This graphene battery pack charges incredibly fast

Update November 24 at 09:30 ET: The original Indiegogo campaign ended (with all contributions refunded) and reinserted here. The problem, according to Elecjet, was due to a recent change in the legal designation of the company from LLC to Corporation, which unexpectedly changed its tax ID and the campaign’s ability to process payments. Unfortunately, the delay due to the relaunch means that Elecjet can no longer guarantee shipping before Christmas.


Elecjet’s new Apollo Ultra battery pack uses the graph to dramatically speed up charging. Yes, the graph, the miracle material that has long promised to change the world, allows this 10,000 mAh laptop battery to charge from zero to full in less than 30 minutes, about five to six times faster than a conventional powerbank of the same capacity. Plug it in when you wake up and the Apollo Ultra should be fully charged when you leave the house.

Graphene is a highly conductive lattice of carbon only one atom thick. Pure graphene batteries are still too expensive to mass produce, but the material can already accelerate the charging properties of traditional batteries when applied to a composite electrode. That’s the approach Elecjet is taking with its new 10,000 mAh (40Wh) battery, launched today on Indiegogo for $ 65.

In addition to a faster charging speed, Elecjet says the Apollo Ultra will last for more than 2,500 charging cycles before the battery drops to below 80 percent health. It’s about four to five times longer than conventional lithium-ion battery packs, which would be good for both your wallet and the environment.

I can not imagine testing the lifetime claim, but Elecjet sent me a review sample of the Apollo Ultra to validate the improved charging speed.

In short, the Apollo Ultra charges fast – incredible fast, as Elecjet claims.

The Elecjet Apollo Ultra is a lithium-polymer battery that has been enhanced with the proprietary battery technology of Real Graphene USA. It is equipped with two USB ports: a full-size USB-A and a USB-C PD 3.0. The USB-C port accepts an input of up to 100W to quickly charge the battery pack. This port is then capable of 65W out, making it powerful enough to charge many USB-C laptops. It supports Samsung’s PPS fast charging technology and holds enough energy to charge a typical phone two or three times. The USB-A port is capable of 18W max output.

Fine, but it’s the battery charging speed we’re all here for, and Elecjet says the Apollo Ultra will charge from zero to full in a very impressive 27 minutes when connected to a powerful 100W wall charger.


Time-lapse compares the Elecjet Apollo Ultra charging speed with a conventional powerbank with the same capacity.

My review unit repeatedly charges from zero to 99.9 percent in 27 minutes using a 100W GaN charger (sold separately for around $ 50) provided by Elecjet. It then took another 90 seconds to report 100% on the battery display. Elecjet says this is a minor bug and the battery is “99.999 percent” charged after 27 minutes. Elecjet Apollo Ultra otherwise charges linearly and reaches 25 percent in 6.5 minutes, 50 percent in 13 minutes and 80 percent in about 21 minutes.

By comparison, I connected the same 100W charger to a 10,000mAh lithium-ion battery that I recently purchased on AliExpress for about $ 20. It took over three hours to charge from zero to full. It supports Elecjet’s claim that the graphene – enriched Apollo Ultra charges five times faster than conventional battery packs.

I also charged the Apollo Ultra battery from my MacBook’s less powerful 29W charger. The power bank is charged from zero to full in 74 minutes. It is much slower than you would expect from the weaker charger, but still more than twice as fast as the AliExpress battery connected to the 100W charger.

Things got a little strange when trying to charge two devices at the same time from Apollo Ultra. My MacBook reported that it was charging at 65W when connected to the USB-C port. It then dropped to only 5W after I connected either an iPhone X or Oppo Find X3 Pro to charge simultaneously from the USB-A port. The Indiegogo campaign’s FAQ claims that Apollo Ultra’s “87W output power will be split between the two devices”, so something seems wrong.

The Apollo Ultra I tested was only slightly heated in the approximately 20 times I have charged and discharged it completely, while the slowly charged lithium-ion reference battery remained cool throughout. “Heat” is commendable given that the Apollo Ultra draws more than five times as much power and talks about the graph’s efficiency in dissipating heat. Elecjet tells me that the Apollo Ultra is equipped with eight safety features and that the UL temperature test never exceeded 42C (107.6F).

The Elecjet Apollo Ultra is also more chubby than my reference battery despite having the same number of electrons. This is due to the larger power module required to handle the higher input and output effects. Although the size of the device does not change for the product shipped to Indiegogo backers, Elecjet tells me that the next-generation power module should allow its future hybrids to match the size of its slower charging predecessors.

Chinese phone manufacturers are currently involved in their own fast charging race. Xiaomi’s new 11T Pro has a 5,000 mAh battery that charges from zero to 100 percent in just 17 minutes with the included 120W charger. But that battery is a dual-cell design that allows both halves to charge simultaneously. That’s fine for $ 500 + phones with sophisticated chipsets that are not limited by the limitations of USB-C PDs. Nevertheless, the Elecjet matches the 17-minute charge with its second graphene-enriched battery pack, the 5,000 mAh Apollo Traveler.

That’s right- Apollo Ultra is not the first graphene battery pack to be purchased. In addition to Elecjet’s offerings, Chargeasap makes a range of hybrid battery packs, including a monster- $ 299 20,000 mAh battery pack, which is also loaded with graphene, with multiple ports only, a wireless charging surface and higher 100W output. The company says it will charge from zero to full in 70 minutes, which sounds pretty much right as it holds twice as much juice.

These hybrid batteries are an impressive first step of manufacturers on the road to developing the small, high capacity and environmentally friendly pure graphene batteries, we have been promised.

Until then, the Elecjet Apollo Ultra is priced at $ 65 on Indiegogo right now.
