Office workers and gym-goers looking to save money on costly smoothies and protein shakes will no doubt want to pay attention to Ninja's latest deal. Fans of the brand have been raving about the Blast Cordless Portable Blender - and it's not hard to see why.

An easy way to incorporate more fruit in your diet, the blender-slash-bottle makes smoothies on the go. It's fitted with a rechargeable blender so you can simply stash your favourite smoothie or protein shake ingredients in the morning and blend anytime in the day when it suits. It can also be used for frozen cocktails for the adults, and milkshakes for the kids when the sun is shining.

The mini blender has a rechargeable USB-C base which has a big enough battery to power 10 blends per charge. Plus, the blending cup has a large 530ml capacity and leakproof lid which means you can stash it away in your gym duffle, work tote or handbags without running the risk of any spillages.
