【認定整備済製品】ALLPOWERS大型ポータブル電源R3500(3168Wh/3200W)

Dear ALLPOWERS customer support representative

Thank you for your help.

We will contact you about the ALLPOWERS R3500 portable power supply that we purchased as a used product the other day.

Although it has been less than a month since the purchase of this product, we have determined that "there is a major problem with practicality" for the following reasons, and we strongly request a refund.

■ Details of the problem

Battery life is significantly short Even if it was charged up to 100% with an AC input, between around 18:00 in the evening and around midnight, about 69% was consumed for TV lighting alone. After that, even though I was supplemented by inputting AC again from the S2000 portable power supply, I didn't use a TV, and I only connected the phone and TV recording equipment, and **at 5 o'clock the next morning, the battery level was 0%** This situation has occurred twice.

There is a suspicious point in the full charge display In the daytime AC input (from 11 o'clock), even though the specification says "fully charged in 2 and a half hours", it was 100% displayed in an hour and a half. However, even if you check the power company's usage monitor, the daily usage has not reached 3kWh, and it is extremely doubtful whether it is actually stored.

Performance that cannot withstand actual use This portable power supply was purchased for elderly families (caregivers) as a "lifeline" to operate nursing care beds and minimum household equipment in the event of a power outage. However, in the current situation, it is just a heavy lump of lead, and it is completely useless in an emergency.

■ Request for a refund

It has only been within a month since the purchase, and in a situation where the performance is so poor, the specifications do not match, and the actual use is not enough, it is not enough to return or exchange.

We would like you to respond with a full refund, so please reply as soon as possible.

I can't use it with peace of mind at this rate, and there's no point in buying it, so I'm very disappointed.

Thank you for your understanding and response.
