Manufacturers are adding in other features and options into portable battery packs in hopes of setting them apart from the rest. We had a chance to check out the new Cyntur JumperPack mini – a 12,000mAh Lithium-ion portable battery pack which also includes a flashlight and the ability to jump start vehicles, certainly a handy feature to have. So how does this new entry into the market fare? Check out our thoughts in the Cyntur JumperPack mini review.
Specifications
The JumperPack mini features the following specifications:
- 12,000mAh Li-ion battery
- 5V/2.1A USB port to charge smartphones and tablets
- 15V/1A DC input
- 200 lumen LED light with torch and strobe (S-O-S mode)
- 250 cranking Amps of starting power
- Holds charge for up to 1 year
- SmartJump Technology that prevents reverse charge, reverse polarity, over-current and short circuit
- Weighs 0.9lbs
Design
The JumperPack mini is roughly 6″ x 3.3″ x 1.3″ and is housed in a hard plastic shell and looks like something you’d find in a mechanics toolbox being painted black and orange. The top of the battery pack has a function button which you press to turn on USB charging, check the battery, or turn on the flashlight. When turned on, a series of 4 lights light up indicating how much battery charge is left in the unit. One side of the device features a grooved finish which works quite well as a grip when holding it in one hand. The front of the JumperPack Mini houses the flashlight and a flap which covers the connectors for the jumper cables, USB charging port, and the charging input.
The battery pack feels quite sturdy and the cover at the front seals shut tightly, which is a must considering it is also rated IPX3 for weatherproofing. The booster cables fit in very snug and require a bit of effort to push fully in, ensuring that they won’t just wiggle out during use.
Performance
So how does the Cyntur JumperPack mini perform? My primary place of testing was at a local car dealership and the lot manager was amazed at the vehicles it could boost given its small size, often without any delay. Vehicles which had completely drained batteries turned over immediately once the JumperPack mini was connected. Out of 13 vehicles we tested, there wasn’t one that it wouldn’t boost and that included a V8 Range Rover and a V6 Diesel Jeep Grand Cherokee. Cyntur claims it jumpstarts up to 8-cylinder vehicles, and it does so without issue as can be seen in the quick video below.
Battery Life
While we can’t test Cyntur’s claims that the JumperPack mini will keep a charge for a year, the battery life on this power pack has done exceptionally well so far. When I first unpacked it, the battery pack was indicating a full charge as it comes pre-charged. Two days later it was still showing a full charge and even after boosting a couple vehicles, the charge indicator lights still showed it being full. It was only after boosting five vehicles and charging my phone once that it dropped to indicate 75% charge left. After boosting the aforementioned 13 vehicles and my Nexus 5 from 15-100% and 28-100%, the pack is still indicating 50% battery life.
The JumperPack mini is supposed to fully recharge in 4 hours, and it took a little over 2 hours to recharge it from 50% back up to 100% so I’d assume it would fully recharge from having no charge to holding a full charge in about 4 hours.
Price/Value
The Cyntur JumperPack mini costs $99.99USD, and a quick search of other 12,000mAh portable battery packs indicate that they retail for around the same price when not on sale. The JumperPack mini has a huge leg up on the competition though as it not only charges your phone and tablet, but can jumpstart your vehicle if needed and triples as a flashlight and emergency strobe. Not only do you get the battery pack, power adapter, and jumper cables, but Cyntur includes a pretty nice storage/carrying case for the pack and the rest of the accessories it comes with. Based on the performance and what it can do, the Cyntur JumperPack mini is a great deal for the price.
Wrap-Up
Even though the Cyntur JumperPack mini is marketed as a portable battery for boosting your vehicle in case of a dead battery, it is a perfect solution if you are looking for a portable battery pack to keep your electronic devices topped up. It boosts four, six, and even eight-cylinder engines – both gas and diesel – without any issues, and could be a real lifesaver with the included flashlight/emergency strobe. This battery pack is priced right, performs well, is lightweight, and has multiple uses.
The Cyntur JumperPack mini is available from Target stores in the U.S., or from Cyntur’s website.
