Question: 6 c batteries or 4 D? I am confused . Thanks!
Document: Comfortable and worth it. it uses 6 c 1.5V batteries. The instructions said 4.5 which threw me off but I love it!! Good buy!
However I am giving only 3 stars because the description is wrong on the amazon site. The hand pump needs 6 C batteries and not 4 D batteries.
This is my first air bed mattress and I must admit I am totally impressed. The only thing wrong is that it uses 6 &#34;C&#34; batteries and not 4 &#34;D&#34; batteries as advertise but will highly recommend to anyone! !
I have no issue with the airbed itself - seems to work just fine (now that I have the right batteries to inflate it). The product title and description INCORRECTLY state that the airbed requires 4 D batteries. After receiving the package in the mail, I found that it actually requires 6 C batteries. Amazon, please update this product title and description!
My son likes to sleep it though he also said it smells.It is said on net that 4 D batteries needed for the pump. I bought and tried but realized that the real pumple need 6 C batteries. It is lucky that the store exchange the batteries for me. So you better buy battery after you get the pump and read carefully the size of the batteries required.
I ordered the airbed and have yet to inflate it because under the product description, it said the battery pump takes 4 D batteries, which they then said I could add at checkout. I just opened the pump and it takes 6 C batteries. I put 6 I had here in and the pump didn't work. They may be old. I will buy batteries tomorrow and check it out.
I ordered this product to use for some friends that were coming in town, and in the product description it said that the hand held battery pump uses 4 D-cell batteries, so I also ordered 4 D-cell batteries. When the mattress came, I found out that the hand help battery pump actually takes 6 C-cell batteries, so I couldn't even use the mattress for my friends because we had no way to blow it up.
BECAREFUL. This mattress actually comes with the pump that requires 6 each C batteries but description shows 4 each D batteries.C is extremely difficult to find and in most cases more expensive than D.
I bought a ton of D batteries here because the description says it needs them, but it needs C batteries instead. I wasted $13 on batteries that I'll never use. Thanks, Amazon.
The mattress is great! The pump suuuucks! 6 c size batteries!? Are you kidding? Wasteful and expensive. Needs a plug pump! !
