Note: A single flashing light indicates 1-25% remaining, so plan accordingly to avoid carrying a dead weight.

Real-World Performance

It arrived at 50% charge and fully powered my phone twice (30% to 100%) before depleting. Full recharges take about 9 hours, but it recharged my phone six times on a single cycle.

For the OnePlus 5T, it delivered a 30-100% charge in 90 minutes—15-30 minutes faster than a standard charger.

Impressively, it stayed cool even charging my phone and headphones simultaneously, a testament to Anker's thermal management.

Airline Travel Approved?

At 72.36Wh, it complies with most airlines' 100Wh carry-on limit. Pack it in your hand luggage only—never checked baggage.
