Just bought brand new 600x power station, nothing on it worked and lifting the product sounds like everything inside is loose making me wonder are their products even safe, bought from UK official vtoman store, no response from them.

Just received my VTOMAN 1500. It's not as heavy as I thought it would be. I now own 2 VTOMAN power stations. Best insurance against power outages I can think of. One for my Fridge and one for my small chest freezer. Another reason to have a VTOMAN is for travel. I feel very independent with this form of power.

After purchasing a Vtoman 600 portable power pack after trying the pack we found it did not come up to our expectations on batterylife time specifications and decided to return the product. Have to say the reasons for 5 stars was Vtomans after sales service as all our correspondence was dealt with promptly and efficiently. They collected the item which was an issue for us due to the weight which would have cost alot of money to send back. We had no worry regarding this as Vtoman sent a courier to pick up the battery pack leaving us with a receight of collection. Having purchased this through Amazon were informed by Amazon that the money would be replaced straight back into our account which was done within 3 days. Having read some bad reviews about Vtomans after sales service we can 100% say they were a pleasure to deal with and would have no hesitation in dealing with this company in the future. Many thanks from a very satisfied customer.

As advertised.

My experience has been horrible. The tracking link provided in an email after my purchase is a link to vtoman website which stated no updates yet and to check FedEx site for more information. I contacted FedEx and they told me that this tracking number doesn't exist in their system. I then contacted vtoman customer support for help and they advised that my packages were shipped via UPS. Unlike Amazon or Ebay, I was never sent a message that my packages had shipped, were out for delivery or had been delivered. I contacted my local police and filed a report that my packages had been stolen, and vtoman customer support is saying there is nothing they can do despite the gross negligence on their part of not notifying the customer.

VTOMAN fail to disclose that the way they have designed their extension batteries to charge/discharge, in conjunction with their powerstations, fundamentally damages both. When my powerstations and extension batteries arrived, I initially read the manual, which states that you should not charge the batteries over 90% or discharge them below 10%, because doing so damages them and reduces their operational lifespan (standard advice for Lithium Ion batteries). However, the way that VTOMAN have designed their powerstations to work with their extension batteries, is that the powerstation has to charge to 100% before the extension battery will begin to charge. Conversely, the extension battery will have to discharge to 0% before the powerstation begins to discharge. This means that there is no way to use their extension batteries, with their powerstations, in a way which does not damage both. Seeing as the extension batteries cannot be used without the powerstation, this forces you to use them in a way which damages them. I raised this concern with VTOMAN customer services and they have agreed, in writing, that this is a technical limitation in the design of their product. I asked for the extension batteries to be returned, because they are essentially useless to me (why would I want to use them and damage my powerstations, I might as well have just bought extra powerstations so I can charge/discharge them correctly). VTOMAN demanded that I pay the return shipping fee for the extension batteries. When I pointed out to them that failing to disclose this technical limitation, at the time of purchase, constitutes miss-selling under UK consumer protection law, and that this means that VTOMAN is responsible for the cost of return shipping, they ghosted me. Unfortunately, it is not worth the money to raise a legal matter against VTOMAN over this, so I am stuck with two useless extension batteries. I should have just bought Bluetti powerstations. VTOMAN are continuing to sell these extension batteries without disclosing this fundamental technical limitation, even though they are clearly aware of it. My advice to VTOMAN is to be honest with pepople and disclose this limitation on the product page. Many people would not buy these extension batteries if they were made aware of this limitation. This is your legal and ethical duty. Edit: In response to your reply, In your manual you state "When using the battery every day, it is recommended to charge the battery to about 90% when charging, and leave about 10% when discharging." This is standard advice for Lithium Ion batteries. For example, Fireboard state: "Complete charge cycles can deplete the life span of the battery. Generally, keep the battery charge between 20-80% before it drops to very low levels, and avoid a full charge. Full battery discharges should be avoided since they can reduce the long-term reliability of the battery as well as lead to capacity loss." In order to charge one of your extension batteries, the power station must be fully charged to 100%, thus forcing me to violate the recommended best practice (by both the industry and you specifically) and therefore harm the power station battery. In order for the power station to begin discharging, the extension battery will have to discharge to 0%, also forcing me to violate recommended best practice. This is an excerpt from communications I've had with you: "You raise a valid point - the user manual does clearly state the recommended practice of charging LiFePO4 batteries to around 90% and discharging to around 10% for everyday use, in order to maximize their lifespan. This is an industry best practice that we should absolutely be adhering to. Unfortunately, as I mentioned in my previous response, the design of the Flashspeed 1500 and extension battery does not allow for this manual control over the charging and discharging levels. The power station is programmed to charge the internal battery to 100%, and the extension battery will discharge to 0% when powering the Flashspeed 1500. So in this case, you are correct that using the two units together inherently risks the longevity of the batteries, as they are not being charged and discharged within the recommended 90-10% range. This is a limitation of the product design that we are unable to overcome with the current hardware and firmware." You should put the above statements on the product page of your extensions batteries, so people are fully aware of what they are buying Finally, I did not but from a third party; I bought directly from you!

I purchased the X1500 in Australia, and within just six months, it has become completely useless and won't charge at all. There was a burning smell and smoke coming from the battery, which nearly suffocated me I am frustrated about why this company included a manual and paper with the customer service email address in the package. I sent an email to Australian Customer Center a month ago, and I am still waiting for a response. While I can at least get in touch with the U.S. headquarters, it takes 3 to 5 days to receive a reply. And in the end, they ignore my contact because it's not their responsibility. I have been trying to resolve this issue for over a month now, yet there has been no resolution. I have searched all over Sydney and cannot find a single repair center. I regret spending $1000 on a product from a company that provides such poor after-sales service and customer support. This experience has been extremely disappointing.

all went well
