H50 Jump Starter - 5000A Jump Starter Battery Pack for Up to 10.0L Gas and 8.0L Diesel Engines, 12V Car Battery Jumper Starter Portable with 3.0" LCD Display, Jump Box

There are moments — cold mornings, stalled engines, thresholds between motion and stillness — when the world asks whether you will continue. The HPBS H50 Jump Starter answers yes with an electricity that feels almost mythic. Compact as a secret, fierce as a heartbeat, it sits in the glove compartment like a promise: that dead things can be revived, that silence can be broken, that journeys can begin again. When I first pressed its clamps to the sullen terminals of my car battery, I felt the familiar tension of doubt. But the H50 ignited the engine with a confidence that bordered on the alchemical. Power, clean and bright, rushed through metal and machinery, and the vehicle woke as if from a spell. What I love most is not merely its competence — though it has that in abundance — but its philosophy. It is a device built on defiance, on the beautiful Wintersonian notion that energy is never lost, only transformed. The H50 transforms despair into momentum, interruption into adventure. Five stars. For reliability, yes — but also for reminding me that even in the machinery of our days, resurrection is always possible.

Small, convenient and works!

This device absolutely surpassed my expectations. It has reliably started a 1971 Jeepster Commando that didn’t have enough battery power to kick over. And in 13 degree weather. As a test, I tried it on an old diesel Case Backhoe with a weak battery. It had enough power to get it to hit, but not enough to start. But that realistically is a bridge too far for something this small and portable. Absolutely recommend.

Very good! Charged our dead battery and only used 4 % of its power. It did take a few minutes, but the battery was pretty dead.

I spend a lot of time out in the desert and worry about my car battery dying. The auto club or tow truck would never find me and I fear being stranded. The HPBS H50 seems like cheap insurance. I do wish, however, the clamps weren't so hard on the nipples.

This device has saved me so many headaches. I been having problems with my battery going dead on me. I used it in 20 f weather and my car started up with no problems. It’s nice and smaller so it doesn’t take up much storage room in my trunk. I used it on a 4 cylinder engine.

I was not to sure which Jump Starter I should purchase but I am glad I got the HPBS H50. It came with 77% battery and I charged it fully to 100% before using. The jumper started my car immediately without any issues. It was very easy to use as well. I am glad I have it handy and would definitely recommend it to anyone looking for a dependable and effective jump starter.

Battery was totally dead. I had this HPBS jump starter charged and ready. But my dad got to the jeep first. Im not sure what he tried..I know he has some kind of jump starter and something else? My cameras show me how hard he tried and how long. I was not home at this time. I was told it may just need a new battery. Bummer!! The next day... I was like I may as well try my new jump starter. What could it hurt? Easy hook up. I will say I follow instructions. It did take a little time battery took about 80%or less. I tried twice to start the jeep. The second worked!! This charger performed!! My dad was shocked the jeep was running and haven't had any problems with it.
