The RPB27 is a portable Bluetooth speaker that is the perfect size and power. This speaker is big enough that our engineers were able to get the speaker to produce 20 watts of power with huge bass! It is small enough to bring it with you camping, hiking, or anywhere else. The speaker is extremely rugged! It is shockproof and IPX6 water resistant. This means you can throw it around and bring it in the shower and the speaker will never break!
There may be some similar looking Bluetooth speakers on the market but this is the only speaker at this price point that is rugged, water resistant, and has huge power with huge bass!
Below is what makes ours better:
IPX6 Water Resistant
The RPB27 is water resistant, or splash proof. You can take it with you into the shower, or by the pool side. In reality this speaker can be thrown into water without getting damaged, but we are rating it as splashproof. I tested it in the shower and put it under the showerhead with no problems.
Amazing Power with Bumping Bass!
This speaker puts out a huge 20 watts of power. Its louder than any other speaker I have tested that was similar in size. I’ve tested many Bluetooth speakers, and this one sounds better than speakers that are way bigger! Our sound quality is amazing. This speaker has great bass and crystal clear highs with a distortion rating of less than 1%. What makes the bass so loud is that the speaker has a passive radiator to enhance the bass. That basically mean the speaker has an extra subwoofer built in that focuses on playing back bumping bass!
Built with 100% ROHS Silicone & ABS, this enclosure design delivers top of the line sound quality. It includes rubber feet for great sound when placing the speaker on any hard surface. The design mold is an exclusive Rockville design!
Huge Battery Life
This is a big advantage with our unit. We use a high quality original 1,000 mAH battery rated for 18 hours of playback with a charge time of 4-5 hours.
Amazing Bluetooth Integration
This uses the latest and most reliable Bluetooth chip. It has Bluetooth 4.1 technology with enhanced data rate and a range of 40 feet! This guarantees a crystal clear signal even when you are away from the unit. Pairing your phone or other Bluetooth enabled device is super easy! There is no password required. Simply turn the unit on and it automatically connects to your device.

About Rockville Quality Control Procedures:
The Rockville brand stands for Quality, Innovation and Value. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville products are backed with a full 1 year warranty, though it is unlikely that you will need to use the warranty.
