We are knee deep in winter and those of you who have to deal with the occasional (or frequent) power outages should consider having a power station on hand to keep your mobile electronics for emergencies. If you're of the same mind and are thinking of checking Amazon out for the best deal, then be aware that you can get considerably better pricing an identical brand and model elsewhere.
我们已深陷冬季，那些需要应对偶尔（或频繁）停电的朋友应该考虑备一台便携式电源，以便在紧急情况下为移动电子设备供电。如果你也这么想，正打算去亚马逊看看有没有最优惠的价格，请注意，在其他地方购买相同品牌和型号的产品可以获得更优惠的价格。
Right now, AliExpress is offering the Ecoflow River 3 230Wh LiFePO4 power station for just $129.74 after you apply $15 off code "USWS15". Compare that to $190 on Amazon currently.It's sold through Ecoflow's official Aliexpress storefront and it ships from a local US warehouse so your order delivers quickly and you don't need to worry about additional tariff fees.

The Ecoflow River 3 is a truly portable power station that weighs in at under 8 pounds and is 30% more compact than its River 2 precedessor. The AliExpress model has a slightly lower 230Wh capacity compared to the 245Wh on Amazon. Other than that, the two are identical; it has two 300W (600W surge) AC outlets, one 100W USB Type-C port, and two 18W USB Type-A ports. The River 3 can be recharged using traditional AC from 0% to 100% in only one hour.
Ecoflow River 3是一款真正便携的电源，重量不到8磅，比其前身River 2紧凑了30%。与亚马逊上245Wh的版本相比，AliExpress版本的容量略低，为230Wh。除此之外，两者完全相同；它拥有两个300W（600W峰值）交流插座、一个100W USB Type-C端口和两个18W USB Type-A端口。River 3仅需一小时即可通过传统交流电从0%充电至100%。
The River 3 uses LiFePO4 cells, which are safer and retain their charge longer than other lithium battery types. The 230Whr battery is meant for lower powered electronics like your PC or laptop, phone, tablet, or just about anything else that doesn't use too much electricity (ideally under 200W). Power hungry electronics and appliances won't last long.
River 3采用磷酸铁锂（LiFePO4）电芯，比其他类型的锂电池更安全且保电时间更长。这款230Wh的电池适用于功率较低的电子设备，如电脑或笔记本电脑、手机、平板电脑或其他任何耗电量不大的设备（理想情况下低于200W）。耗电量大电子设备和电器的续航时间不会太长。
Although the River 3 is typically used as a mobile backup power solution when you have no available grid power, it can also work as an always-on passthrough AC power strip. It has an EPS function that will automatically swap to battery power when there is a power outage. The shutoff delay is less than 10ms, which is fast enough for even sensitive electronics like PCs to remain powered on during the switchover.
虽然River 3通常在没有市电时用作移动备用电源解决方案，但它也可以作为始终开启的直通交流电源排插使用。它具有EPS功能，在停电时会自动切换到电池供电。切换延迟小于10毫秒，对于电脑等敏感电子设备来说，这个速度足以保证其在切换过程中保持通电状态。
