问大家
: Is it reliable as a car jump starter battery? 用作汽车启动电池可靠性高不？
: Better not. Jump starter batteries excel in instant high current, which differs from this battery's purpose. Haven't tried it myself. 最好别 jump battery的特点是瞬时电流很强 和这种电池的用途不一样。我没试过
: Wait, aren't these types of batteries usually for outdoor power supply? 啊这，一般这种电池不都是用来户外供电用的么
: What's the background of this company? 这家是什么来头?
: A Chinese brand mainly targeting the European, American, and Japanese markets for outdoor power supplies and energy storage solutions. 中国的主要面向欧美、日本市场做户外电源和储能解决方案的品牌
: Jinggong Electronics from Zaozhuang, Shandong. They also specialize in new energy, and have a branch company in the US. 山东枣庄的精工电子，也是专搞新能源的，美国有分公司
: For those with solar panels at home, can this be a cost-effective alternative to Powerwall? What additional equipment is needed? 家里有太阳能的，这个可以平替power wall吗？需要什么额外设备？
: A cheaper alternative can be bought for just a few dozen bucks. 买个几十块就能替代了

: A manufacturer from Shandong. This is definitely dumping. Even if the price doubles, it's probably still just the cost price for American manufacturers. 山东的厂家，这妥妥的倾销了，这价格翻倍，估计就是美国厂商的成本价了。
: This price is dumping? The ones on eBay are practically free then. 这价格还倾销？eBay 上的那些只能算免费送了
回复 @匿名用户 : Haven't tried it. I'm worried because the C port is marked as output-only, so I'm afraid of damaging the hardware. Theoretically, that's not possible. The battery cells are very solid, so even if there's zero loss, charging like that you can only get up to 500Wh. In practice, when charging itself with random chargers, most of the time it pulls over 100W, but even then there's no way to reach 85% in 5 hours. If you don’t switch chargers, charging from 0 to 100% takes at least 9 hours. 没试过，c口写着只能单向输出的怕把硬件搞坏了，理论上来说不可能，里面电芯挺实的这么充即使完全没损耗也只能到500wh，实操随机充电器自充绝大多数时间都超过100w，也没有办法5小时到85%。不换充电器挺慢的从0到100%至少9小时。
