You never know what you're really going to get sometimes. This time was a very pleasant surprise. We're all Android phones here, and Super Fast Charging seems a premium with so many older chargers on hand and older, cheaper tech on shelves being sold at bargain prices.Not with this. This small battery charges itself quickly and charges your phone even more quickly. Super Fast Charging has my Note 20 and Z Fold 7 both at 100% faster than anything else we currently carry - and we've got plenty of options. When traveling, size and weight are important to minimize while speed of charging is also a premium convenience. This checks both boxes.

Super FAST charging CONFIRMED for Samsung Galaxy S2x Ultra. Very light and convenient to use. I always take it along now because its so light and small. It packs 2 full charges minimum for my phone.

Summary: Output 38 Wh vs. 37 Wh rated, 193g, 0.20 Wh/gram. Top notch performance for a good price.I bench tested a new unit on its second charge-discharge cycle. It output 34 Wh (at 5.1V and 1.50A) from 100% to 10% charge. Throughout that range the ratio of energy supplied to the digital readout remained linear. Therefore, the apparent output capacity to 0% is 38 Wh. This is in excess of the rated storage capacity of 37 Wh and claimed output of 31 Wh. On my scale, the unit (with built-in cable) was 193 grams (+/- 2g).1.) Manufactures label was very informative. Their statement "Output Capacity: 6200mAN/5V/31 Wh (Typical energy loss accounted)", was the most honest assessment that I have seen in the power bank market.2.) Excellent power density. You have to change price points and target the Nitecore series if you need to do any better.3.) The digital display was accurate and much more useful than a 4-light approach. Nothing worse than being in the middle of the nowhere and have your power bank go from 2 lights to dead in 15 minutes.4.) Modern smartphone have batteries of about 12 Wh, so this power bank will realistically charge a fully depleted phone 2 + times.The only complaint I have on the whole unit is no 'compact storage' for the built-in charging cable. In its stored configuration the cable always forms a hang-loop. I'd prefer if it stowed flat to the power bank somehow.I'll be stress testing this unit on a week long backpacking trip and may update this review with that experience.Newbie Notes:Marketers name power banks based on the current capacity of their internal batteries at their native voltage. Standard storage batteries are 3.6V. Typical USB output is 5V. So, an advertised 10,000 mAh battery (at 3.6V) is typically 36 Wh and equivalent to 7,200 mAh at 5.0V.I test at 5V and 1.5 Amps, because it is a bit gentler on the battery pack and is consistent with the 2 Amp charge demand of most of my devices. If you use the power bank at the full rated current of 3 Amps, losses may increase and reduce apparent capacity.

it works just fine with decent recharging speed, however, if you use it to charge an iPhone 14 Pro you need to buy anusb c to lightning adapter which is not included...that should have been mentioned...

Exactly as described. This power bank is compact and especially convenient with the attached USB-C cable.

Lightweight and charges my phone quickly

This works great and holds a charge I just wish it came with an iPhone cord too.

Great little power bank that can power my Canon R5C. Great for all day use!
