Review on MEGAWISE Car Battery Jump Starter - 1500A Peak 16800MAh Portable Power Pack For Up To 7L Gas Or 5L Diesel Engines, Dual USB Outputs, Auto Battery Booster [2021 Upgraded Model] by Jayt Shields

Easy to use: The clamps have the polarity etched on them so you know where to attach them. All you have to do is clamp it on and start your car. The built-in protection features should stop you from reversing the polarities of the clamps.The battery is good enough for multiple starts.There is a small LED on the cables that gives you information including your battery's voltage.There are only 2 things stopping me from giving it 5 stars:1) I haven't used it for long so I don't know how durable it is. I would feel more confident in this product after using it for a longer duration.2) It could have been a bit smaller. Right now it is too big for my glove box.
