Scoring method

How this ranking is scored

Scores are based on price, specs, usability, expansion and trust.

100-point total

Scores are compared by capacity-band use case. Value and size are compared within the same band.

Price

20点

Sale price, distance from historic lows, yen/Wh, set value and availability.

Spec

25点

AC output, USB-C/A, charging speed, solar input and UPS-related practicality.

Use

20点

Weight, size total, placement, portability and fit for real use cases.

Expansion

15点

Expansion batteries, max capacity, solar ecosystem and Amazon set availability.

Trust

20点

Brand, warranty, support, safety, hands-on review and data confidence.

Real sale price

Uses Keepa averages, historic lows and discount frequency, not only list prices.

Yen/Wh is relative

Yen/Wh is compared within the same capacity band because market prices differ by size.

No credit for unverified data

Prioritizes data confirmed by official sources, Amazon, Keepa and hands-on checks.

Open detailed scoring criteria

Detailed Japanese scoring criteria are used internally and will be translated in a future update.

Large (1000〜1500W class)

防災・メイン電源

Pre-purchase checklist

容量使いたい家電を何時間動かしたいか
AC出力電子レンジ、ケトル、ドライヤーなど高出力家電を使うか
USB-CノートPCやタブレットを急速充電したいか
重量家の中だけか、車載・キャンプでも持ち運ぶか
拡張性後から容量を増やしたいか
セットソーラーパネルや拡張バッテリー付きの方が安くないか
最終価格クーポン、ポイント、販売元をAmazonで確認したか

FAQ before you buy

Q. どの容量を選べばいい？▾

まずは「何を、何時間使いたいか」で選ぶのが基本です。スマホやノートPC中心なら最小容量〜小容量、キャンプや車中泊でライトに使うなら中容量、停電対策や家庭用バックアップまで考えるなら1000Wh以上、防災をより重視するなら2000Wh以上も候補になります。迷う場合は、最初に1000Wh前後を見ると選びやすいです。価格、サイズ、出力、使える家電のバランスが良く、初めての1台としても選びやすい容量帯です。

Q. 単体とソーラーパネルセットはどちらがおすすめ？▾

短時間の利用や、家で充電して持ち出すだけなら単体でも十分です。一方で、停電対策、車中泊、キャンプ、防災備蓄まで考えるなら、ソーラーパネルセットも必ず確認した方が良いです。セール時は本体とソーラーパネルを別々に買うより、セットの方が安くなることがあります。特にPrime Day期間中は、単体価格だけでなく、セット価格、クーポン、ポイント、販売元まで確認して判断するのがおすすめです。

Q. 過去最安に近ければ買い時？▾

過去最安は重要な目安ですが、それだけで判断しない方が安全です。同じ価格でも、頻繁にその価格まで下がるモデルと、年に数回しか下がらないモデルでは、買い時の意味が変わります。このランキングでは、過去最安との距離、値下げの珍しさ、容量単価、スペック、セット内容を合わせて評価しています。購入前には、Amazonの商品ページで最終価格とクーポン条件を確認してください。

Q. 容量とAC出力はどちらが大事？▾

容量は「どれだけ長く使えるか」、AC出力は「どれだけ大きな家電を動かせるか」です。例えば2000Whあっても、AC定格出力が低いと高出力家電は使いにくくなります。逆に容量が小さくても、AC出力が高ければ短時間だけ大きな家電を動かせる場合があります。防災や家庭用バックアップでは、容量と出力の両方を分けて確認するのが大事です。

Q. USB-Cの出力はどこを見ればいい？▾

USB-Cは「口数」だけでなく「1口あたりの最大出力」を見てください。15W前後だとスマホや小物充電中心です。60W前後ならタブレットや一部ノートPC向け、100W以上あるとノートPCや最新スマホの急速充電にも使いやすくなります。100W級のUSB-Cが複数あるモデルは、PC、タブレット、スマホを同時に充電しやすく、日常使いでも便利です。

Q. 拡張バッテリー対応は必要？▾

最初は1000Whクラスで始めて、あとから防災用途を強化したい人には大きなメリットです。拡張対応モデルなら、使い始めてから「もう少し容量が欲しい」と感じたときに追加できます。一方で、軽さや価格を優先するなら、拡張非対応でも満足度が高いモデルはあります。長期停電対策を重視するなら拡張対応、価格や持ち運びを重視するなら非対応モデルも含めて比較するのがおすすめです。

Q. Prime Day後もこのランキングは使える？▾

使えます。ただし、セール価格やクーポンは期間中と期間後で変わります。Prime Day後は、通常価格、過去最安、容量単価、スペック、用途別の向き不向きを中心に、通常の容量別ランキングとして更新していきます。購入前には、必ず最新のAmazon価格と販売条件を確認してください。
