Porches of go on 27. 05.24G. 06.24 deadline for shipping beshe Hot on 04.06 Super byrzo Kakdo E glowing described😊
The Fry was dented packaging, the charge was 76%. This time they sent what they wanted. We will try and test. Ordered the bag separately.
Great booster! I take the second as a gift. Characteristics correspond to those declared. Recommend👌👍👍👍
Perfectly packed. The box is hard with padding from the password. It is clear that the company is worried about its product, so that it comes to the buyer safe and sound. The power bank itself is weighty 1.5 kg. You can feel the power in him. Powerful crocodiles with thick wires. Self set of wire accessories in charging kit and so on. A lovely booster. Worth the money. Quality power and reliability.
This is a very cool thing! Revives the dead battery. Charge holds very long! Assembled very well! I recommend everyone by all means! I am very satisfied with the purchase! Bought another one as a gift
Received in good condition, the quality looks fabulous I am yet to test it but that won’t be a problem.
Cool thing!👍 The delivery is very fast .. Seriously! Everything works without problems .. Engine V8 5,7 Hemi gasoline started with half a turn twice losing 7% charge is cool🤟At the same time there was an old dead battery twenty years ago, which in any way took part of the power on itself!!!☝️ The phone was charged with 30-100% with a capacity of 4000 mAh after spending 10% charge jump starter. Crocodiles huge, cable copper AWG 8. I wanted to order a similar yesper machine but it never reached me the seller promised fast delivery but a month and a half and a dispute in my favor, and this order arrived exactly in a week and the price is cheaper!!!
Happy to buy, works fine, and even at a good price! An indispensable thing on the road! The flashlight built-in is very powerful. recommend!
I think the best booster there is on Ali Express. Very satisfied with the purchase. Take it won't be willing.
The device is excellent! Heavy, powerful crocodiles. Came charged 76%. Immediately in the car put on charge from the cigarette lighter included. Up to 100 charged in 16 min, charging speed 120W. All the ports are working, the lantern too. I haven't tried to start it yet. Love the workmanship!
Good and responsible seller. When the item that I bought a bit less than one year stopped functioning the seller tried to help the problem. But it was obvious that the item was unrepairable after several attempts to revive it. So the seller did not hasitate and proposed to resend another new one. The new item has come from Moscow basement within two days! It is incredible! So I recommend the seller.
this is high quality product. The packaging the product and everything packed along with it is top notch. For the price it beats the others in quality. very happy with it.
Received within a week!!!
