Review on 🔋 FLEXTAILGEAR MAX Pump 2020 Portable Air Pump – Rechargeable with 3600mAH Battery, Quick Inflate/Deflate for Air Mattress, Pool Toys, Floats, Swimming Ring, Air Bed, and Vacuum Storage Bags by Rob Bishop

Inflates my 84 x 24 x 4 inch Big Agnes air mattress in about 60-70 seconds. With various attachments, it fits most mattresses, even inflation valves that unscrew the cap on the corner of the mattress. As for the charger, it charged my phone up to 69% and then stopped charging, but worked great for a week until it blew up. We inflated three mattresses at three campsites and used it to deflate one mattress in a single charge. I tried charging my phone multiple times but it only charged for about 5 seconds and then stopped so I only got a decent charge from it. I can recommend it as an inflator, but not as a battery for charging electronic devices.
