Ecoflow’s Rapid Pro power bank is one of the most powerful portable batteries we’ve tested, and it’s selling at an all-time low price of $149.99 ($70 off) at Amazon and from Ecoflow’s store during 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 — enough to charge four devices at once — and it has a maximum power output of a whopping 300W. And, yes, you’re allowed to bring this model on a plane, since it falls just below the FAA’s 100Wh limit for carry-on bags.
That speed allows you to charge a pair of 16-inch MacBook Pros from zero to 50 percent in about half an hour, with enough juice left over to charge an iPhone. The Rapid Pro power bank itself takes about 40 minutes to charge when you pair it with one 140W wall adapter, but you can cut that time nearly in half by connecting it to two power adapters simultaneously, supporting up to 280W recharging speeds. The Rapid Pro Desktop Charger that’s sold separately (not currently available in the US, it seems) lets this power bank recharge at a super-fast 320W speed.
In our tests, the battery pack was able to charge an iPhone 15 Pro nearly four times before running out of power. Ecoflow claims the power bank will keep its full capacity for 300 cycles before dropping to 80 percent, which should be sufficient for most of your tech. It’s far from the most compact battery pack, but what you lose in portability you gain in raw power.
