about 3 hours. It's not a problem to charge multiple devices at the same time.
Purchased two PB and neither works. You get the picture, for almost a year and a half they have not been able to respond to weekly emails.
