Ecoflow’s Fast Professional energy financial institution is likely one of the strongest transportable batteries we’ve examined, and it’s promoting at an all-time low worth of $149.99 ($70 off) at Amazon and from Ecoflow’s retailer throughout Black Friday. The 27,650mAh battery pack has three USB-C ports (one 140W port, plus two 65W ports), a two-foot-long retractable 140W USB-C cable — sufficient to cost 4 units without delay — and it has a most energy output of a whopping 300W. And, sure, you’re allowed to carry this mannequin on a aircraft, because it falls just under the FAA’s 100Wh restrict for carry-on luggage.
That velocity lets you cost a pair of 16-inch MacBook Execs from zero to 50 % in about half an hour, with sufficient juice left over to cost an iPhone. The Fast Professional energy financial institution itself takes about 40 minutes to cost whenever you pair it with one 140W wall adapter, however you may minimize that point practically in half by connecting it to 2 energy adapters concurrently, supporting as much as 280W recharging speeds. The Fast Professional Desktop Charger that’s offered individually (not at present obtainable within the US, it appears) lets this energy financial institution recharge at a super-fast 320W velocity.
In our exams, the battery pack was in a position to cost an iPhone 15 Professional practically 4 occasions earlier than operating out of energy. Ecoflow claims the facility financial institution will preserve its full capability for 300 cycles earlier than dropping to 80 %, which must be adequate for many of your tech. It’s removed from essentially the most compact battery pack, however what you lose in portability you achieve in uncooked energy.
