Logistics: Seller's Shipping Method
I bought two batteries. The real characteristics are many times less than the seller said. Declared battery weight 1 kg. The actual weight is 840gr.
Declared capacity 30000 mAh. Actual about 6080 mAh. It's five times smaller. The output power is 70 watts. Measurements were made after fully charging the battery on a tested USB tester with a load in the form of a group of LEDs. Starting load current 564 Ma, U = 12,2v. Final voltage 9.975V, current = 0ma. Discharge time 12 hours 35 minutes. The seller does not recognize the measured testimony I have made several times. Offers to return the goods, in the hope that it is not everyone will do. Even when calculating a 3s6p circuit with a single element capacity of 3400 mAh, only 20000 Mah is obtained. I do not recommend this seller. He's cheating. Opened a dispute. Got a partial refund. But for me it's the money thrown out. For incomprehensible reasons, not all prepared photos for the dispute have been uploaded (size 1-2 Mbytes)
