Everything That's Included
Each purchase comes with 1 x Flash power bank + 1 x mesh pouch and instruction booklet. We also offer fast customer service within 24 hours, 30-day hassle-free return policy and 2-year international warranty.
Please note Flash 2.0 does not come included with:
- A wall charger: Can be powered with your existing 100W USB-C wall charger such as the original 15" or 16" Macbook Pro. If you don't currently own a 100W USB-C charger, you'll be able to find our range of chargers here and here.
- USB-C to USB-C cable: Can be charged with any USB-C to USB-C cable. We do recommend using a cable that can support 100W to charge up Flash 2.0 at it's max speed. Be warned that most USB-C cables are not designed or rated to handle 100W (20V/5A) and require an E-Mark chip which prevents the circuit from overloading and allows the high power to be reached safely. Our Infinity Cables comes with an E-Mark chip meaning it can be used safely. You'll be able to find out more here.

smack bang on point for 20,000 mAh
My Flash 2.0 charges my Note10+ 5G from around 10% to full a little more than 4 times. Given the battery capacity of my phone is 4300mAh and taking into account the charging losses, the capacity of the Flash battery pack seems to be smack bang on point for 20,000 mAh.
Charging compatibility
Just got mine hooked it up to my new XPS 17 and it worked for charging it! Amazing
Charging coverage
Received the Flash 2 today, So far I’m happy! Charging laptop, iPad and phone & watch wireless works fine. Charging phone wireless isn’t top speed but is ok. Being able to charge the AppleWatch with it is a big plus.
device coverage
Got the Powerbank here in Sweden, and so far its Great! There is no scuffs or scratches on it, which is great to see. Charges a Dell Latitude 5580, An Iphone XS and an Apple watch simultaneously without issue. but there is the issue of it stopping charging when in pass-through charging, that being when you stop charging the Flash it will stop charging connected devices. A little Frustrating, but something to get used to. Might be the flash switching from wall power to battery?
best power bank
I’m delighted with mine, it operates as described, and it was well worth the wait—my best power bank!
