## Customer Reviews

### ⭐⭐⭐⭐⭐ 買って良かった
*by ア***ー on May 16, 2025*

100V仕様の電動工具も 普通に使えます 私はベルトサンダーを使ってみましたが問題なく動作するし、バッテリー駆動の機器よりも長い時間使えそうです

### ⭐⭐⭐⭐⭐ 手ごろなサイズと重さで500Wの高出力。
*by R***R on June 3, 2024*

W:315mm、D:186mm、H:186mm、重さ：約6.1kg（実測値）コンパクトなサイズで500Wの出力、瞬間最大1000Wとのことです。入力（充電）は３種類あり、下記のアダプターまたはケーブルが付属しています。入力端子は共通の専用DCコネクターです。①25V,4A(100W)のACアダプター②12Vのシガーソケット③太陽光パネル（MC4コネクターからの変換）また、アンダーソンプラグ入力もあるので、それに対応した太陽光パネルからの充電もできます。出力はAC:100V×2DC:14V8A、シガーソケット×1、DCプラグ×2USB:QC3.0×3(Type-A)、PD 60W×1(Type-C)面白いのは上部にワイヤレス充電機能があり、スマホをケーブルなしで充電できます。背面にはけっこう広範囲を照らせるLEDパネルがあり、色味は電球色です。我が家ではキャンプで発電機を使って炊飯ジャーでご飯を炊くのですが、今度は400Wの炊飯器があるのでこの電源でご飯を炊こうと思っています。普段家ではこのバッテリーの寿命を維持するためにスマホなどの充電に使い、本機への充電は太陽光パネルから行っています。

### ⭐⭐⭐⭐ 18650三元系リチウム電池の特徴であるコンパクトで軽量
*by S***I on April 27, 2024*

GRECELL ポータブル電源 519wh大容量 500W出力 ポータブルバッテリー 家庭用蓄電池 140400mAh 純正弦波 PD60W急速充電 10台デバイス同時充電 瞬間最大1000W出力重量は本体：6.06kgアクセサリー一式：0.625kg各ボタンはチョイ押してON-OFF電源ONでDC(+USBも)は出力されますパススルーには非対応でPOWER が入力されるとACは切れます18650三元系リチウム電池を使用しているので取扱説明書にも充電サイクル数の記載は有りませんが500回程度になるかと思いますまあ、18650三元系リチウム電池の特徴であるコンパクトで軽量にはなっていると思います入力電力は100W程度なのでフル充電に6時間以上はかかりますね入力電圧は12～26VとのことでMax105Wのようです取圧説明書には5分以内に操作しないとシャットダウンすると書かれてはいますけど無出力状態で20秒程で画面の照明は消えるが数分経っても電源は切れません？？？保管時のことは詳しく書かれていませんが残量20％未満の時は充電するようには書かれていますちなみに送られてきた時は53％程度でしたそれを思うと50～80％で保管と考えておいた方が良いでしょうねできれば、リン酸鉄リチウムとパススルーとスマホ対応は欲しい機能ですね
