Recharging this Charger Fast and Simple
Unit arrived partially charged but I followed product instructions and brought it to a full charge. It charges rather quickly with the charging rate appears to be 8-10 % per hour when plugged into USB 3.x for charging from 120v ac outlet. The product works as advertised and as expected. It started my 7 years old battery in my 2017 Porsche Macan with turbo trim (more battery requirements for turbos). An excellent compact unit that will serve me well for a long time! (Pic – initially charging the unit before operation).

Saved the day with no one else around to help jump
I’ve only used this for jump starts. I can’t comment on it’s other features.I have a 2003 Lexus IS300. The battery was so dead that it didn’t have enough voltage to trigger a battery tender to initiate charging. The only other car at home is an EV.The jump starter arrived 85% charged and I immediately put it to the test. Really simple. Connected the clamps, turned it on, clamped to the battery and jumped like a charm. I only needed to move the car a very short distance so it was inevitable that I’d have to jump it again. A half hour later I gave it another jump without issue.With 2 jumps I used about 15% capacity on the charger. This will stay in my emergency kit from now on. Only complaint is that the digital readout is too dim to read in broad daylight or even in light shade.

Misleading product description; UPDATE Product works well
The product description lists its engine’s jump start capacity at 5l gas and 3l diesel but the product literature and the company’s own website lists the capacity at 4l gas and 2l diesel. I just received the product today and haven’t had a chance to use it so I don’t have enough information to rate its performance. The vehicle I got it for has a 3.0 liter gas engine which should still work with this unit so I’m not returning it just yet but for the misleading info I give it one star.UPDATE: I used the unit on a dead cold battery for my 3.0 liter V6 4X4 Toyota pickup. The unit was charged at 100% and the engine turned over on the first try. I removed it and let the engine warm up a bit then turned it off and tried to restart. The battery had not charged enough so I used the unit again. This time the unit had a 94% charge and again it turned over on the first try. After both jumps the unit still had a 90% charge. I’m pretty impressed with this product so far. I don’t know how long it will maintain this starting power but I would recommend this to anyone with a similar engine. The instructions are not complicated and It’s easy to hook up. Still taking off one star for the misleading product info.

Don’t buy this!
Don’t buy this piece of garbage! It failed me when I needed it most!!!! I had charged it for 24 hours and then kept it in my trunk. The next day I needed it because my car would not start (in 100 degree weather) and it did nothing. What a disappointment.

Great Multi jumper for E350 Benz
Purchased for my 72yr old mother-in-law to use for a few weeks before her car battery was available…. I walked her through the process after watching several YouTube videos about her car and although she was terribly afraid she’d make a mistake, she was able to jump start her dead Mercedes Benz E 350. The size is compact – not too bulky. Easy to store and use. She was able to get several jumps before needing to recharge. The cables are shorter than expected but just the right size to reach the areas in her car. This is a great product.. please follow the instructions to get the most value.

great delivery time, tried once on a 1.6L petrol vehicle and worked fine, battery still at 100%
Amazonian –
Was ok to start 1.6L petrol once, one second use a week or so later, just wouldnât start the car. Then went from 100% to 72% every though the car didnât turn over at all. Turned the jump starter on and off a few times as it failed to come on at all, turned car over it started just, but went from 72% to 0% Returning jump starter for a refund.
