Review on Vanzon Climber-Z 30W Bluetooth Speaker: Portable, Waterproof, Super Powerful Bass - Perfect for Parties, Travel, Home & Outdoors! by Michael Patilla

I bought this small portable Bluetooth speaker for a trip to a lake near Yellowstone National Park. I was pleasantly surprised at how small it is (see picture next to my iPhone 11 pro max). It was easy to get through airport security (you can't put them in your bags due to TSA rules, but you can take them in your carry-on). to travel . We used a boat on the lake and of course in a rented cabin. it certainly didn't disappoint. Pros: 1- Small, light and has a hook for hanging 2- Fast charging with USB C3- Great water resistance (no we didn't dive in the lake but as the boat moved water splashed everywhere, this speaker held up and stayed like new) 4- Decent Bluetooth range 5- Powerful Cons: 1- It doesn't have device (phone) charging options like other portable Bluetooth speakers, but they tend to be much larger. All in all, my friends were impressed with the performance of this speaker and ended up getting it for their personal use after the trip.
