I recently purchased the Outdoor Master shark 3 mini, this is my honest review hope this helps.
The pump itself is incredible and the hype people give them is 100% justified, on my first use I've inflated a 10'9"x6"x32" wave drop stitch SUP to 15psi which was rapid in 6 minutes and a 2 seater Sandbanks explorer drop stitch kayak all 3 chambers to 12psi in 5 minutes and i hadn't even used one bar off the battery, i also deflated them with the pump to make sure all the air was out and after that i had just used my first bar of the battery. This pump is rated to inflate 5 plus SUPs to 15psi consecutively without stopping, and honestly I believe every word of it after using it for the first time, this is because this pump has a dual motor system which is what gives you a rapid inflate and believe me it is quick, a unique feature to this pump is it's cooling system which allows it to do five SUP/kayaks consecutively without overheating something you just don't find in other pumps. This is an absolute powerhouse, incredibly easy to use also has three presets settings for inflatable mats, paddle boards and inflatable kites for your paddle boards, one thing I do like is the fact that you can set this in point one PSI increments not just a half PSI at a time like most pumps are.
If I had anything bad to say about this pump it would be these two things, firstly it is a very loud pump I've got to say but it is a rapid inflate so I can understand why, you have to give and take at the end of the day and the trade off in inflation speed against the noise is justified especially as this has the new dual motor, my biggest niggle with this is for the price you pay which is expensive I will be honest you do not get any sort of case or bag to store your pumping with the attachments and hose, which did frustrate me I will be honest, for something this premium and this high price it really should come with a carry bag or carry case, I certainly do not want this rattling around in my kayak bag or my stand-up paddle board bag with the attachments and the hose rattling around either getting damaged, this is something I will be bringing up with the company. But apart from that this i give this pump five out of five all day long it is an absolute beast and worth the money 👍🏻👍🏻👍🏻
(I have been in touch with the company about a carry bag etc and at the time of writing this they have told me they have just released a Caribbean to purchase for this pump, which in the UK with the VAT tax on comes to around £19, I have told them that is great news but I still stand by what I said and for the price you are paying for this pump this carrier bike should be included as standard, when you are paying near enough £160 after VAT tax this should be included no questions, a customer should not have to be purchasing a separate bag. I have to go out straight away and find a small rucksack one that wasn't too big to put this in just to keep it safe and my puddle board and kayak safe in their bikes but of customer should not have to be doing this as this should be included. It takes nothing away from the pump itself this is honestly an animal and I could not believe how fast the inflates paddle boards and kayaks etc and it's lightweight and not too big, do keep an eye out on their website because they have discount offers all the time, you just need to be aware that the price you see will change depending on your country when you get to the basket to finalise your purchase and it is due to the countries tax/VAT which has to be added it's not the company's fault it's the country you're in that causes this problem)
