amp jump starter may not be able to revive a totally depleted battery that’s been idle for months but is useful for roadside emergencies. As we have already tested a lot of jump packs in this range I was extremely excited to test of the 3000A jump starter. The large LED light provides around 400 lumens and is rated at 30 hours with a fully charged battery. For motorcycles, dirt bikes, or ATVs, you need to consider the battery clamps on the jump starter because if they are large, they might not fit on the (usually small) battery posts on your motorcycle or ATV.

As an added bonus, I’ve had the case under the back seat of my truck for weeks and it seems no worse for wear. I used a clamp meter to measure the amps while cranking and took burst photos using my iPhone to record the amperage readings. We tested the air compressor mode as well, and this works well – but this device won’t compete with a high-quality tire inflator or one of the best portable air compressors on the market. Stanley claims that this jump starter can provide 700 peak cranking amps to jump starter your vehicle.Just to give you an example of the battery capacity of the JS3000, a fully-charged unit can run the flashlight for more than 30 hours! it’s not so heavy one person can’t carry it, but it’s noticeably heavier than the other jump starters we tested. I will show you exactly how I tested these jump starters and which of these jump starters are my favorite. In 2008, Clint founded Pro Tool Reviews followed by the landscape and outdoor power equipment-focused OPE Reviews in 2017.

It also has a handle, which can be helpful when you’re in a stressful situation or if you want to lash the case to a hiking bag to bring the unit on a hike as a remote power source.

I disconnected the battery on my truck (as the battery was perfectly ok) and hooked this jump starter to the vehicle.To check the safety features of each jump starter I did a really stupid thing: connected the black clamp of the jump starter to the positive post on the battery and the red clamp of the jump starter to the negative post on the battery, on a parts car. Its type C bidirectional charging includes PD45W output, PD45W input, and provides fast charging for devices that support PD protocol, such as laptops, cell phones, and more. Working on a myriad of feature films, Clint honed his skills as a dialogue editor, foley editor, and sound designer. Our carbon pile tester immediately registered the JS3000 when we used the boost mode, which is able (for a short period of time) to deliver well over 12. This jump starter also checks my safety checklist with reverse polarity protection, overcharge protection and short circuit protection.

This charges via micro-USB (which is a little slow) and comes with a wall adapter and a cigarette lighter adapter. The indicator light should be green – if it’s red, that means the poles are reversed (which is a great design feature for those that aren’t as familiar with jumping a battery). The JumpSurge2000 is a must-have device for anyone who relies on their vehicle for their livelihood. The TOPDON JS3000 portable jump starter makes it easy by including electronics that warn you if you have anything mixed up. Though a general rule of thumb is that higher peak amps are better, knowing a jump starter’s peak amps is usually less helpful than knowing it’s CA or CCA.It has really strong metal clamps that don’t flex when clamped on the battery post and also has reverse polarity protection. It charges through USB-C, and there are two other USB-A ports for charging other compatible devices. It is broadly comparable to other similar-sized jump starters though with an above-average power output. This jump starter also tells you the battery voltage so it is easier to diagnose if your truck’s battery is dead or good. The Boost X series stands out among other NOCO jump starters because of cold cranking capacity and quick charge times.
