Time will tell how well the jump starter’s battery holds a charge

Very good keeps me charged in more ways than one

Secondly... I had not had the unit long enough to know how well it would stay charged over time

I received this product last week, but I had Not used yet to charge a car battery, however I used as a power bank to charge my cellular phone, is working great with a good charging capacity

USB C for fast charging

I like the portability and power available to start my car battery in the event that my battery no longer carries a charge sufficient to start my car.

Great portability and charging possibilities

Looks great is charging now all looks well

Seems to hold a charge well, unlike other jump starters I've owned in the past

Fortunately I have yet to use it to jump my truck, but have used it for charging phone and its worked wonderfully.

well, it becomes kind of useless if the charge is not available when you need it

It came charged to 76% and ready to go

Nice rigid casing and fast charging feature a plus.

hasn’t lost any quantifiable charge yet

Convenient usb-c charging.

Still preferable over a proprietary charge port

Easy to use, compact, good charge right out of the box

Fresh out of the box it came 83% charged

Nice rigid casing and fast charging feature a plus.

Rapid charging

Product arrived in great condition charged to 88%

It is filling Easy use and easy charging

Shows 81% charged so ready to be used if needed

USB-C charging is also very convenient.

Usb C for fast charging

Very fast charging.

To name some that stand out to me: the jumper connector shield only protects that single port (I hate the other ones that have one giant sleeve to cover all of the connections), all the ports are easily accessible (and not blocked by handles or unnecessary features), cigarette barrel adapter is included (instead of not being included or being built straight into the device), LED display with troubleshooting codes directly on the jumper connector, no "Boost" button necessary, fast charging works great with my phone, seems to hold a charge very well (we'll see in a couple of years how it holds up)

I love that it has a usb type c for fast charging my iPhone 11 pro and the battery capacity as well

Love the usb-c charge and all the other features

I had minor issue with my jump starter that only charge to 99%

Screen is small, charge % easy to read but other status indicators are tiny, same with clamp display.

Heavy duty, portable, long lasting charge

Have already used it to start vehicle twice and still has a great charge

Feels nice and solid, but should include a charging block as well.

Best feature is that it had a USB-C port for fast charging any device as well as itself

Doesn’t have charging adaptor, not a problem for me.

After checking voltage with the multimeter, the battery is just fine (16.5V at starter port) and takes a charge no problem

so charging is slower and charger gets hot at full load

Powerful, USB C charging, good price

Easy charging

This makes me feel confident that it will always provide enough charge to a dead battery

Looks well made, came with nice case and 84% charge.

I read one customer here complaint about overheat of the wall charger while charging, mine charged to 97% and the charger stayed cool

Battery charger controller is showing wrong charge status, dropping from 100% full charge to below 60% and the 0% even though cells still have charge.

The QC 3.0 usb output is great for powering quick charge devices like my hotspot

Holds a charge and works as expected

Well, sure enough , it indicated that it did not have enough charge

I love all the extra features such as flashlight and phone charging .

This has a fast-charging usb-c port, which is the way of the future

I really like that it holds a strong charge

Worked perfectly on a 2012 mdx , best part it came 80% charged.

But uses USB C, just like my phone

Great product that works exactly as it is intended to be used!

So I gave the battery sufficient time between start attempts to cool down as per the instructions

As a side benefit, I can use it to power my CPAP for about 6 hours if need be, as well as, charge phones, iPads...etc.

I hope it works as it should when I need it.
