Authentic Feedback Analysis:
⭐ 5.0/5 | I***v: The package arrived via Nova Poshta Global in Ukraine within 14 days of ordering. The package was in good condition, and the inverter itself is perfect for my needs, working ideally according to the stated characteristics. The cable cross-section is 6 AWG. I definitely recommend the DatouBoss brand. Many thanks to the store and seller!
⭐ 5.0/5 | AliExpress Shopper: The inverter arrived quickly and was well-packaged. It’s of sufficient quality; I tested it and it outputs 230V. I ordered the 1200W model with a 2500W peak. It powers lights, a refrigerator, and a microwave. All necessary information is displayed on the screen. Recommended!
⭐ 5.0/5 | AliExpress Shopper: This is a very good and high-quality inverter, probably the only adequate choice at this price. It’s quiet – the fan turns off at low loads, it’s powerful, and it operates at the stated wattage. I recommend the seller!
⭐ 5.0/5 | a***r: I didn’t expect it to arrive in Ukraine so quickly. I connected it, everything works. Then I disassembled it to remotely extend the switch. I didn’t expect such good quality; China is ahead of Europe or the USA. Thanks to Datouboss manufacturers, the seller, and the carriers (received at Nova Poshta). It works perfectly, the best today.
⭐ 5.0/5 | AliExpress Shopper: Excellent inverter! I connected a Nivona coffee machine, 1450-1490W. The inverter works, beeps but doesn’t go into protection. Two cups of Americano without problems. I recommend buying it.
⭐ 5.0/5 | AliExpress Shopper: This is probably the best inverter among all Chinese goods. It’s not cheap, but it clearly delivers its stated nominal power, and one of its most important characteristics is its efficiency coefficient! It has 90%, while others have 60%, which means it consumes 30% less battery power and consequently lasts longer for useful work. This is my second such inverter – I gave the first one to relatives. Both work perfectly!
⭐ 5.0/5 | A***o: Shipped quickly, arrived in 2 weeks. Very well packaged in two thick cardboard boxes. The product itself looks good and works, but I haven’t used it much yet. The cables are thick, but the terminals could be better. I liked that the fan speed depends on the load, and if the load is small, the fan is almost inaudible. I hope it will work well and for a long time.
⭐ 5.0/5 | AliExpress Shopper: The package arrived quite quickly, considering it was a pre-holiday order! Everything seems to be working! I haven’t tested it under heavy load yet. I regret not adding a couple of hundred and getting the 2kW version. I want to especially thank the sales manager!!! He answered all questions clearly and quickly. If I could, I would give 10 stars for «Communication with the store.» Thank you for the package. I recommend the seller!!!
⭐ 5.0/5 | AliExpress Shopper: Super, everything is good. The inverter has M6 terminals, but the wires are M8. 11W consumption without load. USB only works when the inverter is turned on.
⭐ 5.0/5 | A***h: Ordering again, the inverter is super, it delivers as stated. Recommended!
⭐ 5.0/5 | D***G: Good old Datouboss. Nothing to say here, works like clockwork. Not my first time buying it.
⭐ 5.0/5 | AliExpress Shopper: I received a 1000W inverter instead of the 1200W I ordered. The seller refunded the price difference. Overall, the inverter looks high quality, compared to Tatali, it’s night and day. It holds voltage. Delivery 10 days.
⭐ 5.0/5 | AliExpress Shopper: Delivery was fast, within the specified timeframe. Works great. (Need to get a good LiFePO4 battery, as mine is old, and it will be perfect). The seller responded promptly to my messages. Thank you.
⭐ 5.0/5 | AliExpress Shopper: The product matches the description, received earlier than the stated deadline, I recommend the seller!
⭐ 5.0/5 | V***o: High quality, shows everything needed on the screen.
⭐ 4.0/5 | p***9: Very fast delivery. Haven’t tried it yet, so I can’t comment on quality, but it looks very high quality. Didn’t communicate with the seller.
⭐ 5.0/5 | n***r: I am very satisfied.
⭐ 5.0/5 | AliExpress Shopper: In principle, everything is fine, it holds a load of 1100W, but the cooling fan is very noisy and there is a smell of burning.
⭐ 5.0/5 | AliExpress Shopper: Delivery is normal. The product is good, only the cooler is noisy. Good packaging.
⭐ 5.0/5 | AliExpress Shopper: Decent inverter. I loaded it with 700W during testing — it holds the voltage.
⭐ 5.0/5 | AliExpress Shopper: Good.
⭐ 5.0/5 | AliExpress Shopper: Everything is okay, works normally. Withstands overload of about 1800 watts for some time (refrigerator startup). Refrigerator and freezer do not start simultaneously. At startup, the BMS would trip, so I had to increase the short-circuit protection delay time.
⭐ 3.0/5 | D***v: Before this, I took a 1000W one and everything worked; at 1000W consumption, it would beep and warn of maximum load. Now I took a 1200W one, and it goes into protection instantly when it reaches 1000W. The seller said this is normal… It made a strange sound on the first start, in short, I do not recommend it.
⭐ 1.0/5 | AliExpress Shopper: The product arrived faulty; smoke came out on the first power-on. I contacted them, they said to return it, and gave an address in Poland. I tried to clarify delivery details, whether shipping costs would be compensated, as it was stated that the seller pays (the post office only sends parcels abroad after delivery payment), but I didn’t receive a clear answer. Unfortunately, such a negative experience, although I bought goods here before, and everything was okay…
