Zempire  Monstapump Air Mattress Pump

I highly recommend purchasing the pump with your mattress. It made setup incredibly quick and easy. The mattress was fully inflated in about two minutes with virtually no effort. The pump was simple to use, powerful, and took all the work out of inflating and deflating our camping mattresses. After a long drive to the campsite, the last thing I want to do is spend time manually inflating a bed, and this pump made the process effortless. It also made packing up at the end of the trip much faster. If you're investing in a quality camping mattress, do yourself a favor and get the pump too. It's absolutely worth it.

I tried to charge this device multiple times, to include the instruction recommendation of 8 hrs or overnight. It never turned on. Not once. If you’re okay that it’s hit or miss that the device won’t even turn on or not - go for it, and keep the receipt, box, and everything else pristine ready for return (I regret not doing that). If not, I highly recommend purchasing a different pump.

Pump would not accept a charge out of the box. I plugged it in and red light displayed to indicate charging, but 24 hours later it was still dead. I returned it.

I've ordered 6 other types (similar sized rechargeables) thru Amz, this is the one I'm keeping!! strong enough to fill my 10" queen air mattress to the firmness i like, none of the others from Amz could. This was ~2x the $$ but I am very pleased, nice carrying pouch too. The only negative, a VERY minor one, is the trigger protector dealio, it has a hardshell case...but I'm nit picking. This can help take some of the effort off inflating my kayak, use to get 80% finish with the handpump.

Small, yet stronger than my bigger pump. Strong enough to deflate my Zempire Monstamat Twin Self-Inflating Mattress back to original size. So far it's been great.

When it works, it works great with the mattress. But all of a sudden it’s just stopped working. Hopefully I can return it or exchange it for a different one.

I have both a single and double matters, the battery on the pump is only just able to blow both up. If you are not carful there might not be enough to do both. Should note this is true for both inflating and deflating. On a couple of occasions, the battery has died before I could do both mattresses. To make matters worse, you need to fully charge the pump before it will work, so when it dies your waiting an hour+ before you can finish inflating/deflating.

We're on our second pump. First one wouldn't charge, and the second one the battery dies when the bed is about half inflated. So you have to wait for it to charge up again. We're looking at another pump now as this one is rubbish.

Picked up the queen mostabed to try out and then the monstapump. And the pump was a dud charged over night still dead. Took back and got a new one and it worked. Gave poor review due to the fact it should work and it wasted two hrs of my time driving back and forth to REI (I know it isn't Rei's fault but zempires) and honestly it should come with a high $$$ air mattress.

Money grabbing jerks zempire is for charging 400 bucks for a twin camp mattress and not including the pump!
