STANLEY SS4LS Lithium Ion Power Station Jump Starter and 8000mAh Portable Power Bank: Dual 3.1A USB Ports, Battery Clamps

I purchased 3 of these so far. I recommend this product for everything. I have used it camping, for my car starter, and cell phones out in the woods and yes I forgot to recharge it after sitting in my car for 4 months in the winter. My battery was dead in a store parking lot. I got out the Stanley in the back of my car put it on my battery cable and da da. started right up did not even have to wait for the charge. This is a great product to get your first time drivers and keep them safe from being stuck somewhere. My daughter and son have both used them. Awesome gift also.

I have jumped motorcycles, 4 wheelers, and vehicles with this little jumper. I gave my old one to my brother when I bought this one. Does not take long to charge and battery lasts longer than expected. I take it on trips, or just use around the house. Would definitely buy another one!!

I was wary at first that such a small device could jump start a pick-up, but I was pleasantly surprised . I jumped my Dodge Ram 1500 V6 without a problem. It's lite easy to charge (A full charge takes about 6 hours). When you get it, you will need to charge it to full charge before jumping your vehicle . It has lights on the jumper cables that tell you if you have a good connection and it comes with two USB plug-ins for charging phones, tablet, etc.. Stanley says it will hold up to a 90 percent charge after a year, but recommends a recharge after 3 months of non-use. It also has a handy LED light on the back side. So at $49.00, it's a pretty good deal, as most Lithium Jump Starter run $70 or more.

Works great for me. You have to remember to charge it monthly or so (no battery keeps a charge indefinitely). This charger works great for temporary low power battery issues such as winter cold, or if you accidentally left your lights on overnight, but it isn’t meant to start a completely dead battery. In addition it can charge your phone or tablet with ease.

I used a friends jumper unit for jumping a car and it worked great. So I order one for myself, but unfortunately, either not all of the pieces for using the battery or wrong jumper cables were in the box. The unit is useless with the correct jumper cables. So far no help from Stanley, the manufacturer, on getting this rectified.

I should have bought one of these a long time ago. This thing really comes in handy in all sorts of situations. If you don't buy this particular brand / model, get one somewhere else, and keep it in your car. It should be a part of an emergency kit in every automobile.

During a 2022 Christmas shopping day. We were parked next to a double cab Dodge Ram pickup. Apparently the man’s battery had died. We watched him restart his pickup with this. We were like wow that things handy. Rolled window down to inquire what he used. Husband had to have one.

Excelente producto!!
