Review on Zacro Portable Electric Air Pump 6000mAh Battery | Quick Inflation & Deflation | USB/12V Outlet Powered | 3 Nozzles for Mattresses, Lounger Sofas, Pool Floats, Airbeds by Julie Lemus

This thing works amazingly well. I've inflated and deflated my Queen air mattress many times, found and repaired leaks, and according to the LED indicators, the charge has never dropped below 50%. Then it is fully charged via USB in a few hours. A little noisy but bearable. The motor is so powerful that it actually produces a noticeable "bump" of reaction torque at startup. It comes in a very nice case with molded compartments for accessory attachments. The 17mm nozzle fits my INTEX mattresses. I plan to use this for camping. I'm sure it works well, but of course I can't comment on long-term reliability yet. But it is a very good product and I am completely satisfied with it. even pleasantly surprised at how powerful it is! When choosing, what struck me compared to many others is that it has a 6000mAh battery; which is worth more than the price if you try to buy these batteries separately!
